摘要: 松辽盆地深层发育众多晚侏罗世—早白垩世断陷盆地,这些断陷盆地富烃程度差异很大。通过对50多个断陷的研究发现,造成富烃差异的原因在于断陷形成的地质条件不同,这些地质条件包括:断陷在盆地中所处的位置;断陷结构的差异性;控断断裂的活动强度和期次;火山作用。其中最关键的是断陷在盆地中所处的位置以及结构的差异性。这些规律对松辽盆地深层外围断陷的战略选区和评价具有重要参考价值。

Abstract: Many late Jurassic to early Cretaceous rifted basins developed in deep Songliao Basin. The hydrocarbon enrichment degree of the basins varies a lot from each other. According to the research of more than 50 rifted basins, it is found that the different geological conditions result in the difference. The geological conditions include: the location of fault depressions in the basin, the difference in the structure of fault depressions, the activity intensity and periods of the controlling fractures, and the volcanism. Among them, the location of fault depressions in the basin and the difference in the structure are the most important. These rules can be important reference to the evaluation of the strategic area selection of peripheral fault depressions in deep Songliao Basin.

Key words: Songliao Basin, fault depression, fault structure, volcanic rocks, hydrocarbon-rich fault depression
