摘要
应力敏感性使得低渗透油藏在开发过程中地应力变化比较明显。考虑储层渗流场与应力场的耦合作用,揭示了注水井及采油井附近围岩体孔隙压力随注采压差的动态演化规律。
Geo-stress evolution in the process of oil filed development can directly influence well-bore stability. Therefore,it is significant to strengthen the research of the evolution rule for well drilling and casing protection. Considering the interaction between reservoir seepage and stress fields,disclosure the dynamic change regulation of pore pressure and geo-stress of surrounding rock nearby the injection and production well.
