摘要
常规岩相控制建模方法体现不了不同沉积微相的储层非均质性的类型及强度,同时传统的三维沉积微相控建模虽然在一定程度上分相带反映了储层的物性变化,但反映不了同一种微相内部不同岩性所引起的储层非均质性。本文以苏里格气田苏49-01加密试验区块为例,在岩相模型的基础之上,统计各沉积微相建模所需参数,以基于目标的建模方法建立沉积微相三维地质模型。在应用沉积微相-岩石相划分方法精细表征不同成因砂体间岩性、物性差异之后,建立起研究区沉积微相-岩石相的地质知识库。继而在三维沉积微相模型内部模拟沉积微相-岩石相模型,最后以该模型约束建立起高精度属性模型,该属性模型可精细刻画不同沉积微相以及同一沉积微相内部不同岩性所引起的储层非均质性。
Normal lithofacies controlled modeling method can＇t reflect the type and strength of reservoir heterogeneity of different microfacies.Though conventional 3D microfacies controlled modeling method can show the changes of reservoir physical properties to some extent,it can＇t show the reservoir heterogeneity inside the same microfacies caused by different types of lithology.This paper takes Su 49-01 infill test area of Sulige gas field for example.On the base of lithofacies models,statistical parameters needed for microfacies modeling are obtained.And with object-based modeling method 3dsedimentary microfacies model is established.After using sedimentary microfacies-lithofacies division method to characterize the differences between lithology and physical properties of different genetic sand bodies,geological microfacies-lithofacies knowledge database is set up.And then sedimentary microfacies-lithofacies models within 3D microfacies models are established.Finally,high-resolution petrophysics models constrained by sedimentary microfacies-lithofacies models are built.Such models finely depicts the difference of reservoir heterogeneity of different microfacies and inside the same microfaces.
