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 。
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.
