超短半径侧钻水平井技术在外围油田的应用

Application of Ultrashort Radius Sidetrack Horizontal Well Drilling Technique in Peripheral Oilfields

利用大修设备对超短半径侧钻水平井技术,对最初的悬挂筛管完井方式进行改进,用较简单、经济的方法实现完井管柱对钻遇泥岩段的有效封堵,解决泥岩水化产物造成的斜后泥岩层、坍塌和后续生产频繁卡泵问题,取得了较好的应用效果。

Ultrashort Radius Sidetrack Horizontal Well Drilling Technique is continuously improved using overhaul equipment. The well completion method of hanging screen liner was improved by using a simple and economic method, and completion pipe string ef- fectively plugs the drilled mudstone, which solves the collapse of mudstone layer caused by shale hydration and the frequent stuck pump in follow-up production. The ultrashort radius sidetrack horizontal well drilling technique has achieved good application results.
