【摘要】 综合利用地震、构造、露头、岩心及其分析化验等资料,对南翼山浅油藏构造特征进行分析。研究表明:南翼山构造形成始于N21,N21末成雏形,N22末已初步形成现今形态,N23末期最终定型,南翼山构造为典型的背斜构造,是由翼北2号、翼南2号断层相向逆冲形成,在此基础上主要形成了14条断裂,分别分析了各断裂的基本特征。裂缝以在压应力作用下形成的构造缝为主,裂缝的发育对该区油气的渗流有重要作用。更多还原

【Abstract】 The structural features of Nanyishan shallow oil pool is studied through analyzing various data such as seismic,structure,outcrop,core,test data and so on.The results show that the formation of Nanyishan structure started at N21,embryonic form(late N21),preliminarily formed present form(late N22),final deformation(late N23),Nanyishan structure as a typical anticline which thrusted by the fault of Yibei 2 and Yinan 2,analysis 14 faults features in the area.the main fracture is structure fracture caused by extrusion force,it plays an important role in seepage of oil and gas.更多还原
