| 摘 要： | 应用整合地震、各种微相定量参数与地质统计学相结合的三维地质建模方法,对大港油田西58-8稀井网区河道砂体分布进行预测。结果表明:处于同一沉积体系的紧邻的老油田密井网区的沉积微相定量表征参数可以作为稀井网区砂体预测的约束参数;地震资料预测的复合河道级别砂体分布范围可作为单河道砂体预测的最大外边界;在最大外边界及微相定量表征参数的约束下,采取示性点过程算法模拟单砂层级别沉积微相三维分布,以此为基础的"相控"模拟可以提高单河道砂体三维分布预测精度。

| Abstract: | Taking west 58-8 borefield in Dagang Oilfield as an example,the channel sandbodies distribution in sparse well network were predicted applying the methods of three-dimensional geological model that is integrated seismic data,microfacies quantitative characterization of parameters with geostatistics.The results show that the parameters of microfacies quantitative characterization towards the dense well pattern area of nearby old oilfield in the same sedimentary system can be used as the boundary parameters o... |
