【摘要】 针对吴起采油厂L6区块日趋严峻的开采矛盾、储层非均质性严重的特点,采用相控随机建模技术建立本区的精细储层地质模型。通过小层的精细划分建立构造模型,根据井网密的特点,应用岩石相与沉积相结合的方法,采用序贯指示模拟法建立沉积相模型,在沉积相的控制下,采用顺序高斯模拟法建立储层物性模型,成功实现了L6区块精细油藏描述,为提高油藏数值模型的精度打下了良好基础,为剩余油挖潜工作提供依据。更多还原

【Abstract】 According to the increasingly severe exploitation conflicts and the reservoir heterogeneity characteristics in L6 Block of Wuqi Oil Production Plant, the paper adopts phased stochastic modeling technology to establish the geological model of fine reservoir in this area. The structure model is established by the fine dividing of small layer, and according to the characteristics of dense well pattern, the combination of rock facies and sedimentary facies method is applied. The sedimentary facies model is established by the sequential indicator simulation method. Under the control of sedimentary facies, the reservoir physical model is established by using sequential Gaussian simulation, which successfully achieved the fine description of reservoir in L6 Block. The study lays a good foundation to improve the accuracy of reservoir numerical model, and provide scientific references to the exploitation of remaining oil.更多还原
