煤层气井储层保护钻井工艺

Study on drilling technology beneficial to coalbed protection

    摘要
  • 摘要: 采用合适的钻井工艺是保护煤层气储层免受伤害, 从而提高煤层气井单井产量的关键环节。煤层气井储层保护钻井工艺包括低压钻井工艺、常规屏蔽暂堵钻井工艺和边钻边完井工艺。本文在介绍这些工艺的基础上, 分析了煤层气储层伤害的机理, 提出了相应的防护措施。

     

    Abstract: To select an appropriate drilling technology beneficial to reservoir protection is a key step to increase the production capability of single CBM well.Some of these drilling technologies,including low-presseure drilling,temporary plugging,completing while drilling operation,are studied,as well as the properties of them are analyzed.
