China News Service, Chengdu, December 29 (Du Cheng, Yang Mingyue, Zhao Yangchun) PetroChina's Southwest Oil and Gas Field Chuanzhong Oil and Gas Mine revealed on the 29th that the oil and gas mine will produce 10 billion cubic meters of self-operated natural gas in 2021.
It is reported that this is the six consecutive years since 2016 that the annual output of natural gas in the central Sichuan oil and gas mine has exceeded "10 billion", laying a solid foundation for another 10 million tons during the "14th Five-Year Plan" period.
According to reports, since the beginning of this year, the oil and gas mines in central Sichuan have been scientifically deployed for exploration and development. Aiming at new areas and new layers, vigorously promote the test production evaluation of the Dengying and Qixia formations in the Longnüsi block, and the Maokou formation in well Jiaotan 1 to find out the production capacity and production of gas wells. Laws to prepare for subsequent exploration and development.
For the Longwangmiao Formation gas reservoirs, we will continue to optimize and improve the development technology plan, strengthen the overall water control of the gas reservoir, and finely carry out the production adjustment of the gas reservoir to achieve the first time in recent years to "zero increase" in water-producing wells and water-producing risk wells.
Aiming at the old area, the oil and gas mine has done a good job of maintaining the productivity of low-yield gas wells, adjusting the dynamics of the main gas wells and tapping the potential of potential gas wells. The annual measures have increased production by 100.5 million cubic meters. The overall daily production of the old gas fields has remained above 2.5 million cubic meters, and the comprehensive decline rate has dropped to- 3.54%, achieving "negative decline" in output in the old area for the first time, setting a record high.

In terms of efficiently advancing production capacity construction, the Sichuan Oil and Gas Mine deepened the “three advances, two synchronizations, and two optimizations” project management measures to effectively accelerate the pace of production capacity construction, and built 18 production facilities throughout the year, adding 3.24 million cubic meters of daily production capacity, and contributing output ahead of schedule 25.7 million cubic meters.
Promote drilling and testing projects in an orderly manner, establish a docking mechanism for self-managed wells and commissioned wells, and do a good job of on-site supervision of key links and large-scale constructions to ensure construction progress.
In terms of basic management, the oil and gas mine continues to improve the "gas reservoir-well area-single well" integrated transparent gas reservoir management system to systematically improve the management level of production dynamic analysis; strengthen the management of the entire life cycle of equipment, the comprehensive equipment integrity rate, and comprehensive utilization It pays close attention to wellbore integrity management, formulated the "six tables and one map" standard basic management, and initially formed a "transparent wellbore" management model; optimized the implementation of gas quality blending, effectively used the processing capacity of the purification device, and stabilized The operating time rate of Changman is greater than 99%, and the "Three Zeros" goal has been successfully achieved.
In the field of safety and environmental protection, the Sichuan Oil and Gas Mine paid close attention to the implementation of the "two-site" control measures, normalized hidden hazard management, improved hidden hazard inspection standards, and consolidated special inspection mechanisms; systematically formulated three major types of special improvement actions to effectively build long-term improvement Mechanism; Strengthen green environmental protection management, and comprehensively complete the goal of environmental hazard management; improve grid management and personnel flow management and control, and maintain "zero infections and zero epidemics" for all employees in the mine.
