摘要
由于受有机质分布的非均质性和取样人为性等因素的影响，常规的岩心取样分析烃源岩有机碳含量的方法常有一定的偏差。利用测井资料信息连续性的特点，通过建立声波时差和电阻率曲线与有机碳含量间的定量关系模型，求取烃源岩有机碳含量在剖面上的连续分布值，从而为正确评价烃源岩提供了一种新的方法。
A usual method for assessing the organic carbon content of source rocks is through a laboratory analyses There is a deviation in calculating organic contents because of non uniform distribution of organic matter. A new method for identifying and calculating TOC in organic rich rocks is studied using common well logging information, in which the relationship between sonic transit time and resistitvity log and organic carbon content is established.According to the method, sonic transit time and resistivity curves can be used to determine accurately organic richness and provide a continuous TOC value. A practical example proves the new method efficient
