国内第一口分支水平井钻井技术

Drilling Techniques of the First Domestic Lateral Horizontal Well

胜利油田为适应提高勘探开发总体效益和开发老油田剩余油资源及特殊油藏的需要 ,试验完成了国内首口分支水平井——桩 1-支平 1井 ,探索了适合胜利油田钻井工艺技术特点和装备水平的分支水平井钻井完井技术。重点讨论了分支水平井工程设计、钻井工艺、定向回接。

In order to improve the overall exploration & development profit and develop the retained oil in old oilfields and the special reservoir, the first domestic lateral horizontal well-Zhuang1-Zhiping1Well was experimentally finished in Shengli Oilfield. The drilling and completion techniques, which fit with the drilling technologies and equipment condition in Shengli Oilfield, are explored. Some techniques of lateral horizontal wells, such as engineering design, drilling technique, directional back jointing, drilling fluids and cementing using plastic cement, are mainly discussed.
