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 propping agent,to raise the success rate of deep well fracturing.This provided a powerful technical support for natural gas breakthrough of Yanchang gasfield.
