Abstract: Boolean method is a simple stochastic modeling techmque,which is mainly used in modeling the continuity of sandbodies and barriers in reservoirs.The method is flexible,and whatis represented by its simulated realizations is close to that predicted with sound geologicalconcepts.In this paper,the principle and the consequent algorithm for the method is described,and an application in modeling the continuty of sandbody,in a given oilfield,is givenas an example.

Key words: sandbody, reservoir model, simulation model, reservoir simulation

摘要： Boolean方法是随机建模技术的一种简单方法,上要用于早期评价阶段建立砂体连续性模型和隔层模型.本文讨论了Boolean方法的基乍原理及其相应的算法,并给出了建立A油藏A1-1～A1-4砂层组砂体连续性模型的应用实例.该方法使用灵活,模拟结果比较贴近地质概念.
