渝东南地区彭水区块前期钻井过程中表现出上部地层可钻性差，机械钻速低；二叠系、三叠系地层灰岩缝洞发育，地层漏失严重；志留系韩家店组以下地层倾角大，地层造斜能力强，井斜控制难等特点。通过对井身结构、钻井方式等的研究与优化设计以及在现场的应用，初步确定了该区块页岩气水平井钻井技术方案，为实施页岩气水平井开发奠定了基础。

In the early well drilling process of Pengshui block, southeast Chongqing, it occurs poor drill ability and low ROP in up-per formation, limestone cave development and serious formation leakage in Permian and Triassic. Aiming at characteristics, such as large stratigraphic dip, good formation deflecting ability and difficult control of deviation in Hanjiadian formation of Silurian sys-tem, through study and optimal design of well bore configuration and drilling mode, and based on field application, this paper pre-liminary determined technology solutions of horizontal wells in Pengshui shale gas, thereby providing basis for carrying out develop-ment of this area.
