摘要
本文主要介绍了以WH-B型煤层气绳索取心工具为主的煤层气取心工艺,在大量实践基础上,总结出低钻压、低转速、低排量的钻井技术参数,能够满足大部分煤层气井的取心要求。同时介绍了该技术在山西沁水地区施工中的应用及效果。
This paper introduces the WH-B-type wire line coring tools based CBM coring process. Based on a lot of practice, the paper finds out that low WOB, low-speed, low-emission drilling technology parameters which meet the coring requirements of large part of CBM well, also introduced the application and effect of construction technology in Qinshui area.
