摘　　要：复杂小断块油田具有面积小、断层发育、构造破碎、油水关系复杂以及开发后期剩余油分布复杂等特点。通过对杨家坝油田资料的分析,提出了水淹层测井解释、矿场测试资料分析、动态分析以及数值模拟等多种剩余油研究方法。平面上,剩余油主要富集在滩坝、河口砂坝微相中,其他砂体剩余油分布较少;纵向上,剩余油主要分布在含油面积较大的主力油层、漏射的非主力油层以及厚油层的顶部。The small complex block oilfields are characterized by small area,abundance faults,broken structure,complex oil-water relationship,and the complicated distribution of remaining oil in the late production period.Based on the analysis of Yangjiaba Oilfield,a series of methods of remaining oil research were raised,including log interpretation of swept layer,field testing,dynamic analysis,numerical simulation,and so on.Laterally,the remaining oil normally enriches in beach bar and mouth bar microfacies.Vertically,the remaining oil chiefly distributes in main layer with large oil-bearing area,lost non-essential layer,and top part of thick reservoir.
