摘　　要：为了准确模拟和预测裂缝性潜山油藏的油水运动规律,以渤海海域J油田为例,综合岩心、测井、地质、地震及生产测试等多方面资料,分步建立了双重介质储集层的三维地质模型并开展了数值模拟研究。首先建立起工区构造模型,并建立了基质单元属性模型,然后利用岩心成像测井裂缝描述成果,以地震叠前属性反演成果为约束条件,模拟建立了裂缝分布网络模型,最后将基质属性和裂缝分布网络模型有机结合并建立了双重介质储集层三维地质模型。在此基础上,开展研究区历史拟合研究。结果表明:1采用该模型能够很好地表征裂缝性变质岩储层的渗流介质特征,数值模拟区块和单井历史拟合符合率高达90%;2潜山油藏开发可以划分为裂缝主要供油阶段、裂缝和基质同时供油阶段、基质主要供油阶段三个阶段;3运用定性-定量相结合方法研究得出的剩余油分布,能够客观地反映裂缝及基质系统对流体流动规律的影响,有力地指导了研究区下一步调整措施的实施。In order to guide oilfield subsequent adjustment measures,it＇s important to simulate and predict accurately the oil-water distribution relationships in buried hill fractured reservoir.The 3Dgeological model of dual porosity reservoir in the J oilfield,a typical metamorphic rock buried hill reservoir in Bohai Bay,is built step by step based on the detailed core observation and employing core data,log data,geological data,seismic data and production test data.Firstly,the structure model is built.Secondly,the fracture distribution model is established applying the results of the seismic property analysis and the core-FMI fracture description.Thirdly,the 3-D integrated geological model of the dual porosity reservoirs is set up by combining the matrix property models with the fracture distribution model and applying the filtration theory between matrix and fractures.On this basis,the study of simulation and history matching are carried out.The results show that：1the seepage features of buried hill fractured reservoir can be well characterized by applying this model.The compliance rate between history matching and measured data is up to 90%.2The development of buried hills reservoir can be divided into three stages;3The remaining oil distribution by simulation can objectively reflect the impact of fracture and matrix on dual porosity media fluid flow and which can effectively guide the next adjustment plan for study area.
