近年来,各大油田均进行了分支井施工技术的攻关研究,胜利油田已经能够独立进行分支井的工程设计和分支水平井的施工方案,并研制出系列分支井专用工具仪器。本文探讨了多分支井的分类、特点、钻井技术关键及钻井方法,并以河3-支平1双分支井钻井技术为例进行了论述,从而提高分支井的经济效益,并最终促进分支井钻井技术的进一步发展。
In recent years, major oilfields have conducted research on the branch well construction technology. The Shengli Oilfield has been able to independently carry out branch well engineering design and branch horizontal well construction program, and developed a series of branch well-specific tools and instruments. In this paper, the classification, characteristics, key drilling techniques and drilling methods of multi-branch wells are discussed. The drilling technology of Shuang-Zhiping 1 double-branch well is taken as an example to improve the economic benefits of branch wells and finally to promote branch wells Drilling technology further development.
