【摘要】 复杂断块油藏是我国油气田开发中重要的油藏类型之一,其构造复杂,隐蔽性强,描述比较困难。对留西油田属于复杂断块油田,根据其断层发育,构造复杂,非均质性强等特点,采用Petrel软件,以三维地震解释为基础,充分利用钻井、测井、地层对比等数据,分析断层在空间的相互切割关系,建立了三维构造模型,并利用断点数据对模型进行质量校正,更加精确地反应了研究区的构造特征。同时,应用"相控克里金储层参数建模软件",建立在沉积相和流体相约束下的储层参数模型。由于采用相控～克里金建模技术,通过合理添加虚拟井点,弥补了因实际井点不足,造成的预测井间储层参数时出现的误差,提高了储层模型的精度和准确性,反映了油藏非均质性特点和油水分布规律,为精细油藏数值模拟等后续油藏研究奠定了基础。更多还原

【Abstract】 Complex fault oil field is an important kind of oil field in development of Chinese oil field,the structure of this kind of reservoir is complicated with strong elusiveness and is difficult to describe.Liuxi oilfield belongs to complex fault block reservoir because of its characteristics such as highly developing faults,complicated structures and obvious heterogeneity.The software Petrel is used to build its three-dimensional structure model based on 3D seismic data interpretation and the combination with drilling,logging and stratigraphic correlation data,to analysis the crosscutting relationship of the faults on scope,which make the structure feature of the study area more accurately.By use of facies-controlled-kriging reservoir parameters modeling software and facies-controlled-kriging modeling technology,the reservoir parameters model is constructed under the constraints of sedimentary facies and fluid facies.Through using of faciescontrolld-kriging modeling technology,adding virtual wells and retrieving the error when predicting the interwell reservoir parameters caused by less of actual well,the structure of the oilfield,heterogeneity property and oil-water distribution are displayed,which have provided basis for the coming reservoir study such as precise reservoir numerical stimulation.更多还原
