摘要
本文根据钻直井的纠斜技术和定向井侧钻技术，研究、总结了在裸眼井中的三种侧钻形式，即钟摆钻具侧钻、磨铣落鱼侧钻、井下动力钻具侧钻技术。运用这些技术成功地在四川气田Ｓ２４井、Ｗ２井、Ｚ４井进行了侧钻实践，解除了这些井的井下事故。
According to hole straightening technique in drilling straight wells and sidetracking technique in drilling directional well,this paper proposes 3 lateral drilling methods in open holes,which are sidetracking by pendulum assembly,sidetracking by milling fish and sidetracking by downhole assembly.These techniques are used successfully in S24,W2 and Z4 well of Sichuan gas field to remove the downhole accidents.
