摘要： 本文阐述了不同组合形式断层的主要特征;通过对断层应力场的数值模拟,总结了断层应力效应以及对裂缝系统形成的影响;指出了断层附近裂缝发育的一般规律。为裂缝性储层评价,合理布井勘探裂缝性油气藏提出参考性建议。

Abstract: This paper presents the principal characteristics of faults in various assemblages. Through the numerical simulation of faulting stress field , the stresses and their effects of forming fracture systems are summarized, pointing out generally regular Patterns for developed fractured near the faults. Finally, some reference suggestions for evaluation of fractured reservoir and reasonable location of wells to explore oil—bearing fractured reservoirs are presented in this paper.
