Sinopec News Network reported on May 25, Southwest Oil & Gas Company's Yuanba gas field, Yuanba 27-2 well, whose gas production exceeded 1 billion cubic meters, maintaining stable and high output for 5 years, maintaining a daily output of 600,000 cubic meters, becoming Yuanba The 10th Gongxun well in the gas field with a gas production of over 1 billion square meters.
In recent years, as the production time of high-yield wells such as Yuanba 27-2 has been prolonged and difficulties have appeared to restrict high and stable production, Southwest Oil and Gas Branch has carried out fine classification of gas wells, well-divided strategies and classified management, and meticulous care of high-yield wells and fine management of abnormal wells.
High-sulfur wastewater is the most prominent and most serious problem in the high and stable production of "Mongxun Wells" in Yuanba Gas Field.
In order to ensure the safe operation of the Yuanba gas field, Southwest Oil & Gas Branch optimized the safety inspection mode, implemented the "centralized monitoring, area inspection" mode in the Yuanba gas field, and implemented "centralized monitoring + area inspection + watchkeeping" for special abnormal wells.
