Study of finite element on egfects of faults on ground stress field

SHEN Hai-chao,CHENG Yuan-fang,WANG Jing-yin,ZHAO Yi-zhong (Petroleum Engineering Institute of China University of Petroleum,Dongying 257061,China)  
Fault stress field study is one of problems in oil and gas field development.The effect rules of faults on ground stress field are studied by using finite element method,and several factors are considered including mechanical property of surrounding rock of both side of faults(elastic modeling quantity,Poisson ratio,etc.),mechanical property of faulted medium,fault geometry and edge conditions.The results indicate that,these factors have different influences on stress field distribution near faults.Their changes all make ground stress degree and direction varied.This study result provides reference for ground stress analysis in fault development zone of oilfield.
