鄂尔多斯盆地庆64井区延10油层的储层三维地质建模

探讨储层建模技术在鄂尔多斯盆地元城油田庆64井区延10油层的油藏描述中的应用。通过取心井的岩心资料,综合运用岩性组合特征、沉积结构、构造特征、韵律特征、古生物特征等相标志,认为延10油层属辫状河流相沉积;分析了辫状河道、心滩、天然堤、洪泛平原4种沉积微相的岩性和电性特征,储层非均质性特征;采用序贯指示模拟技术建立了研究区沉积微相模型,并以此模型为基础进一步建立了储层参数模型。验证结果表明,在相控条件下所建模型与实际地质情况符合较好,为油藏数值模拟提供了精确的数据体,也为准确评价油气田储层性质及井网加密调整、挖掘剩余油潜力提供了依据。

According to drilling and core analysis testing and synthetically using the various facies characteristics,such as palaeontologics characteristics,deposition textures,structure features,and rhythmic features,the authors points out that the study area belongs to the braided stream facies deposition,and analyses the lithology of four kinds of sedimentary microfacies,such as braided channel,channel bar,natural levee,and flood plain,and the characteristics of cores,the electricity nature of the four microfacies...
