摘要
在煤层气资源勘探和开发的过程中,通过煤层气参数井能够了解研究区的地质特征、煤层气储层特征与含气性分布状况,对评价煤层气勘探前景、制定科学的开采方案、保障开采过程的顺利进行起到重要的作用。文章结合尔林兔勘查区三口煤层气参数井的钻探施工实例,从钻井施工设备、钻具组合、钻井结构、防斜措施等工艺技术进行了简要的探讨,提出一些施工过程中应注意的事项,为今后的煤层气参数井钻井施工提供指导和借鉴。
In the process of exploration and development of coalbed methane resources,through coalbed methane parameter wells,the geological characteristics,coalbed methane reservoir characteristics and gas-bearing distribution in the redearch area can be understood,which plays an important role in evaluating the prospects of coalbed methane exploration,formulating scientific mining plans and ensuring the smooth development of the mining process.Combining with the drilling construction examples of three coalbed methane parameter wells in Erlintu exploration area,the technologies of drilling construction equipment,drilling tool assembly,drilling structure and deviation prevention measures were discussed,and some matters needing attention in the construction process were put forward,which can provide guidance and reference for the drilling construction of coalbed methane parameter wells.
