Use new technology zhongyou logging of oil and gas exploration well logging

Date:Jul 20,2011

The end of June, and the Chinese well logging company first in tarim oilfield medieval 21-H5 well with drilling in logging field application and promotion. In this new technology under the support, fix the eagle mountain top interface card of the layer of problem, the successful implementation of this in the first region in the eyes of the horizontal well without a drilling, drilling cycle shortens 15 days, drilling cost reduce 5 million yuan.

Logging technology progress, is a powerful impetus to speed of drilling engineering to effect.

If the drilling compared to a pair of geological found ranges, so logging is found geological a pair of eyes. "See" correct, would "catch" fast.

In recent years, oil and gas exploration and development face further, geological problem increasingly complex, oil and gas found and evaluate the growing difficult situation, and the Chinese logging companies adhering to the "all for the oil and gas," the core values, work hard to change, to speed up the development mode of independent innovation, improving the service support capacity, promote China's oil and gas exploration and development to the imaging logging times ahead.

Independent innovation, "polish" identification of the "eyes" oil and gas

March 7 to 14, held in Beijing, the "eleventh five-year plan" of major national science and technology ChengJiuZhan, "China's oil creates" once again attracted people's attention. Carrying a generations of people dream of logging EILog technology series "appearance" wonderful.

The industry, China's oil well logging company comments of independent research and development EILog fast and imaging logging system, leading Chinese oil exploration and development of full access to the imaging logging era.

This is the power of the oil to create.

In the past, the international logging market is big company of foreign "unify the whole country". Zhongyou logging company sets up the beginning of 138 sets, all lose 110 sets for domestic small nc logging equipment, a total of 14 models, measurement accuracy is bad, the operation efficiency is low. The introduction of 19 set of high precision CNC equipment are overterm service.

Because domestic imaging logging instrument all depend on the introduction, key technology was "lock", the competitive power is constrained. This become China's oil well logging people heart "silent pain".

If you don't want to be enslaved, have to learn to walk on his own. There was only one way, and that is to develop technology innovation, practice a pair of oil and gas found and recognition "eye".

By the end of 2002, with China's oil well logging professional restructuring propulsion, well logging company preliminary form scientific research, manufacture and services integrated advantage for logging technology development, provide a rare opportunity.

EILog fast and imaging logging system is an instrument of big project, and system, idea. The system of the Lord of ChenBao circuit designers still remember, research for more than a year, in the most nervous time, he and all the group members often for a root go line and a structural detail discussion late into the night, repeatedly, don't pass any details.

Scientific research personnel to adhere to the "scientific research and production of photograph union, logging and oil and gas in coordination, put forward the policy of" "project from production, from power, prototype application is a product, promotion efforts must be" train of thought, all the products r&d link standard requirements, all part of oil and gas according to identify the purpose to design to ensure the instrument advancement and practicability and reliability.

September 25, 2005, changqing oil region by zhuang 1 well logging construction officially launched. This is the first EILog out, industry is concerned inside and outside. Undertake the mission of the 60101 team well, two times in five hours, safety and quality to finish the mouth logging construction, than traditional numerical control logging save half the time.

After all the research and development personnel 2000 DuoGe crucial day and night, a new generation of high speed imaging and logging system EILog successfully developed. It was published, broke the foreign technology monopoly, overall system performance achieved the international advanced level.

This year, no doubt has become China's oil well logging development a landmark year.

At the same time, the company give full play to the logging technology research and development, logging equipment manufacturing and logging technology service integration advantages, continuously rich oil and gas layer identification method. The company independent research and development of a new generation of logging comprehensive application platform-LEAD3.0, November 2010 in changqing oil field has been formally put into production. And the same type software, domestic compared LEAD3.0 single well processing and interpretation can shorten the time average two or three hours, marked the comprehensive application of domestic supporting logging software development and promotion has made a great progress.

Up to now, the company formed to oil and gas evaluation as the center of the EILog technology series, mainly including integration conventional log, "3 2 1 1 h NMR" electric sound localization stratum, and the imaging logging evaluation with drilling well logging, well site for core parameters of the fast digital core, production logging and through the casing well logging, to explain the unity of the link database support software, and logging ERP and logging nets.

The independent innovation, speed up the pace of promoting "polish" the oil and gas found recognition "eyes". By the technology conditions before restrict, logging only stay in found that the "point" of the oil and gas layer and "face", compared to "a peep-hole view", and EILog fast and imaging logging system development, for oil and gas workers put into the "clairvoyant, not only of system integration", instrument and the imaging logging data array, and the rapid acquisition and processing with real-time and remote transmission ability, can clearly revealed about thousands of meters oil layers of the image. China's oil well logging, is experiencing oil and gas from the reservoir level to the evaluation found from "a peep-hole view" and to stereo imaging the revolutionary transformation.

The data shows, EILog fast and imaging logging system into the field use, has since 21800, basically solved well logging more than low porosity, low resistance, complex lithology, water flooded layer, the horizontal well and dense gas and other complex oil and gas layers of evaluation. Oil and gas layer identification accuracy increased by 5%, the single well the processing time shorten 40% above, logging a success rate to stay above 95%.

Do good service guarantee, playing good exploration and development of rimmon a feet ""

July 22, 2010, the "eleventh five-year plan" national oil and gas major projects subject-controlled source neutron porosity with drilling well logging tool in changqing oil field drill, test success. According to the records, with drilling and well logging curves with cable logging curves, the contrast of the formation of porosity of neutron measurement numerical curve shape good correlation, identical, real-time upload with drilling data of neutron FanYingDe layer upon layer can be a porosity variation.

The research development of personnel, participate in embracing congratulations, with tears in her eyes.

Article the real-time curves, full behind several generations of logging people dream!!!!! Marks China has become a global a few master lithology, saturation and porosity three parameters strata with drilling logging evaluation of the country.

Since, how in drilling finish at the same time logging operations, improve operation capacity and operating quality, is China petroleum engineering technology business will continue to follow unswervingly pursue. However, western companies in China to implement technology "blockade", not only don't sell instrument, even if a high price with drilling the well logging service is also a "measured" is hard to find.

Foreign can do it, why can't we? To break the monopoly abroad, creating a "China create" with drilling the well logging technology and equipment, in 2008, and the Chinese well logging company with drilling a well logging centre.

"You have to be out in 2010, the first domestic with drilling article controlled source neutron porosity site curve." In the center director, senior technical experts group company LiAnZong lead bottom, China's oil well logging people JunLingZhuang set. In no experience and reference, independent research and development on road.

Experiment, in the repeated failure after continue; Understanding, in a meeting of collision in clear. Products, in a meeting of perfect the mature.

After 600 DuoGe the tireless efforts of day and night, and by the end of 2010, and the Chinese well logging company launched domestic first set of FELWD formation evaluation with drilling, the total logging system applied for the national patent technology in 18. As soon as possible that these "tool" used in oil field production, project team in more than a year of work in the field test, fought north and south, has realized in changqing oilfield, yumen oilfield, tarim oil and gas fields of southwest nearly 20 Wells in The Times of trial and hundreds of corrective, excellence. On dec. 20, 2010, in tarim oilfield high temperature and high pressure super deep Wells tower 6000 metres high resistance stratum, using gamma lateral resistivity logging with drilling, use only 20 DuoGe hours solved cable logging instrument more than 10 days not getting the problem of the data qualified.

This is just zhongyou well logging company strengthen the service support capability of a miniature.

If the geophysical exploration is looking for structure, hydrocarbon generation reveals, reservoir, cover layer, so with drilling is hard science drilling in target zone. And could very well find and recognition, the key is how to oil and gas to play well logging "rimmon a feet." For several years, well logging company continues to expand the area of services, through to the EILog fast and imaging logging system promotion, already from a single acquisition and processing and interpretation, evolved into r&d, production, collection and processing and interpretation, as one of the service system, and initially formed with drilling logging in as a representative of the six distinctive service technology.

And "15" than at the end of the year, logging operation capacity from 10000 Wells times increased to 28000 Wells by 180%. Time, Curve classy article, 5.74% higher rate equipment a success rate increased by 4.3%.

Bear oil and gas evaluation and create the main "schlumberger"

In 2011, along with two sets in early march EILog fast and imaging logging system left zhongyou well logging company industrialization base, the group company sets of EILog promotion project in full swing.

This is the group company promote full system logging equipment upgrading and improve the ability of oil and gas services, also an important measure for well logging company technology innovation and technical service work put forward higher requirement.

Chinese for well logging company of, this is a turning point, but also challenge. In the company leadership opinion, logging business now, and the development of a comprehensive international energy group company construction to the needs of the company is not commensurate with looking for oil, gas find the needs of the work also not match.

All for the oil and gas, this is the company's core values. Service and security group company increase in oil reserve and production, and bear good oil and gas evaluation, the main force is our responsibility. This is all the logging careers.

It is based on the development of cognitive and clear accurate market judgment, for three years, according to "a well logging company zhongyou, two wings, three road and development objectives and the overall thought, give full play to its own advantages, stick to the road, dedicated to the imaging bigger and stronger, makes the Chinese" schlumberger ".

"One" : is aimed at "construction have a stronger ability to recognize the international first-class of oil and gas well logging company" the overall target, insist on leading technology, do strong, give full play to the logging "England" role; "Two wings" : is vigorously exploit the "national and international" two markets, realize fly wing to wing. Do fine, do fine domestic market, to speed up the development of "features" version of equipment, instrument with imaging and other high-end instruments lead instrument sales market. Do best, do big international market, rely on independent innovation technology go out, improve the technology services and equipment manufacturing market development level and the level, increase international competitiveness. "Three road and" : is to put the "science and technology, talent, management" as a rapid and effective pull enterprise and continuous development of three carriages, are neck-and-neck.

In the "target" to persecute, in innovation beyond, company with large field of view and big mind, and has more than 20 universities and colleges and institutes and oil and gas field enterprise develop strategic cooperation, borrow wisdom, borrows the savings strength. In service projects, exploration, development, to transform and oil reservoir of the whole production process well logging technology service business development. In depth in service to the acquisition, processing, interpretation and evaluation integration development direction. In the service market, in the unity of the group company organization and every oilfield company and drilling company support, the EILog fast and imaging logging system has 133 sets of promotion. In China, the application to changqing, north China, qinghai, tuha, the tarim, jidong and other 13 fushan oilfield. In a foreign country, China petroleum products already applied to the well logging Russia, uzbekistan, Bangladesh, Mongolia, Iran, Iraq and countries such as Burma, oil field, success continuously.

All for the oil and gas, China's oil well logging national brand is gradually to ring at home and abroad.
