摘要
在分析了煤层气的储存特征的基础上,进一步分析了在钻井过程中钻井压力及钻井液对储层的伤害机理,进而在钻井工艺及钻井液两方面对储层保护进行了分析总结。
On the basis of analysis on the characteristics of CBM reservoirs, this paper further analyzes the damage mechanism on CBM reservoirs caused by drilling pressure and drilling fluid during the drilling process, and finally works out a conclusion on reservoir protection in aspects of drilling technology and drilling fluid.
