摘要： 三塘湖盆地二叠系芦草沟组二段发育一套沉凝灰岩烃源岩层系，地层厚度大，有机质丰度高，类型好，整体处于生油窗内，油气以“自生自储”就近聚集成藏为主，烃源岩即是好的产油层，为典型的源岩油成藏特征。源岩油勘探主要评价储集层可动烃含量，本文探讨了利用录井气测、定量荧光、岩石热解以及核磁共振测井技术定性和定量表征源岩油中的可动烃，根据实测数据，用岩石热解法对其可动烃资源量进行定量估算，三塘湖盆地马朗凹陷二叠系芦草沟组二段源岩油可动烃资源约5.53×108 t，资源丰度可达300×104 t/km2，源岩油勘探潜力较大。

Abstract: A set of tuffite hydrocarbon source rocks developed in the second member of Permian Lucaogou formation, Santanghu basin, is characterized by large thickness, high abundance of organic matters, good organic matter type, and being in the oil generation window. Self-generation and self-storage is the main hydrocarbon accumulation pattern, source rocks are the good pay zones which have the typical characteristics of hydrocarbon accumulation in source rocks. Evaluation of movable hydrocarbon content in reservoirs should be focused on during source-rock oil exploration. The paper discusses the qualitative and quantitative characterization of movable hydrocarbons in the source-rock oil by using mud log, quantitative fluorescence, rock pyrolysis and NMR technologies. The movable hydrocarbon resources are estimated quantitatively with rock pyrolysis method. The result shows that the movable hydrocarbon resource in the source-rock oil of Permian Lucaogou formation in Malang sag, Santanghu basin is 5.53×108 t, resource abundance reaches 300×104 t/km2, which demonstrates that there is great potential for source-rock oil exploration.
