随机建模技术在温西三区块油藏描述中的应用
|
摘要
针对温米油田温西三区块高含水开发后期开发难度大,储层非均质性认识不清等问题,以区块三间房组油藏为例,开展了储层地质建模研究。结合钻井、地震、测井解释、岩心分析等资料,运用相控随机建模技术,分析和研究了区块的构造、岩相分布及储层物性特征,精细构建了区块构造模型、岩相模型及储层物性参数模型,全面描述了储层的非均质特征,为油藏数值模拟提供了真实、可靠的三维数据体,为后续开发调整及剩余油挖潜提供了地质依据。
The block 3 of Western Wenmi oilfield has the characteristics of knotty development in the stage of high water cut and strong heterogeneity formation.Taking J_2s reservoir in the block for example,the research of reservoir geological modeling is conducted.The structural feature,lithology facies disribution and property of the reservoir are analyzed and researched by use of the phase control modeling technology on the base of data of drilling,seismic,log interpretation and core analysis etc.And then,structural model,lithology facies model and physical parameter model on researched block are established accurately,the heterogeneity of the formation is described roundly.It provides accurate and credible data set for numerical modeling,geology foundation for the following development adjustment and making full use of the potential of the remaining oil.
