In this paper,we discuss some key issues of the open hole sidetrack drilling:the optimal basis of the side tracking point;choosing the best sidetracking tool with the bottomhole mechanics analysis model;judgment basis on the well field after using rational parameters to drill into the new hole .The sidetrack drilling technique has been successfully applied to xx well,indicating that the above techniques are fully adapted to the sidetrack needs of the block.%本文浅议了裸眼侧钻过程的几个关键问题;侧钻点优选依据;结合井底力学分析模型,评价和优选出最佳的侧钻工具;使用合理参数侧钻进新井眼后现场判断依据等.在xx井裸眼侧钻成功应用,表明以上技术完全适应于该区块的侧钻需要.
