| 摘 要： | 该文在牛20、纯41、桩74、大芦湖等低渗透砂岩油藏地质综合研究的基础上,系统总结了胜利油区低渗透砂岩油藏储层非均质地质模型的研究内容和方法。该模型充分利用三维地震、地质、钻井、测井、测试等资料,以定量研究为主要方法,以地层模型、构造模型和储层模型研究为基础。裂缝模型研究是关键,主要包括野外和岩心裂缝研究、测井方法研究裂缝密度、古构造应力场模拟方法预测裂缝走向、现今应力场模拟方法研究裂缝的连通性及分析压裂裂缝的展布方向和储层裂缝对油田开发的影响等。储层非均质地质模型研究主要包括测井资料解释模型的建立、层间非均质研究、层内非均质研究和平面非均质研究。该模型在胜利油区应用效果良好。

| Abstract: | Based on the comprehensive geological study of Niu-20, Chun-41, Zhuang-74 and Daluhu low-permeability sandstone oil pools, the research content and method of the geological model on the reservoir heterogeneity of low-permeability sendstone oil pools in Shengli oil district were sumarized systematically in this paper. This modol takes full use of 3-D seismic, geologic, drilling, logging and testing data. Quantitative research is the major method, and the study of stratigraphic, structural and reservoir models is the base. The study of fracture models is the key, which including the study of field and core fractures, fracture density research by logging, fracture trend prediction by paleo-tectonic stress field simulation, fracture connectivity research by modern stress field simulation and the effect analysis of fracture direction and resservoir fractures on oilfield development. The study of the geological model on reservoir heterogeneity mainly includes the establishment of the logging data interpretation model and the study of interlayer, in-trastratal and plane heterogeneity. The model has good application effects in Shengli oil district. |
