一种新型人工井底工艺管柱

A New Type Tool of Establishing Artificial Bottom of a Well

针对苏里格气田合作区块建立的人工井底注灰方式存在"插旗杆"的问题,设计了一种新型的人工井底工艺管柱。通过使用Y111型封隔器及液压丢手接头工具组合,下至设计位置后下压管柱坐封封隔器,投球憋压实现液压丢手接头丢开,建立人工井底。该新型人工井底管柱组合在苏里格地区成功应用3口井,为苏里格气田老井措施改造提供了新的技术手段。

Operators in the cooperation blocks of Sulige Gas field commonly adopt cement injection method,so on artificial down-hole tool string is established.This method often causes inserting flagpole problems.In order to work out other technical plan to establish artificial down-hole tool string,a design of new tubing string in made to establish artificial bottom.After running Y111 type packer and the combination of hydraulic releasing tool and subs in the targeted place,a new tubing string was run down to set the packers.Ball sealers and pressure realizes the release of the subs of hydraulic releasing tool and establish artificial bottom of a well.The new string combina-tion tool has been successfully applied in three wells in Sulige gas field,providing a new technical method to stimulate the old wells of Sulige gas field.
