摘要 面120区位于八面河油田西南端,主要含油层系为下第三系沙河街组沙三段与沙四段。区内沙三段与沙四段呈不整合接触,由于主要含油层组集中,在油藏开发初期,地层对比和划分存在一些问题。经过重新进行地层精细对比划分,新发现一套沙三中油层,使该区储量、产量大幅度增加,取得了良好的油藏开发效果。 Mian-120 Area is located on the south-west end of Bamianhe Oilfield. the main reservoirs include Sha-3 Zone and Sha-4 Zone of Shahejie formation of palaeogene system. The Sha-4 Zone is contacted discordantly with Sha-3 Zone. Some problems existed in stratigraphical correlation and division works because of the centralized oil formation at the early stage of reservoir development. A series of new oil layers in San-3 Zones,which have made the oil reserves and oil productions in Mian-120 Area increased through fine stratigraphical correlation and division works again. As a result,a good development effect has gained in Mian-120 Area.
