摘要
水平井封隔器分段压裂技术对川西难动用储层具有较强的针对性,通过对裂缝条数、裂缝半长、长度组合等参数进行优选,得到了新场沙溪庙组气藏水平井的压裂施工优选参数;并研制了适合于套管井的国产化的封隔器组合,采用封隔器配合喷砂滑套进行分段压裂改造。水平井封隔器分段压裂技术在XS21井成功应用,取得了很好的增产效果。
Segregated fracturing technology of horizontal well have a strong pertinence to difficult-to-produce reserves in west of Sichuan.Through the optimization of fractures number,half-length of fracture,length combination,etc,we get the optimization fracturing parameter of horizontal wells in Shaximiao formation of Xinchang gas field and developed made in China packer combination suitable in casing well,which applied to carry on segregated fracturing with packers.This technology is applied successfully in XS21 and in-crease production.
