由于储层的非均质性及油藏类型的复杂性，加之注采井网的不完善性，导致地下油水运动十分复杂。在这种情况下,很难精确预测井间储层参数分布和剩余油富集区域。针对上述难点和挑战，通过利用储层建模技术，建立了储层地质模型及其预测模型，从而在很大程度上加强了精细油藏描述中基础数据的管理。利用随机建模的储层建模技术是当今油藏表征技术的一个重要组成部分，该技术能有效刻画储层非均质性，定量研究储层评价中的不确定性，从而有力地推动着油藏描述技术向定量化方向发展。

The needs of modern reservoir management and enhancing the recovery ratio make people have to build the reservoir model with higher and higher accuracy and precision. The reservoir modeling technology has greatly enhanced the degree of reservoir description computerization, which strengthens the basic data management of fine reservoir description to a large extent. The stochastic modeling technology of oil and gas reservoirs is an important part of reservoir characterization. It can effectively show the reservoir heterogeneity and quantitatively study the uncertainty factors during reservoir evaluation, which effectively promotes the
development of reservoir description technology towards quantification direction. This paper emphatically discusses the conceptions, steps and methods of reservoir stochastic modeling.
