【摘要】 断裂是黄骅坳陷北大港潜山构造带的主要构造特征。为了清楚地认识港中油田复杂断裂特征,分析不同级次断层对剩余油的控制作用,本文依据高精度地震解释资料,采用井震结合的方法,分析了港中复杂断块油气田不同级次断层的断裂特征,并总结出了逆牵引背斜构造样式等6种断裂组合样式。在研究断层对剩余油分布的控制作用基础上,总结了近平行、斜交断层夹持及断层拐弯处等6种断层控制剩余油分布模式,丰富了复杂断块油田剩余油分布理论。更多还原

【Abstract】 Fault is the main structural feather of BeiDaGang buried- hill tectonic belt in HuangHua depression. In order to clearly recognition the characteristics of complex fracture in Gangzhong oilfield and analyze the control action of different order faults to remaining oil,this article bases on high accuray seismic data in combination of well data with seismic data,thus collated afresh the fracture characteristics of different order fault in GangZhong complex fault- block oilfield and six fault combination styles such as antithetic drag anticline and the like are sumaried. On the basis of the control action of fault to distribution of remaining oil,six oil control models of faults are put forward,such as the model of oil control in fairy straight lines,inclined fault clamping,and at the corner of fault,enrich the thesis with respect to the distribution of remaining oil in complex fault block oilfield.更多还原
