摘要: 为了对储层沉积微相不同随机模拟方法的适应性及其优劣进行量化分析,以低渗透储层为例,采用普遍使用的截断高斯模拟和序贯指示模拟技术,进行了沉积微相定量描述的对比研究。结果表明: (1)不同模拟方法建立的微相分布模型的可靠程度不同; (2)截断高斯模拟不能真实再现相序关系复杂的微相分布,结果出现局部失真现象; (3)序贯指示模拟适用于非均质性复杂的低渗储层微相展布的描述,结果具有可信性和预测性。

Abstract: In order to discuss the adaptability, advantage and disadvantage of various stochastic simulation for sedimentary microfaces of reservoir are analyzed, and truncated gaussian simulation and sequential indicator simulation, which are generally used in quantitative description of reservoir, will be adopted to
simulate the framework of faces of a low permeable reservoir for the comparative study of different simulation technologies. The results of stochastic simulation indicate: (1) the reliability of simulating result is quite different by different simulation methods;(2)sequential indicator simulation is a much more preferable way for the simulation of complicated heterogeneous reservoirs than truncated gaussian simulation, (3)the result of the former is more reliable matching with the true cases, while the latter shows a lower accuracy.

Key words: reservoir, sedimentary micro faces, transacted gaussian simulation, sequential indicator comparison
