Technological innovation helps improve the quality and efficiency of international business

——Twenty years of high-quality service overseas projects by the Geological Research Center of the Oriental Geophysical Research Institute

　　In May, the Geological Research Center of PetroChina Orient Geophysical Research Institute celebrated its 20th anniversary of overseas business development
.
The center closely focuses on the five overseas oil and gas cooperation zones of PetroChina, and fully utilizes the role of the “Exploration Staff Department” of PetroChina International Exploration and Development Co.
, Ltd.
in the fields of onshore risk exploration, rolling exploration, and deep-water exploration, and provides services for the implementation of the Group’s overseas resource strategy.
strong technical support
.

　　In April 2002, in accordance with the strategic development needs of PetroChina's overseas business, the former PetroChina Exploration and Development Co.
, Ltd.
(now PetroChina International Exploration and Development Co.
, Ltd.
) and Dongfang Geophysical Co.
, Ltd.
jointly established the Exploration Technology Sub-center of PetroChina Overseas Research Center (abbreviated as Overseas.
Research Center), mainly engaged in comprehensive seismic and geological research of PetroChina's overseas oil and gas exploration
.

　　Over the past 20 years, the overseas research sub-center has closely followed the development of PetroChina's overseas oil and gas business.
The business covers five major business sectors including seismic acquisition design, processing, regional geological evaluation and key target demonstration.
The region involves hundreds of basins in dozens of countries around the world
.
Based on well location deployment and seismic deployment, adhere to technological innovation and high-quality services, and continue to build supporting processing and interpretation technologies, providing strong technical support for breakthroughs in overseas oil and gas exploration
.

　　The overseas research sub-center actively promotes multi-user business evaluation and strategic deployment, and cooperates with oil companies to complete the evaluation of blocks in the British North Sea, Angola, Norway, Andes, Kenya, etc.
, forming complex rift basin target evaluation seismic exploration technology, salt-bearing basins Five related supporting technologies, including sub-salt target evaluation and exploration technology, low-amplitude trap evaluation technology, carbonate reservoir prediction technology and bedrock buried hill reservoir prediction technology, provide strong support for the sustainable development of the multi-user business of Dongfang Geophysical Exploration
.

　　During the "Thirteenth Five-Year Plan" period, the overseas research sub-centers closely followed the frontier fields of geophysical exploration, made full use of "two widths and one high" seismic data, carried out innovative research on comprehensive geological research, and focused on the application of 6 new geophysical exploration technologies and methods such as structural directional filtering.
It has carried out 15 special technical researches on earthquakes, and achieved major breakthroughs in buried hill exploration, breaking the shackles of geological understanding of "basement without potential" in Africa
.

　　Last year, the KedeniW three-dimensional project deployed to expand the scale of existing exploration discoveries and proven reserves in the central anticline of the Doseo Depression in the Southern Chad Basin was launched
.
In order to ensure that the drilling is completed before the rainy season, the overseas research sub-center efficiently organized more than 10 people to fight, innovatively applied the geological theory of strike-slip structural belt to control traps and oil and gas enrichment and a number of new geophysical techniques and methods, and provided multiple well locations.
The proposal was adopted and the drilling was all successful, further consolidating the new basin with 200 million tons of reserves
.

　　Over the past 20 years, the overseas research sub-center has been based on overseas key, difficult and hot exploration projects and geological problems that need to be solved urgently, strengthening the evaluation and demonstration of existing blocks and the evaluation of new projects, and strongly supporting the well location demonstration, geophysical exploration deployment and new projects in overseas exploration areas.
Project acquisition
.
In the past 20 years, it has operated 750 projects, and participated in 46 major breakthroughs and 47 major progress in overseas oil and gas exploration throughout the process, boosting PetroChina International Exploration and Development Co.
, Ltd.
in the Doseo and Bongor Basins in Chad, the Bilma block in Niger and the deepwater Alam area in Brazil.
The block continues to achieve major breakthroughs
.
The participation rate of major oil and gas discoveries has always remained at 100%, making important contributions to the high-quality development of PetroChina's overseas business
