| 摘 要： | 为了解决煤层气地面钻井中钻井、固井及压裂造成的污染而产生的近井堵塞,采用水力喷射径向水平井技术,打通污染及堵塞带,沟通煤储层的裂缝系统。结果表明:将这一技术引入煤层气开发中,对因近井带污染等因素造成煤储层渗流通道不畅的煤层气井,即可以实现解堵作用,又可以沟通近井带以外的更多微裂隙及裂缝,降低流体流动摩阻,提高通道导流能力,达到气井增产的目的。该项工程工艺技术为煤层气地面钻井开发提供了一项新的增产措施和方法。

| Abstract: | In order to solve the pollution blockage caused by drilling,well cementation and fracturing, waterpower injector radial well technology is applied to break though the pollution and congestion belt,clear out the coal reservoir's crack.Results show that this technology can not only provides basis and guidance to de-plugging in the coal reservoir's impermeable channel,but also clear out more remote crack,reduce friction of fluid and improve the fracture flow capacity,and then achieve the purpose of gas well pr... |
