储层随机模拟技术能有效地描述储层非均质性,定量化研究储层评价中的不确定性,已在储层建模领域应用越来越广泛。然而建立储层沉积相模型是储层随机建模的重中之重。本文通过实例,建立三维相模型,储层物性模型,并对储层开展了随机建模研究。所建立的三维储层地质模型,为准确评价油气田储层性质,井网调整,以及剩余油挖潜提供了可靠依据。
Reservoir stochastic simulation technology can effectively describe the reservoir heterogeneity and quantify the uncertainty of reservoir evaluation. It has been widely used in reservoir modeling. However, the establishment of reservoir sedimentary facies model is the most important factor in reservoir stochastic modeling. In this paper, a three-dimensional phase model and reservoir physical model are established through examples, and stochastic modeling is carried out on the reservoir. The established three-dimensional reservoir geological model provides a reliable basis for accurately evaluating the nature of oil and gas reservoirs, well pattern adjustment and potential oil tapping.
