摘　　要：跃进区块奥陶系油藏位于顺托果勒低隆北部,其所处的英买力突起-哈拉哈塘-阿克库勒凸起碳酸盐岩油藏整体含油。2013年在前期勘探、评价的基础上,对于油藏储层发育受控因素及储集体地震反射特征进行了分析和研究,认为Ⅰ类断裂控制了构造格局,Ⅱ类、Ⅲ类断裂控储控藏,且北北东向断裂岩溶发育程度较北北西向强,油气充注程度高;油藏最为有利的地震反射模式为“断裂+局部残丘高+串珠状反射(强振幅)”。The Ordovician reservoir in Yuejin block is located in the north of shuntuogol low uplift. The carbonate reservoir in Yingmaili uplift-Halahatang-akkule uplift contains oil as a whole. In 2013,based on the preliminary exploration and evaluation,the controlled factors of reservoir development and seismic reflection characteristics of reservoirs were analyzed and studied. It is considered that class Ⅰ faults control the structural pattern,class Ⅱ and class Ⅲ faults control reservoirs,and the karst development degree of NNE faults is stronger than that of NNW,with a high degree of oil and gas filling;The most favorable seismic reflection mode of the reservoir is "fault + local residual height +Beaded reflection(strong amplitude)".
