摘要
有机质丰度作为烃源岩评价的重要指标,在地史演化过程中不断变小,科学准确地对其进行恢复,对于油气资源评价具有重要意义。在对各种有机质丰度恢复方法进行系统分类的基础上,综合对比了各种方法的优缺点及适用条件。通过对有机质丰度恢复影响因素的分析,认为源岩的非均质性、无机CO2的产生、水热生氢等作用是影响恢复准确性的主要因素。而以热模拟实验为基础的多种方法综合应用将是有机质丰度恢复的主要发展方向。
Organic matter abundance,which declines during the period of geological time,is a very important index to evaluate hydrocarbon source rock.It is significant for petroleum resource evaluation to recover it well and truly.In this paper,various methods about recovering abundance of organic matter are collected,classified and compared with each other.Based on the systematic analysis,heterogeneity of source rock,production of inorganic CO2 and hydrothermal hydrocarbon generation play an important pole in actual recovering abundance of organic matter.The integration of various methods based on the thermal simulation experiment to recover abundance of organic matter is promising.
