阶梯水平井是指利用水平井钻井技术,在一个井眼中钻穿两个或者两个以上的水平段。利用阶梯水平井开发油藏,不仅节约了钻井成本而且增加了油井的泻油面积,进而提高了单井产量。侧钻作业的阶梯型水平井由于其独特的性质而慢慢得到了发展,本文结合新疆油田一口阶梯型侧钻水平井的施工经历,分析了阶梯型侧钻作业中的轨迹控制难点,分享了在侧钻作业中进行阶梯型作业的经验。 Stepped horizontal wells refers to the use of horizontal well drilling technology, drilling in a borehole through two or more horizontal sections. The use of a stepped horizontal well to develop a reservoir not only saves on drilling costs but also increases the area of ​​the oil-spilled oil, which in turn increases single-well production. Because of its unique properties, the horizontal well with sidetracking operation has been gradually developed. Based on the construction experience of a stepped horizontal well in Xinjiang Oilfield, the paper analyzes the difficulty of trajectory control in the operation of stepped sidetracking and shares Experience in ladder work in sidetracking operations.
