The study of hydrocarbon reservoir heterogeneity is one of the main fileds of reservoir characterization and thus has been highlighted in research for decades.The study of reservoir heterogeneity mainly includes classification,evaluation and mechanism of the heterogeneity and its influence on reservoir production.The study of reservoir heterogeneity in international community mainly includes:physical property analysis based on experiments and its influence on fluid percolation;and quantitative analysis of reservoir heterogeneity by using methods of reservoir modeling and simulation based on outcrop data.In contrast,the study in China mainly comprises:analysis of the geological origin of the heterogeneity using methods of sedimentology and diagenesis;and quantified evaluation of the heterogeneity by using parameters of physical property (e.g.,permeability) based on fine interpretation of logging data.Research methods of the reservoir heterogeneity mainly include geological origin,sequence stratigraphy,experimental,geological statistical,mathematical calculation,logging interpretation,geological modeling,seismic prediction and analysis of production performance.Combined with personal research experience,we address the advantages and disadvantages of these methods and further propose the main problems and future directions of the study of reservoir heterogeneity.%储层非均质性作为储层表征的核心内容之一,一直是研究者关注的焦点.储层非均质性的研究内容主要包括储层非均质性分类、储层非均质性评价、储层非均质性成因分析和储层非均质性对油气田开发的影响等.国外对于储层非均质性研究主要包括利用各种实验研究储层孔渗等物性特征及其对流体渗流规律的影响、利用野外露头资料开展地质建模和模拟研究进行储层非均质性定量分析.国内主要包括通过沉积学、成岩作用等地质成因分析研究储层非均质性和基于测井精细解释的渗透率等储层物性参数进行非均质性的定量评价等.研究方法有地质成因分析法、层序地层学方法、各种实验研究方法、地质统计学方法、各种数学计算方法、测井解释方法、地质建模方法、地震预测方法、数值模拟方法和生产动态分析法等.结合自身科研实践,分析了不同研究方法的优缺点.在此基础上指出了目前储层非均质性研究中存在的主要问题和今后的发展方向.
