according to the former research results, by the method of reservoir correlation, that is, by combining sedimentary cycle correlation, hierarchical control and discriminating different sedimentary facies association, the-type oil reservoir in the research target was divided 28 sedimentary units and sedimentary microfacies mode of-type oil reservoir was built . in the light of sedimentary development characteristics,-type oil reservoir was divided into 5 sorts again 根據(jù)前人的研究成果,利用“旋回對(duì)比,分級(jí)控制,不同相帶區(qū)別對(duì)待”油層對(duì)比方法,將研究區(qū)二類油層劃分為28個(gè)沉積單元,建立了二類油層沉積微相模式,按沉積發(fā)育特征,將研究區(qū)二類油層分為5種類型。
