| 中文摘要:总结了桂中-南盘江地区页岩气调查黔水地1井在钻进过程中出现的严重井漏、卡埋钻、起下钻或通井遇阻等技术难点及相应的处理措施。由于钻遇的地层较为复杂，因此综合采取了回填粘土、商砼封堵、顶漏钻进、岩屑打捞、空气钻进、跟管钻进、套管封隔等多种措施进行处理；此外，结合实际工程应用提出了针对该复杂地层的多种钻井液配方，均取得了一定的效果。处理技术难点的过程中所积累的钻探技术和钻井液技术的优化经验能够为日后黔西南复杂构造区页岩气勘探的实施提供一定的参考依据。 |

| Abstract:The technical difficulties， including serious leakage， stuck drilling， tripping， obstruction in wellbore clean-up， and the corresponding treatment measures in regard to drilling of the Well Qianshuidi-1 of shale gas exploration in the central Guizhong-Nanpanjiang area are summarized. Due to the complex formations encountered， various measures such as backfilling of clay， commercial concrete plugging， drilling blind against leakage， cuttings bailing， air drilling， drilling with casing， sealing with casing， and other measures had been adopted for treatment. In addition， in view of the actual engineering situation， various drilling fluid formulations were used for this complex formation， and they all achieved certain effects. The drilling technology and drilling fluid technology optimization experience accumulated in this process can provide some reference for the future implementation of shale gas exploration technology in the complex structural area in Southwestern Guizhou. |
