枣园油田枣43断块开发试验区油藏地质模型与开发效果

A GEOLOGICAL MODEL OF THE OIL RESERVOIR AND DEVELOPMENT EFFICIENCY OF ZAO 43 BLOCK IN ZAOYUAN OILFIELD

油藏地质模型是油藏描述综合研究成果的集中体现，建立科学、准确、精细油藏地质模型对于预测含油气有利区带、编制开发方案、选择注水方式及增产措施有着极为重要的意义，在综合分析枣园油田地层、构造、沉积、储层特征、流体性质等各项成果的基础上，本文提出了建立油藏地质模型的技术方法，并以枣４３断块先导开发试验区为例建立了油藏地质模型并总结了其主要地质特征，通过先导开发试验区前后的开发效果对比，证实所建模型具科学性、准确性和预测性，对开发枣园油田起到指导和预测作用。

Geological model of an oil reservoir is one of the synthetic scientific treaties of oil reser-voir,It is very important to built a scientific,actual,geological model of oil reservoir to pre-dict oil abundant area,select project developed to study choice production and injection be-havior and the field increase production.This paper gives technological methods of buildinggeological model of oil reservior on the basis of syntheticly analysing stratigraphy,structure,sedimentary microfaces,reservior feature,fluid properties and proposes a technologicalmethod of building geological model of the oil reservior Zao 43 Block is taken as an exampleand its main geolgical feature are sumrnarized.Through a comparison of the development re-sult before and after developrnent of a pilot area,it is proved that the model builted plays animportant role in guiding and forecasting to efficient development of Zaoyuan oil field.
