The main business of Liaohe Oilfield Branch of China Oil and Gas Co., Ltd.

Liaohe Oilfield adheres to the guidance of Scientific Outlook on Development, closely focuses on the goal of building "Double Thousand" enterprises and the development idea of "33343", grasps the general tone of striving for progress while maintaining stability, and strives to promote overall coordinated development, thus forming a pattern of coordinated development of oil and gas core business, engineering technology, engineering construction, natural gas utilization, diversified business and mining area services.

Exploration and development: In accordance with the exploration and deployment principle of "deepening depression, speeding up beach area, breaking through periphery and expanding new area", we have vigorously carried out exploration of buried hills and lithologic oil and gas reservoirs, actively promoted the application of new exploration technologies, and successively discovered reserves of multiple scales such as buried hills in Damintun sag and Xinglongtai buried hills. Deepen the rolling exploration and development in the old areas, strengthen the reservoir evaluation, and make the crude oil output10 million tons stable for 24 years. The concept of "secondary development" was first put forward and successfully put into practice, which became a revolutionary development measure in the petroleum industry. Xinhai block 27, with horizontal wells as the main development means, has become a demonstration block for the secondary development of China petroleum.

Engineering technology: mainly including oil testing, overhaul sidetracking, routine operation, fracturing, acidizing, etc. It has the advantages and characteristics of high-pressure water well under pressure and green workover operation, and has complete technologies such as steam injection and heat insulation, wellbore lifting, workover operation, sand control and sand discharge, dynamic monitoring of the whole process of heat collection and transportation, and advanced treatment of sewage. According to the reservoir characteristics of Liaohe Oilfield, a set of fracturing and acidizing technology series has been formed, especially the research and application of fine layered fracturing technology and hydraulic sand blasting fracturing technology, which has realized the effective development of high pour point oil rare in the world. The first self-designed hydraulic jet fracturing horizontal well has been a complete success recently.

Engineering construction: responsible for general contracting, survey, design, construction, supervision and inspection of oil and gas field surface engineering, with the design and construction capabilities of heavy oil, high pour point oil gathering and transportation treatment, heavy oil sewage treatment, offshore oil engineering, long-distance pipeline engineering, bridges and expressways. It has successively contracted the construction of Qin-Shen line, participated in famous projects such as West-East Gas Pipeline, Shaanxi-Beijing Pipeline, Algerian Pump Station Project, oil pipeline construction in Sudan and other countries, and participated in the construction of Guangzhou-Shenzhen pipeline.

Natural gas utilization: As a rare opportunity for the company to achieve sustainable development and an important mission to support the clean and green development of the old industrial base in Liaoning, the natural gas business in Liaohe Oilfield takes the "gasification Liaoning" project as an opportunity to comprehensively straighten out the management and operation system, carefully organize the trunk and branch pipe network projects, and vigorously expand the natural gas business market. Natural gas utilization has become the most growing and strategic business and an important economic growth point in the oilfield. Up to now, the pattern of "two lines and one storage" mainly consisting of Qinshen pipeline, Shen Da pipeline and double 6 gas storage has basically taken shape. The gas business has successfully entered Liaoning 1 1 city and Chifeng market in Inner Mongolia, and the effect of replacing oil with gas is remarkable. 201/kloc-0 replaced 707,000 tons of fuel oil every year, and the cumulative sales volume was 10.

Diversification: mainly including petroleum equipment, petrochemical industry, engineering construction, supporting services and trade, with an annual sales income of nearly 10 billion yuan. The drilling tools, top drives, pipes and other products of diversified enterprises are exported to Britain, Switzerland, Russia, Kazakhstan, Iran and other countries, and the development speed and economic benefits of diversified enterprises have been improved simultaneously with their main businesses.

Mining area services: mainly provide professional management and services such as property and public utilities, social welfare, old-age care and medical and health care. Focusing on the three functions of ensuring production, serving life, maintaining stability, and building a harmonious demonstration mining area, reform and innovation, pioneering and enterprising, and gradually realize socialized service, regional management, enterprise operation, and market-oriented operation, and constantly improve the management level and service quality, effectively improving the quality of life and environmental quality of the broad masses of employees, and ensuring the efficient and sustainable development of the oilfield.
