According to the China Petrochemical News Network, Southwest Oil and Gas Production Plant No.
3, in accordance with the idea of “controlling reduction of high-yield wells, stabilizing production of middle-yielding wells, and improving efficiency of low-efficiency wells”, deepened the analysis and research on the production dynamics of gas reservoirs and gas wells, strengthened dynamic tracking analysis, and actively promoted Production capacity construction, do a good job in the management of gas wells "one reservoir, one well, one time and one policy".
The annual gas production of the Zhongjiang block responsible for development has increased from 760 million cubic meters in 2016 to 1.
07 billion cubic meters in 2020, as of July 2021.
The gas production is 5.
1 billion cubic meters
The technical staff of the plant actively carried out research on the bubble drainage mechanism of high-condensate oil, cyclically improved the optimization process system, carried out the evaluation of gas source wells, carefully designed the gas lift process between wells, and focused on the development of wellbore purification, anti-blocking and unblocking, and water-locking technologies.
A series of high-condensate oil and gas well drainage and gas recovery technologies based on foam composite drainage technology and complete interwell gas lift, downhole throttling, bottom-hole purification and other technologies have strongly supported the steady and increased production of gas wells in the Zhongjiang block
Since 2015, the plant has implemented various types of bubble drainage maintenance measures for nearly 40,000 well-times, increased the production of natural gas by more than 85 million cubic meters, and increased the bubble drainage efficiency from 79% to 91%
