| 摘 要： | 在硬、脆、碎地层取样过程中,使用常规取样钻具取样常会出现取心率低、岩心品质差的现象,为此特别设计了密闭胶体取样工具。在内蒙古野外现场实践过程中取心率提高至85%以上,获得了良好的效果。介绍了钻具的结构和设计原理,及其野外生产试验效果。

| Abstract: | In order to solve the problems of difficult coring operation in the hard and broken ground with bad quality of coal core and low core recovery, sealed coring tools were used, which could basically meet the coring requirement of coal-bed gas well. Configuration features and work principles of sealed coring tools were introduced in this paper. The field practice in Inner Mongolia showed that high core recovery （more than 85% ）could be obtained by using sealed coring tools. |
