摘　　要：针对江汉油区不同特点的老油田,进行"内挖外扩"中的油藏精细描述技术的攻关研究,总结出了不同油藏类型的老油田进行"内挖外扩"时的油藏精细描述关键技术,其中复杂断块老油田内部开发调整(内挖)中的关键技术是精细地层对比、构造精细研究、单砂体沉积微相研究及油藏地质建模和数值模拟一体化的剩余油研究技术;中、低渗透构造-岩性老油田周缘滚动扩边增储(外扩)中的关键技术是将现有三维地震资料经二次处理,提高其分辨率、信噪比、成像精度的前提下,将测井、地震、生产测试等资料有机地结合起来,采用多种方法综合预测储层及其物性分布,评价滚动勘探开发潜力。In allusion to the characteristics of Jianghan Oilfield and the other oilfields with different properties,the fine reservoir description techniques of tapping the internal potential and expanding the external oil exploration for the old oilfields were studied,the key technologies of fine description of reservoirs of different old oilfields were summarized.The key technique of tapping the internal potential in the old complex fault oilfields included fine stratigraphic correlation,detailed study of structures,studying on sedimentary micro-facies of a single sand body,reservoir geological modeling and numerical simulation for remaining oil.The key techniques of expanding the external oil exploration in medium-low permeability structural-lithological old oilfields included that 3D seismic data were reprocessed so as to increase signal-to-noise ratio,resolution and image accuracy for the combination of logging,seismic,production and testing data to predict reservoir properties with multiple methods.The application of this technology achieves good result.
