摘要
通过对东濮凹陷沙一段烃源岩有机质丰度、类型、成熟度的研究,发现东濮凹陷沙一段烃源岩主要为混合型,有机质类型较好,平均有机碳含量在0.56%-1.04%之间,属于差-较好的级别。从烃源岩的潜力指数来看,东濮凹陷沙一段生烃强度比较低,期望值为2.084×106t/km2(相当于SPI为2.1)。按照纵向排油系统和横向排油系统的潜力指数评价标准,烃源岩的充载能力分别属于低和中等。
On the basis of the research on the routine organic geochemistry such as the abundance of organic matter, type of organic matter and maturity of organic matter in Dongpu sag, it is found that the type of organic matter of the source rocks is of rather good quality in Member 1 of Shahejie Formation of Dongpu sag which are characterized by mixed-type. The average abundance of organic matter is 0.56% - 1.04%. This organic matter is considered as poor-rather good quality. The potential index of source rocks indicates that the hydrocarbon-generating density is rather low, and the expectation value is 2. 084× 10^6 t/km^2 （equal to 2.1 in SPI）. According to the standard of potential index of the longitudinal and lateral oil-expulsion system, the filling and carrying abilities of source rocks are reformed to be low and middle.
