保持油藏非均质性粗化方法

油田三维地质模型网格数据量庞大,无法直接用于数值模拟,需粗化处理,减少网格数量。以具体区块为例,用重整化方法对储层参数,特别是渗透率进行粗化,对夹层及非均质性较强部位运用网格回填技术,所建粗化模型经多方面评价,达到既降低网格数量又保持油藏非均质性的技术要求。

Scaling Method of Containing Reservoir Heterogeneity

the data of three -dimensional geological models was very large,this kind of three -dimensional geological model could not be directly used for numerical simulation and must be scaled for small data. The reservoir parameters ,especially permeability,were scaled by renormalization technique , sandwiches and partes of strong heterogeneity were filled back in one real study zone.The modle was evaluated by many methods, not only it reduces number of grides,but also contains the reservoir heterogeneity.
