【摘要】 柴达木盆地北缘块断带油气主要来自中侏罗统和下侏罗统的河流相、湖沼相和半深湖相的暗色泥岩、页岩和煤层。烃源岩分布面积广、厚度大,有机质丰度高、类型好;圈闭发育,圈闭形成期与油气生成、运移、聚集相匹配;储盖组合齐全;油气具有多次运移聚集、多期成藏特点。勘探领域广阔,勘探目标多,是目前中国现实的油气储量接替区之一。更多还原

【Abstract】 Oil and gas in the faulted block belt of northern margin of Qaidam Basin, are mainly come from the dark clays, shale and coal measures developed in fluvial facies, paludal facies and semi-deep lake facies of Middle and Lower Jurassic. It is characterized with wide distribution, huge thickness and high organic abundance of source rock, well-developed traps, thvorable reservoir-sealing assemblage, matchable composition of multi-stage oil/gas trapping, generation, migration and accumulation. Currently, it is one of the practical areas of oil/gas reserve suppressions in China due to its encouraging exploration prospect and multitudinous exploration targets.更多还原
