摘　　要：塔河油田超深探井AD7井钻遇在塔河工区所有复杂地层。本文通过调整合理的钻井参数、制定相应的技术措施以及优化泥浆性能保证了上部井段的快速钻进,实现了无阻卡起下钻,顺利穿过易塌、易卡地层,保证井身质量,并在该区用PDC钻头快速安全钻穿二叠系英安岩脆性地层,全井测井、下套管、固井顺利,小井眼取芯收获率达92%以上。The ultra-deep exploratory well AD7 drill all the complex formation of Tahe oilfield. In this paper, it adjusts the drilling parameters, develop appropriate technical measures, optimize the mud properties ensure the rapid drilling of the upper wells, the unimpeded card tripping, ensure a good quality of casing. And quickly and safely drill wear Permian by PDC bits, Logging, casing and cementing are smoothly, Slim hole core harvest rate is more than 92%.
