摘　　要：廊固-大厂凹陷为基底上发育的古近纪箕状断陷湖盆,受构造运动的控制,断裂体系发育,湖盆演化控制着沉积地层的展布,新生界古近纪沙河街组为主要含油气层段。受构造、岩性、地层等因素的共同控制,该区发育有丰富多样的油气藏类型,包括构造油气藏、地层油气藏、岩性油气藏、潜山油气藏及复合型油气藏共计五大类十二亚类。构造油气藏是研究区主要的油气藏类型,发育有断块油气藏、断鼻油气藏及背斜油气藏。As a half-graben down-faulted lake basin formed in the post plaeogene,controlled by the tectonic movement,the fracture system of Langgu-Dachang sag is complicated. The development of the lake basin played a decisive role in the deposit stratum.Shahejie Formation is the major oil con- tainer layer.Because of the structure,the lithology,the stratum and other factors,various types of oil-gas reser- voirs were formed in the study area.They are structural res- ervoirs,stratigraphic reservoirs,lithological reservoirs, palaeo-buried hill reservoirs and combination reservoirs. The structural reservoirs including the fault block reservoirs, the fault-nose reservoirs and the anticline reservoirs are the main oil-gas reservoirs of the study area.
