摘要
利用常规测井资料与有机质丰度之间的关系可以进行烃源岩评价。多测井组合法和多参数组合法可以定性识别烃源岩;密度测井法、自然伽马法、基于W—S方程的电阻率重叠法和双孔隙度法、含油气饱和度法、声波时差/电阻率交会法以及ΔlgR法等是定量评价有机质丰度,计算总有机碳含量TOC常用的方法。详细介绍了ΔlgR法的原理及应用方法,并将之应用于大庆外围盆地,与实验分析资料进行对比,验证了该方法的实用性。
Hydrocarbon source rocks can be evaluated using the relation between general log information and organic richness.Hydrocarbon source rocks can be identified qualitatively by using well—loggings combination method and parameters combination method.There are many Methods to evaluate organic richness quantificationally and calculate total organic carbon content(TOC).Methods in regular use are Densilog method,Gamma ray log method,Overlay and dual porosity method based on Waxman-Smith equation,Hydrocarbon saturation method,Sonic interval transit time-resistivity cross method and method ofΔ1gR.There is a particular introducation to method ofΔ1gR.We applied method ofΔ1gR to basins in Songliao basin periphery and contrasted the result with information of experimental analysis.The result validated its practicability.
