中文摘要: 南鄱阳坳陷发育多套烃源岩,主要为上二叠统龙潭组暗色泥岩和煤、下二叠统茅口组泥灰岩以及栖霞组灰岩,结合煤中树皮体和镜质体的生烃模拟结果,探讨了研究区主要烃源岩的生烃能力。研究表明,区内煤中树皮体和镜质体都具很强生烃能力,且树皮体的生油能力比镜质体强得多;茅口组及龙潭组泥质烃源岩的生烃强度以坳陷西南部最大,而由北往东则呈降低之势,烃源岩厚度也以坳陷西南部较厚,表明坳陷西南部是有利的勘探区。
英文摘要: 

There are many source rocks developed at South Poyang Depression, mainly including the Upper Permian Longtan Formation of dead color mudstone and coal, the Lower Permian Maokou Formation of marl and the Lower Permian Xixia Formation of limestone. Integrated barkinite and vitrinite in coal, a hydrocarbon-generating simulation was carried out and a hydrocarbon-generating potential was explored for the main source rocks in this study area. These results illustrate that either barkinite or vitrinite are of very strong potential, in which an oil generation of barkinite is much stronger than that of vitrinite. As for Maokou and Longtan formations, a hydrocarbon-generating intensity in mud source rock shows that the maximum occurs at southwestern depression and a decrease trend appears from north to east. Additionally, the thickness of source rock at southwestern depression is the largest, reflecting the southwestern depression is a favorable exploration area.
