摘　　要：　沉积模型是地层分析的重要工具,可以分为比例尺模型、概念模型和数学模型三大类型.其中数学模型又可分为确定性模型和随机模型.在实际地层分析及模拟工作中,特别是在小尺度问题的研究中,采用随机模型(或称统计学模型)往往更为有利.储层随机建模技术,作为这方面研究的典范,近年来成为储层预测和风险评价的一项较为有效的手段.然而,由于研究目标的复杂性,不同沉积模型之间的嵌套制约关系亦应引起重视.Sedimentation models are important tools to research strata and include scale models, conceptual models and mathematical models. Statistical models, as one kind of mathematical models, are very important for there are many statistical features in strata. Stochastic reservoir modeling, as one method of statistical modeling, embraces success for its appearance in reservoir research and begins to be employed in other domains. However, for the sophistication of research targets, the relationship between them or among them should be taken into account.
