煤层气钻井工艺技术研究

The Second Prospecting Team of Shandong Coal Geology Bureau

目前,在煤层气钻井开采过程中基本上采用的是石油钻井工艺,但是由于煤层气依附于煤层,其在物理力学性质及储存方式上与常规油气层并不相同,这就决定了煤层气钻井工艺技术具有与常规石油开采不同的特殊性。本文拟对煤层气钻井工艺技术进行初步探讨,以期为钻井施工提供有益参考。

At present, in the process of mining CBM well drilling are basically drilling technology, but because the combed methane in the attachment to coal, stored and physical and mechanical properties with conventional reservoirs are not identical, this determines the coalbed methane drilling technology with conventional petroleum exploitation of different particularity. The thesis CBM drilling technology were discussed, in order to provide useful reference for drilling.
