Abstract
Analyzing the current status and cutting-edge trends of reservoir heterogeneity is of great signifi-cance for promoting the development of the discipline.Based on China National Knowledge Infrastructure(CNKI)as the data source and utilizing literature visualization analysis software,an in-depth analysis was conducted on the core research teams,high-frequency hotspots,and cutting-edge trends in this field.The existing methods for studying reservoir heterogeneity were summarized as geo-statistical,geological a-nalysis,logging interpretation,and experimental analysis methods,and the characteristics of each method were compared and analyzed.Finally,the main problems and improvement ideas faced by the domestic res-ervoir heterogeneity field were identified.The results show that the trend of publishing papers in the field of reservoir heterogeneity is increasing in stages,and the quantitative characterization method of reservoir het-erogeneity is the key hotspot.Scholars YANG Shaochun,YU Jingwei,and LIN Chengyan and their teams have gathered the main research forces in this field,and the heterogeneity research of unconventional oil and gas resource reservoirs such as shale reservoirs and tight sandstone reservoirs has developed rapidly.The four main research methods of geological statistics,geological analysis,logging interpretation and test analy-sis have their own characteristics.The comprehensive and accurate evaluation of reservoir heterogeneity can be realized by comprehensive use of various technical means.关键词
