摘　　要：社会发展对能源需求越来越大,煤层气作为一种新能源,具有广阔的发展前景。施工操作人员通过施工煤层气参数井,获取煤层内部储气量数据,从而确定储量。实际钻井施工作业中,对煤层气本身质量要求相对较高,钻井液、质量等都有一定的要求,且施工难度相对较大。借助相关设备和先进技术,钻井参数能确保钻井质量,同时,根据不同地段选择钻井液类别,一定程度上可以保护煤储层。论文主要是探讨煤层气参数井钻井施工中的难点以及相应的解决措施。With the development of society, the demand for energy is increasing. As a new energy, coalbed methane has a broad development prospect. Through the construction of coalbed methane parameter wells, the construction operators can obtain the data of gas storage in the coal seam, and then determine the reserves. In the actual drilling operation, the quality requirements of coalbed methane itself are relatively high, the drilling fluid, quality and so on have certain requirements, and the construction is relatively difficult. With the help of relevant equipment and advanced technology, the drilling parameters can ensure the drilling quality. At the same time, the selection of drilling fluid types according to different sections can protect the coal reservoir to a certain extent. This paper mainly discusses the difficulties in the drilling construction of coalbed methane parameter wells and the corresponding solutions.
