An Integrated Reservoir Modeling Programme MODRES and Its Application

针对陆相储层的特殊性及现有储层随机建模软件中存在的不足 ,以储层两步建模相结合、确定性与随机性相结合、基于目标与基于象元的策略相结合、数学分析与地质规律相结合及面向实际需要的思想作指导 ,提出了一种新的综合储层建模方法和程序 MODRES,并介绍了其主要特点。通过吐哈盆地温米油田储层建模的一个实例研究 ,具体说明 MODRES建模的特点及其应用效果。研究表明 ,在有较多数据可以得到大的储层结构特征时 ,可采用确定性方法建立结构模型 ;考虑边界的相控模拟优于一步模拟。

In consideration of the particularity of terrestrial reservoir and the shortcomings of available stochastic reservoir modeling software, a new integrated reservoir modeling method and its programme MODRES are put forward and its main characteristics are presented by combining a two-step reservoir modeling, integrating the randomness with determinacy, an object-based strategy with a pixel-based one, mathematical analysis with geologic rules as well as the thought oriented towards the practical needs. The property and application results of MODRES modeling are presented specifically through a case study of reservoir modeling in Wenmi Oilfield in Turpan-Hami Basin. It shows that when accurate reservoir structural features are obtained with more data, the structural model is established by using a deterministic method, a lithofacies controlled modeling with the consideration of boundary is better than an one-step model.
