相控建模技术在濮城油田精细油藏描述中的应用

Application of modeling by control of reservoir facies for fine scale reservoir description of Pucheng Oilfield

针对濮城油田高含水开发后期难度大、储层非均质性严重的特点,以濮城油田沙一段为例,阐述了相控建模技术在精细油藏描述中的应用。为了精确描述储集层物性及其展布特征,综合应用地震、测井、地质和岩心分析资料,分析和研究了该油藏的构造特点、沉积相体系和储层物性参数,最后运用建模软件建立了研究区构造模型、沉积微相模型以及微相控制下的储集层属性模型,为油藏的开发调整、挖掘剩余油潜力提供了依据。

It has characteristics of numerous difficulties in waterflooding development and severe heterogeneity of for- mation at a later stage of high water cut of Pucheng Oilfield. Taking the Es1 reservoir of Pucheng Oilfield as example, it was illuminated how to use the modeling by control of reservior facies in reservoir description. In order to accurately describe the reservoir properties and their distribution features, the structural feature, sedimentary facies sequence, and physical pa- rameters of the reservoir were analyzed and researched by the modeling technology on the base of a integrated application of data of drilling, seismic, log interpretation and core analysis, etc. And structural model, sedimentary microfacies model, and physical parameter model by control of microfacies were finally established through the modeling technology. For adjustment for development of the oilfield and making full use of the remaining oil, these accurate data were provided.
