摘　　要：基于宁晋石盐草厂勘查区原探采结合井地质背景,分析定向水平井组堵塞原因,提出合理应用套管开窗侧钻技术对修治卤井、提高井组产能有重大作用。X10井与Y10井是一对水平连通井,因通道堵塞中断开采,分别对X10井及Y10井实施开窗侧钻、定向钻进后,最终井组连通,结果表明套管开窗侧钻技术费用较低,但是可以实现井组持续生产,提高了井组的产能。Based on the geological background of the original exploration and production combined well in the exploration area of shiyancaochang,Ningjin,this paper analyzes the blocking causes of directional horizontal well group,and puts forward that the rational application of casing windowing sidetracking technology plays an important role in repairing brine wells and improving the productivity of well group.X10 well and Y10 well are a pair of horizontal connected wells.The production is interrupted due to channel blockage.After windowing sidetracking and directional drilling are carried out for X10 well and Y10 well respectively,the final well group is connected.The results show that casing windowing sidetracking technology can achieve continuous production of the well group at a low cost and improve the productivity of the well group.
