| 摘 要： | 随着岩心钻探深度的不断加大，使得起下钻等辅助时间增多，提高单回次钻进效率势在必行。在钻井设备没有大范围更新的前提下，针对宁晋-辛集地区盐岩取心钻探的难点，开展了井身结构优化、不取心井段快速钻进、盐水钻井液体系及盐岩层安全取心等配套技术研究，并在现场实践中得到了成功应用，为该区进行盐岩井钻探施工提供借鉴。

| Abstract: | Due to the core drilling depth increasing with more auxiliary work time, improvement of round trip efficiency is imperative.Without large scale of drilling equipments renewal, according to the difficulties in salt rock coring in Ningjin-Xinji exploration area, the supporting research was made on optimization of well program, rapid drilling in non coring sec-tion, salt water drilling fluid system and safe coring in salt rock layer, which was successfully applied in the field practice. |
