摘 要：以三塘湖盆地马朗凹陷二叠系芦草沟组页岩油为例，以原油富集层段的生烃潜力评价和储集性能评价为基础，用“连续型”油气富集资源评价的思路，对马朗凹陷进行“全石油系统”资源评价单元划分。根据含油率、含油饱和度、孔隙度三者的关系，结合现今开采工艺，确定页岩油富集的含油率下限，并通过选取每个单元内具有代表性的钻井数据，采用体积法预测全区页岩油资源潜力。预测结果表明：本区至少有1.76×10⁸ t原油储量规模，资源潜力巨大。

Abstract:Based on the hydrocarbon generating potential evaluation and the reservoir performance evaluation of the shale oil enrichment layers, the shale oil potential of Permian Lucaogou Formation in the Malang Sag was predicted. By the resource assessment method of successive hydrocarbon type, the target formation of the Malang Sag can be divided into different prediction units. According to the present level of production technology and the relationship of evaluation parameters, such as oil content, oil saturation and porosity, the limit of oil content for shale oil enrichment is defined. By the prediction of each prediction unit with the well data, there is at least 1.76×10⁸ t crude oil in this area.
