| 摘 要： | 煤层气是一种新型接替能源,世界上很多国家都已投入煤层气的勘探和开发,其中美国、加拿大、澳大利亚的煤层气产业发展迅速。我国煤层气储存量非常丰富,在一定程度上能解决能源供给不足,但是我国煤层气储层特征相对复杂,勘探与开发难度颇大,不合理的煤层气井钻、完井方式会对储层造成伤害,影响煤层气的产出。针对上述问题,提出了适应我国绝大多数煤层气储层的钻井工艺和完井方式,着重介绍各种煤层气井钻井工艺和完井技术。分析结果表明: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,有利于减小对储层基质、割理的伤害,提高采气量。最后对我国煤层气的勘探开发前景进行了展望。
