通过对ΔlogR技术、多元回归预测模型、颜色预测模型的原理、方法、特点展开分析，对这三种方法的适用性和约束条件进行总结，认为ΔlogR技术需对目的层分段处理并要求泥质岩处于低成熟—成熟阶段（0.6％＜Ro ＜1.2％）；多元回归预测模型具有区域局限性；颜色预测模型要求样品为暗色非均质泥质岩。TOC测井评价的方法能够提供纵向上TOC分布曲线，克服取心不足的困难，解决分析测试的经济问题。结合鄂尔多斯盆地中东部地区二叠系山西组泥质岩的地质特征进行TOC预测，结果显示运用五元回归的方法预测效果最好，相关系数为0.8978。%Through analyzing the theories,methods and characteristics for the ΔlogR technique,the multiple regression and color prediction models,the applicability and constraint condition were summarized.The study results indicated that the ΔlogR technique requires segment treatment for target layer and mudstone shale at low mature-mature stage (0.6 %展开▼
