| 中文摘要:裸眼侧钻技术是最常用的钻井工艺技术之一，但若对侧钻技术不熟悉或侧钻方法单一，往往导致侧钻周期长、损失井段多、工具和仪器损耗大，甚至造成侧钻失败。分析了裸眼侧钻的几个关键问题；给出了选择侧钻点的依据；结合井底力学分析模型，评价和优选出最佳的侧钻工具；在对比控压和控时两种侧钻方式优缺点的基础上，绘制出侧钻方式选择图，便于施工人员灵活选择侧钻工艺。用一口井的侧钻施工实例，阐述了上述关键技术的具体应用情况。 |

| Abstract:Sidetracking in open hole is one of the most popular drilling technologies. Unknowing sidetracking or only with single sidetracking method, the construction time would be longer, more well sections would be lost with tools and instrument loss, even with failure. Some key problems of sidetracking are studied and discussed in this paper; principles of kick-off point are given and the evaluation of tools and control drilling by time or weight on bit are brought forward. In addition, sidetracking in a well is taken as an example to describe the technologies. |
