敦化盆地烃源岩特征与油气资源潜力
|
摘要
敦化盆地为一中新生代断坳叠合型裂谷盆地,油气勘探程度较低,为查明其烃源岩发育状况及油气资源潜力,在对煤田钻孔和露头样品系统化验分析与地震地质综合研究的基础上,分析了盆地发育的下白垩统、古近系、新近系3套湖相烃源岩的分布特征、有机质丰度、有机质类型和有机质成熟度,用烃产率法估算出盆地的总生烃量为31.02×108t,总资源量为1.24×108t,下白垩统和古近系湖相泥岩为盆地的成熟优质主力烃源岩,说明该区具有形成中小型油气田的物质条件。
Dunhua Basin is a Mesozoic-Cenozoic rift basin,whose exploration extent is comparatively low.In order to beat out its source rocks growth and its oil-gas potential,the paper analyzed the distribution,organic matter abundance,organic matter type and organic matter maturity of three sets of Lower Cretaceous,Paleogene and Neogene lacustrine source rocks in the basin based on the system test-analysis of the coalfield-bores and outcrop samples as well as the seismic-geological integrated research.By means of the hydrocarbon yield method,the total hydrocarbon of Dunhua Basin is estimated 31.02×108 t,and the total resource quantity of Dunhua Basin is about 1.24×108 t.It is found that the Lower Cretaceous and Paleogene lacustrine source rock is the chief-mature-organic-rich force source rock in the basin,indicating that it possesses these material conditions for forming a middle-small-scale oil-gas field.
