【摘要】：上古生界泥岩和煤岩是阜阳探区的主力生烃层。为了明确该套生烃层的资源潜力,对烃源岩的有机质丰度、类型和成熟度进行研究,落实了优质烃源岩的分布层位和生烃类型,并估算了资源量。研究表明:上古生界烃源岩主要分布在颜集、倪丘集凹陷和古城低凸起;泥岩总体评价为好—差烃源岩,煤岩为差烃源岩;泥岩和煤岩的有机质类型都以III型干酪根为主;烃源岩有机质成熟度具有北高南低的特点,北部颜集凹陷热演化程度最高,以生成天然气为主,南部的倪丘集凹陷和古城低凸起烃源岩热演化程度适中,既可以生油又可以生成天然气。根据估算,天然气资源潜力区在颜集凹陷和倪丘集凹陷,油资源潜力区在倪丘集凹陷和古城低凸起。
[Abstract]:The Upper Paleozoic mudstone and coal rock are the main hydrocarbon generating strata in Fuyang exploration area. In order to clarify the resource potential of this set of hydrocarbon generating strata, the abundance, type and maturity of organic matter of the source rocks are studied, the distribution and hydrocarbon generation types of high quality source rocks are carried out, and the amount of resources is estimated. The results show that the upper Paleozoic source rocks are mainly distributed in Yanji, Ni Qiji depression and Gucheng low uplift, mudstone is generally evaluated as good differential source rock, coal rock is differential source rock, mudstone and coal rock are mainly III kerogen. The maturity of organic matter in source rocks has the characteristics of high in the north and low in the south. The thermal evolution degree of the Yanji depression in the north is the highest, and the generation of natural gas is the main factor, and the thermal evolution degree of the source rocks in the southern Niqiuji sag and the Gucheng low uplift hydrocarbon source rocks is moderate. It can generate both oil and natural gas. According to the estimation, the potential areas of natural gas resources are in Yanji sag and Niqiji depression, while oil resource potential areas are in Niqiuji sag and Gucheng low uplift.
