油页岩中含有多种来源的有机质,它们是在各种各样的环境下沉积下来的,这影响着它们的商业勘探潜力。Lowmead盆地油页岩中有机质类型的变化已参照一种综合的物理化学分类方案作了鉴别。油页岩的热解产量已经表明,用这种方案比用纯化学分类要吻合得更好。尽管热解产量(用L/t表示)足以用作油页岩商业评价的标准,但TOC(总有机炭)数据也是评价页岩油的潜在数量和质量的一种辅助指标。
Oil shales contain a variety of organic sources, which are deposited in a variety of environments, affecting their commercial exploration potential. Changes in organic matter types in oil shale in the Lowmead Basin have been identified by reference to an integrated physicochemical classification scheme. The pyrolysis yield of oil shale has shown that it is better to use this protocol than purely chemical classification. Although the pyrolysis yield (expressed in L / t) is sufficient to be used as a standard for commercial evaluation of oil shale, TOC (Total Organic Carbon) data is also a secondary indicator of the potential quantity and quality of shale oil.
