摘要
对法国石油研究院利用测井资料计算烃源岩有机碳含量的CARBOLOG法的原理进行了剖析,推导出利用声波测井及电阻率测井资料计算总有机碳含量的理论关系式,弥补了CARBOLOG法利用电测资料作图评价有机质丰度的不足,较大程度地改进了方法的可操作性。以取芯较好的牛38井分析测试资料为基础,进行回归计算,标定了理论关系式的相应系数,相关系数为0.90,该成果在东科1、丰112、富15等井的生油岩评价中得了到进一步的检验。
The theory of CARBOLOG (developed at the Institute France du Petrole) is studied considerably and a theoretical formula is deduced. Based on sonic and resistivity data, the formula can be used to assess the total organic carbon (TOC) more practically and simply without complex plotting. The coefficients of the formula are regressed according to the well-logging data of Well Niu-38 and the correlation coefficient is 0.90. The method has been tested on Well Dongke-1, Well Feng-112 and Well Fu-15.
