摘要
结合新疆煤层气勘查项目施工实践,对煤层气参数井、排采井的不同施工方式,从钻井时间、预算标准、孔内事故和相关规范要求等方面进行讨论,提出针对不同地质、市场条件下煤层气钻井施工的建议方案。建议在目的煤层多、取心段长的钻孔,将参数井与排采试验井分开施工;在煤炭控制程度高、目的煤层少、取心段短区域,可以合并施工。
Combining with the paper analyses different drilling construction practice of CBM exploration project in Xinjiang region, the methods of CBM parameter well and pre-production well. The aspects of discussion includes the drilling time, budget standard, drilling accidents and related regulations, etc. According to different geological and market conditions, the paper puts forward proposals for coalbed methane drilling construction. It also proposes that the separate construction scheme about coalbed meth- ane parameter well and pre-production well in multiple coal seam and longer coring drilling project, and in contrast if the integrative construction scheme in high drilling project. degree of coal exploration and shorter coring
