储层三维建模及在油藏描述中的应用研究

储层三维建模是精细油藏描述的核心，随着我国大部分油田的开发进入中后期阶段，油藏的研究要求更高的定量化，储层的描述要求更加精细，建立精度较高的储层三维模型非常有意义.文中介绍了构造模型、相模型和属性参数模型常用的建模方法原理，分析其优缺点，并对多点统计的新方法进行了描述.讨论了模型在油藏研究中的应用状况，并以彩南油田彩9区为实例，从三种模型提供的储层信息，寻找有利潜力区的位置，并对目前注水开发中存在的问题给予了合理的解释，从而为下一步油田的开发提供一些参考.

3D reservoir modeling and its application

3D reservoir modeling is the key of reservoir characterization.With the coming of middle-later developing stage of most oilfield,the study of reservoir needs more accurate quantitativeness,and reservoir characterization requires more precise,so the high precision 3D model is very significative.The modeling theory and methods of structure model,facies model and property model are introduced in the paper,then their advantages and disadvantages are analyzed,and the new method,multiple point statistics,is mentioned here.We talk about the application in the reservoir study.As an example of Cai9 Block model,using the information of the models can help us find the potential location,reasonably interpret the problem existing in the oilfield developing,and provide some helpful reference for next exploitation.
