浅析煤层 砂岩层压裂前后的地应力状态

Preliminary analysis on stress state in front of and after fracturing of coal seam and sandstone

    摘要
  • 摘要: 介绍了地下两种物理性质不同的目的层,通过压裂前后地应力测量的成果图件,反映了人工裂隙在不同目的层中延伸方式和影响范围的差易,这种研究方法有可能为煤层气(油、气)开采时井位设计提供一些地质依据。

     

    Abstract: The maps of stress measurements for two physically different target seams in front and after fracturing are presented.The maps show differences of extending ways and influence scopes of artificial fractures in two different seams.This method provides some useful geological information for well design in coalbed methane (oil,gas) development.
