摘要
为了对平庄-马厂盆地油气资源做出客观评价,对盆地发育的九佛堂组、沙海组两套烃源岩有机质丰度、有机质类型和有机质成熟度进行了综合分析。结果表明:沙海组烃源岩有机质丰度较高,为中等—好烃源岩,有机质类型以ⅡB型为主,有机质处于未成熟—低成熟阶段,其生烃能力对盆地贡献小;九佛堂组烃源岩的有机质丰度高,属好的烃源岩,有机质类型为ⅡB—ⅡA型,处于低成熟—成熟阶段,具有较好的生烃能力。
Systematical analysis is made concerning the organic matter abundance, types and maturity of the hydrocarbon source rock in Jiufotang Formation and Shahai Formation for an objective evaluation to the oil and gas resources of Pingzhuang - Machang Basin. It is found that in the hydrocarbon source rock of Shahai Formation, the organic matter is abundant, almost belonging to Type ⅡB- The organic matter is developing at the prematurity stage, with little contribution to the basin generating. In the hydrocarbon source rock of Jiufotang Formation, the organic matter abundance is higher, ranging from Types Ⅱ B toⅡ A, developing at an early maturity stage with a better hydrocarbon generating capacity.
