摘　　要：呵叻盆地H区是延长油田重要的海外油气勘探区块。为明确该区二叠系油气成藏成藏模式,分析了烃源岩及油气输导体系,对典型油气藏进行了解剖。研究表明:呵叻盆地内以二叠系烃源岩为主,潜在的烃源岩为石炭系和三叠系Huai Hin Lat群;主要有地层不整合型、地层-构造-不整合型、构造不整合型、构造型以及透镜体型等五种类型圈闭;油气成藏模式为"断裂通源,裂缝输导,储层控富,不整合遮挡,自生自储"。The H area of Korat Basin is an important overseas oil and gas exploration block in yanchang oilfield.In order to clarify Permian hydrocarbon accumulation model,the source rocks,oil and gas transport system were analyzed,and the typical oil and gas reservoirs were dissected.It shows that Permian source rocks are dominant in the Korat Basin,and the potential source rocks are carboniferous and Triassic Huai Hin Lat group.There are five trap types which are stratigraphic unconformity,stratigraphic structure-unconformity,tectonic unconformity,tectonic unconformity,and lenticular type.Oil and gas accumulation model is " fault source,fracture transmission,reservoir enrichment control,unconformity shielding,self-generation and self-storage".
