摘　　要：TK1202井是部署在塔河油田AD4井区缝洞发育带上的一口开发井。常规四开井身结构,三开钻进中遇设计外盐层。在不更改井身结构的情况下,如何钻穿盐膏层完成设计井深,是本井的创新。文章着重介绍有10 m盐层的三开井段钻井技术及工艺。Well TK1202 in AD4 wellblock of Tahe oilfield was a development well drilled in fracture -vug zone with the design depth of 6 670 m （ finished drilling with depth of 138 m from Middle Ordovieian） and the well configuration of the four times conventional drilling. During the third drilling, it met salt layer that had not been designed. The innovation of the well is to implement the planned design depth by drilling through the salt layer without changing the well configuration. The drilling technology for drilling the interval of the third drilling at 10 meters salt layer is introduced emphatically.
