延长气田深井压裂工艺技术改进及应用

摘要

针对延长气藏埋藏深,深井压裂施工压力大,压裂成功率低的特点,结合多口井的压裂实践,从井口装置、压裂管柱、封隔器、压裂液、支撑剂等方面采取措施,提高了深井压裂施工的成功率,为延长石油在天然气方面的突破提供了有力的技术支撑。%According to Yanchang gas reservoirs having deep buried,high fracturing pressure,and low fracturing success rate,combined with fracturing practices of multiple wells,measures were taken from wellhead device,fracturing tubing,packer,fracturing fluid,and pr
