| 中文摘要:煤田钻孔终孔测井前大幅度调整泥浆性能，用稀泥浆循环冲孔，破坏了原孔壁的稳定性，引发破碎岩石掉块，造成测井探管遇卡，如果处理方法不当将造成事故的复杂化。通过实例叙述了探管遇卡的经过，分析了遇卡原因，从处理方案的确定到处理过程，总结事故处理经验与教训，为今后在施工中遇到类似情况提供可借鉴的经验。 |

| Abstract:The mud property is largely adjusted before the hole termination in coalfield drilling, the stability of hole wall was destructed by the changed mud property, which leads to fractured rock falling and logging tube blocking; and improper treatment would make the accident even more complicated. The causes of blocking were analyzed with the treatment experience and lessons. |
