摘要:The analysis of the major domestic and overseas coal countries was based on CBM resources, it was found that Chinese CBM development foreground is very considerable, the development and utilization of coal bed methane (CBM) can greatly improve our country's energy structure, to a certain extent, also solve the en- ergy supply, but the unreasonable drilling and well completion technology to use, which will cause the damage to formation, and the influence of reservoir gas production. Therefore, aim at reservoir problems, and the pa- per put forward the adaptive CBM reservoir drilling technology and completion way, and emphatically intro- duces various drilling technology and coalbed methane well completion technology, the conclusion of the analy- sis shows that the cooperation to use the underbalanced drilling technologies and well completion technology ( open-hole completion, power cave completion and casing perforating fracturing) , which could support devel- opment of CBM reservoir, help to reduce the damage, thus improve the quantity of CBM.%在分析国内外主要煤国煤层气资源量基础上,可看出中国的煤层气储存量非常丰富,虽然煤层气的开发利用能大大改善我国能源结构,在一定程度上解决能源供给不足,但是不合理的煤层气井钻、完井方式会对储层造成伤害,影响产气量。因此,针对储层的伤害问题,提出了适应煤层气储层的钻井工艺和完井方式,并着重介绍了各种煤层气井钻井工艺和完井技术,分析结果说明:采用欠/微平衡钻井工艺与裸眼完井、动力洞穴完井和套管射孔压裂完井等完井技术配套开发煤层气,有利于减小对储层的伤害,从而提高采气量。
