基于动态资料约束的储层迭代建模研究

摘要

基于油藏地质建模和数值模拟技术,研究利用动态资料约束储层建模的新方法,并在埕岛油田馆上段南区进行实际应用.结果表明:提出的储层模型可靠性表征方法,以量化的形式可以准确地描述储层模型的整体和局部可靠性；通过动静态拟合矛盾的影响因素分析,采用排除法和迭代法,能够快速地找出造成储层模型不可靠的地质因素,从而约束、修正储层模型,实现了地质建模与数值模拟技术的相互渗透和有效融合,可以大幅度提高储层模型的可靠性.%Based on reservoir geological modeling and numerical simulation technology, a reservoir modeling method constrained by dynamic data was researched and applied to the south area of the upper member of Guantao formation, Chengdao Oilfield. The results show that the presented reliability characterizing method of reservoir model can accurately describes the reliability of overall and local model in a quantitative form. The cause of reservoir model unreliability can be confirmed quickly by using exclusive method and analyzing matching contradiction between static and dynamic data. The reservoir model can be constrained and modified by using iterative method. The mutual infiltration and effective integration between geological modeling and numerical simulation technology are realized. The reliability of the reservoir model can be greatly improved.
