摘要 油砂作为常规油气资源的重要补充,在国际能源供给结构中占有重要地位.研究表明,油砂成矿作用具有生成、运移、储集、破坏、保存“五位一体”的特点,贯穿其“源-运-储-破-保”的全成矿过程,其中储集、破坏、保存作用对于油砂成矿尤为关键.分析认为,发育原始油藏是油砂形成的物质基础,储集和保存作用是油砂规模和含油性高低的关键控制因素,同一盆地常规油气及油砂、页岩油气等非常规油气“同根同源”,要以油气系统观念开展综合勘查工作,注重在断裂“纵横交错”区域、不整合面附近,及原始油藏储集砂体发育区寻找油砂矿体,油砂成矿作用过程研究对探寻油砂矿深边部常规、非常规能源“就矿找矿”具有重要启示和借鉴意义. Oil sands,as an important supplement to petroleum,occupy a high position in the international energy supply.Researches show that the mineralization is characterized by the“Five in One”process of generation,migration,storage,destruction and preservation,which throughout the entire mineralization process,and the storage,destruction and preservation are more important for the oil sands mineralization.Analysis suggests that the development of primitive oil reservoirs is the material basis for the formation of oil sands,and the role of storage and preservation is the key control factor for the scale and oil content of oil sands.Conventional oil and gas in the same basin and unconventional oil and gas such as oil sands and shale oil and gas have the same origin.Therefore,comprehensive oil and gas exploration should be carried out based on the concept of oil and gas systems,with a focus on searching for oil sand deposits in areas where faults crisscross,unconformities,and sand bodies in primitive oil reservoirs are developed.The study of the process of oil sand mineralization has important implications and reference significance for exploring the conventional and unconventional oil and gas in the deep and edge of oil sand deposits.
