Microfacies Modeling in Fine Reservoir Description
【摘要】 从区域沉积学分析和运用高分辨率层序地层学建立地层分层数据库两方面入手,分析了精细油藏描述中沉积微相建模研究的基础。结合建模实践,详细介绍了当前沉积微相建模中广泛使用的利用地质、地球物理、油田开发动态数据等信息基于目标和基于象元的各种随机建模方法和构型分析法、井间地震等建模新技术,并对各种方法和技术的优缺点进行了简评。在此基础上分析了沉积微相研究中应注意的建模方法技术、建模软件的选择、相模型的验证和优选等问题。针对目前的研究现状和存在的问题,指出了精细油藏描述中沉积微相建模研究的发展趋势。
【Abstract】 This paper first analyzes the foundation of microfacies modeling in fine reservoir description based on the region sedimentary analysis and the establishment of stratum data base by high resolution sequence stratigraphy.It also introduces the modeling methods and techniques that are widely used in present microfacies modeling,such as object-based and pixel-based technology of architecture analysis and crosswell seismic technology and other techniques of geology and physical geology and development dynamics information with some evaluation of their advantages and disadvantage.With a summary of these methods,it suggests that care should be taken in the choice,the test and the optimization of these models in the process of microfacies research.Meanwhile,it points out the tendency of microfacies modeling in fine reservoir description.
【Key words】 sedimentary analysis; high resolution sequence stratigraphy; microfacies modeling; architecture analysis; crosswell seismic technology; modeling method and technique;
