基于分级控制和多信息融合的缝洞型碳酸盐岩气藏三维地质建模方法
Three-Dimensional Geological Modeling Method for Fault-Block Carbonate Reservoirs Based on Hierarchical Control and Multi-Information Fusion
摘要
Abstract
Compared with clastic reservoirs,carbonate reservoirs have extremely strong heterogeneity,multiple types of storage spaces,and uneven development of pores,caves,and fractures.How to characterize the three-dimensional storage space of strongly heterogeneous carbonate gas reservoirs is the key to fine reservoir description.By integrating geological,logging,seismic,and production dynamic data with reservoir characterization insights,this study focuses on the Maokou Formation fracture-dong carbonate reservoir in Hechuan Block.Random modeling combined with deterministic modeling methods is used to gradually construct a detailed geological model of the reservoir with various attributes such as structure,sedimentary facies,reservoir classification,porosity,permeability,and gas saturation,quantitatively characterizing the distribution characteristics of reservoir attributes.By combining geostatistics with multi-attribute collaborative simulation technology,this paper establishes a multi-scale integrated fracture-hole model,quantitatively characterizes the spatial distribution characteristics of reservoirs,and forms a set of fine fracture-hole carbonate reservoir modeling methods based on sedimentary facies-reservoir type classification control and multi-scale information fusion.关键词
