Brief Introduction of China Petrochemical Company East China Branch

Through continuous exploration and practice, East China Branch has gradually formed a series of exploration and development methods and technologies for complex ultra-small fault-block oil fields and lithologic-structural composite oil and gas fields with low porosity, low permeability and low abundance. Three-dimensional seismic exploration, directional well, cluster well, horizontal well, slim hole sidetracking, sidetracking horizontal well, fine reservoir description, remaining oil research, reservoir protection, hydraulic sand fracturing, layered water injection, deep profile control and oil displacement, carbon dioxide huff and puff and WPS tertiary oil recovery technology have been widely used in oil and gas field exploration and development, effectively promoting exploration and development production, improving reserves utilization and recovery rate, and controlling the natural decline rate of old oil fields. After decades of exploitation, the small oil fields in northern Jiangsu under its jurisdiction are still in a good state of stable production and increased production. Since 1990s, East China Branch has actively explored new areas of oil and gas exploration in southern Songliao. After nearly 10 years of unremitting efforts, in 2003, an oil and gas breakthrough was made in Yaoyingtai in Songnan area, and in 2005, a major breakthrough was made in Yaoyingtai sag and fault depression, and a large oil and gas field of 100 million tons was discovered.

Since 2008, East China Branch has begun to explore the new energy field, and carried out unconventional oil and gas exploration and development with coalbed methane, shale gas, oil shale, combustible ice and uranium ore as the main materials. In Jiangsu, Xinjiang, Shanxi, Shaanxi, Henan, Anhui, Guizhou, Chongqing and other places, it has become a professional team for unconventional oil and gas exploration and development of China Petrochemical. We vigorously develop unconventional oil and gas resources such as coalbed methane and shale gas. Actively participate in the research work of the reserve strategic replacement area and carry out forward-looking research in the lower Yangtze area of South China; Actively respond to China Petrochemical's oil and gas resources development strategy, and constantly expand the domestic and international oil and gas field exploration and development market. In order to meet the needs of the scientific development of oil and gas exploration and development, we should adhere to the principle of talent and technology, pay attention to talent training and introduction, and establish long-term relationship of talent training and technical cooperation with relevant domestic universities.

At present, we are actively carrying out the "three pioneering efforts" represented by unconventional oil and gas resources development, fully implementing the unconventional oil and gas survey in China Petrochemical Company, exploring the occurrence law of unconventional oil and gas resources, and striving to overcome the technical problems of unconventional oil and gas exploration and development. In order to realize the sustained, effective and harmonious development of the enterprise in an all-round way, we sincerely hope to strengthen cooperation with people in the industry, blaze new trails and achieve a win-win situation. Guided by Scientific Outlook on Development, we will make great efforts to consolidate the foundation of oil and gas resources, change the development mode, intensify structural adjustment, comprehensively improve the quality and speed of development, and strive to build a million-ton oil and gas field by the end of the Twelfth Five-Year Plan.
