摘要
增压开采是页岩气井提高采收率的重要手段,可分为单站增压、区域增压、集中增压3种模式,不同的增压模式在工程投资、最终采收率、能耗与运行、兼容性方面差异较大。结合涪陵页岩气田增压运行实践,综合对比单站增压、区域增压、集中增压工艺优缺点,确定不同增压工艺的适用范围。
Pressure-boosting stimulation is an important means to improve oil recovery in shale gas wells.It can be divided into three patterns:single-station pressure-boosting,area pressure-boosting and centralized pressure-boosting.Different pressure-boosting stimulation patterns have great differences in project investment,ultimate recovery,energy consumption and operation,and compatibility.Combined with the pressure-boosting stimulation in Fuling shale gas field,the advantages and disadvantages of single-station pressure-boosting,area pressure-boosting and centralized pressure-boosting are comprehensively compared,to determine the applicability of different pressure-boosting stimulation treatments.
