Through a series of basic structural geological work,the fault barrier of reservoirs and theirs structural locations were described in this area,and it was illustrated that the reservoirs along faults were important targets for reservoir adjustment and potential exploitation because its high.

文中通过一系列基础构造地质工作,描述了该区油藏的断裂遮挡及其构造位置;阐明了油藏沿断裂一带构造部位高,压力保持程度低,油井总体注水受效差,是该区油藏调整挖潜的重要部位;分析并指出了该区逆掩断裂形成的油藏断裂掩覆含油带,断裂面处于低倾角向上变陡转折部位,下盘受断裂遮挡控制,具明显推复挤压形态,其压应力集中,单井产油量高,是该区油藏断裂扩边主要潜力区。
