新疆油田LuHW301Z双分支水平井钻井技术

Double Branches Horizontal Well Drilling Technology Used on The LuHW301Z Well in Xinjiang Oilfield

分支井技术是提高采收率及油气开采经济效益的有效技术手段。新疆油田应用自主研发的分支井钻井完井工具,在陆梁油田成功钻成了TAML 4级难度的LuHW301Z双分支水平井。以该分支井钻井完井工具和LuHW301Z井为例,介绍了TAML 4级分支井钻井、完井的技术关键,分支井设计及施工的关键技术环节,为今后国内油田实施和推广TAML 4级分支井技术提供了借鉴,积累了经验。

Multilateral wells are effective to enhance oil recovery and improve petroleum exploitation economic benefits. Based on the successful case of TAML level 4 dual-lateral well LHW301Z in Xinjiang Oilfield which used the multilateral technology with independent intellectual property of Karamay DTRI, this paper introduces the key drilling and completion technology, drilling program and operation procedures of TAML level 4 multilateral well, which will provide experiences for application of TAML level 4 multilateral technology in other oilfields.
