Western Drilling Focuses On Key Basins to Assist Oil and Gas Production

As of April 7, the number of key Wells drilled in the West since the beginning of this year has reached 61, and the drilling depth of 188,000 meters has been completed, helping the oil field to drill multiple high-yield oil flow Wells.

Western drilling focuses on the key basins in the west, strengthens the project system management of key projects, promotes the "five integration" of engineering and geology, engineering and professional technology, geology and orientation, scientific research and production, and creates high-quality projects, fully guarantees the production of key regions, and supports the upward arrow of oil and gas production.

Focusing on exploration well drilling and completion period is long, complex time rate high blocking point, western drilling to establish a special class system for exploration well work, break the independent operation mode of each specialty, integrate the promotion of "special class operation + efficient cooperation" mode, give full play to the advantages of technology integration and intensive management, and promote drilling speed. The company integrated deep horizontal Wells to speed up production technology research, detailed demonstration of the construction plan, to ensure that the first "three-high" horizontal well Kangtanyi 001H in Jundong New Area of Tuha oilfield shortened the completion period of 53.46 days, ahead of the completion of 14 volume fracturing construction.

The company implements the low-cost strategy, promotes the benefit development of shale oil through integrated research, factory operation, and information decision-making, optimizes and improves the block acceleration template, improves the drilling and fracturing timeliness of shale oil, and accelerates the "realization" of oil and gas resources. In response to the challenges such as long development cycle and difficult benefit development of shale oil in northern China, the company has carried out fine management, carried out single well site realism, and adopted applicable technologies to achieve the mechanical drilling rate of the target zone of MaX5126, the first high-inclination well in the pilot test area, increased by more than 80%, and the overall speed of the whole well increased by 40%. In Jimsal area, a national continental shale oil demonstration zone, the company gave full play to the main role of the drilling chain, established a "well engineering + professional" technical team with integrated office of various specialties, and promoted the work of "drilling speed, shaft quality and complex control" by matching the standard and table, and updated the daily gain record of the block.

Focusing on the construction of gas storage in key basins, western drilling integrates superior resources, highlights quality and efficiency, upgrades the service mode of the whole life cycle of the wellbore and the whole industrial chain, realizes the integration of manpower, technology, equipment and materials, and improves the ability to solve problems in a package. With well and cementing quality as the core, the company has accelerated the construction of Wenjisan gas storage cluster in Tuha Oilfield through project leadership, expert control and joint management. At the same time, the united oil field has well designed the wellhead quality, accurately identified the complex pressure system reservoir such as the fault zone, carefully formulated the speed and efficiency improvement plan, followed the on-site construction in real time, optimized and adjusted the construction parameters, and effectively ensured the first well of the domestic first plateau gas storage - Mabei gas storage in Qinghai Oil Field was completed in advance.
