摘　　要：我国东部陆相断陷盆地经过多年的勘探实践,已经逐步形成了以"陆相生油"、"源控论"为代表的陆相石油地质理论。从最初的背斜油气藏勘探到现今的隐蔽油气藏勘探,中国陆相断陷盆地油气形成和分布规律经历了以下历程:在大庆油田发现的基础上总结出来"源控论"(20世纪60～70年代);在以渤海湾盆地为代表的陆相断陷盆地勘探成果的基础上提出的"复式油气聚集带理论"(20世纪80年代);胜利油田地质工作者在东营凹陷的勘探过程中总结的"环洼聚油"理论(20世纪90年代);在对二连盆地的隐蔽油气藏形成及分布特征研究时提出的"互补性"特征(2003年)、"优势论"特征(2005年)以及"多元控油—主元成藏"新观点(2006年)。这一系列认识和新观点不仅在指导我国陆相断陷盆地的油气勘探中起到了重要作用,也大大丰富了我国以陆相生油为主线的石油地质理论。In recent years,with the development of oil and gas exploration in continental fault basins in eastern China, continental oil geology theory has gradually formed with the representation of ＂Continental Oil Generation＂ and ＂Source Control Theory＂. From the former anticlinal reservoir exploration to nowadays subtle reservoir exploration, the hydrocarbon formation and distribution rules of continental fault basin can be divided into four historical stages： 1960＇ s-1970＇ s, ＂Source Control Theory ＂, proposed on the basis of the discovery of Daqing Oilfield; in 1980＇s,＂composite zones of hydrocarbon accumulation theory＂ based on the exploration achievements in continental fault basins, especially Bohai Bay Basin; in 1990＇s,＂ oil accumulation around the sag＇concluded by the geologists during the exploration in Shenli Oilfield; till now, new viewpoints of ＂complementarity characteristics＂ （2003）, ＂predominance characteristics＂ （2005）, ＂multi-factor controlling and key-factor entrapping＂ （2006） presented during the study on the subtle reservoir exploration in Erlian Basin. All these viewpoints not only take a significant part in the exploration in continental fault basins, but also improve the oil geology theory with the representation of ＂Continental Oil Generation＂.
