摘要
ΔlogR方法是一种利用测井资料识别和计算含有机质岩层总有机质碳的方法.本文通过对ΔlogR方法的应用,总结出该方法的优点可以消除对孔隙度的依赖关系,其缺点是Toc的背景值,这个值存在有很大误差.烃源岩的ΔlogR方法的定性解释对高含有机质的地层和成熟的源岩层比较有效.
ΔlogR method is used to identify and compute the organic carbon with logging surveys. In this paper, author include the advantage and shortage of ΔlogR method applied on the identification of source rock , which is ease to eliminate the relation on porosity. And on the hand it is difficult to make certain the parameter value of T_(oc) . The interpretation method of using ΔlogR is much effective on the stratum contain. more organic matter and full-blown source rock.
