Since the beginning of this year, Fuling Shale Gas Company of Jianghan Oilfield has strengthened the comprehensive management and dynamic management of old wells, accelerated the construction of booster stations, and strengthened the treatment of low-efficiency wells, so that the production of old wells in the gas field has achieved steady progress
.
As of June 3, the output of old wells in the gas field reached 3.
008 billion cubic meters, an increase of 168 million cubic meters over the plan
.
Fuling Gas Field insists on scientific management of gas wells, systematically records dynamic data such as flow pressure, well testing, and gas production profiles, strengthens dynamic management and monitoring of gas wells, formulates a dynamic analysis system with daily production guarantee and weekly summary, strictly prevents abnormal situations, and gradually improves old wells.
Gas stabilization capability and gas field recovery
.
At present, the overall recovery rate of the Jiaoshiba block has increased to 23.
3%, nearly doubling from the beginning of development
.
In response to the declining production of old wells, Fuling Gas Field has adopted differentiated technical measures such as pressurized production, compressor gas lift, foam drainage, inspection and workover operations, and scientifically implemented "blood-boosting ventilation" treatment methods for old wells to continuously improve the "healthy" wellness of gas wells.
Index”, the comprehensive decline rate has been effectively controlled
.
At present, the gas field has implemented 202 low-efficiency well treatment, and the annual cumulative gas increase has increased by 3.
31 million cubic meters compared with the plan
.
In terms of booster production, Fuling Gas Field has actively put into operation booster stations, established an efficient maintenance mechanism, promoted remote intelligent booster, regional booster, and ensured the efficient and energy-saving operation of booster stations.
This year, the boosted gas volume increased by 83 million cubic meters compared to the plan.
