【摘要】 赵彦超等．碳氧比测井──一种潜在的生油岩评价工具．测井技术，１９９４，１８（４）：２４０～２４７生油岩测井评价是测井地层评价的新领域。从生油岩的岩石体积模型入手，建立了生油岩的碳氧比测井响应方程，并用实际资料分析了生油岩在碳线比测井曲线上的特征，然后以ＳｕｓａｎＬ．Ｈｅｒｒｏｎ公式为基础，利用Ｃ／Ｏ，Ｓｉ／Ｃａ资料重新推导了计算生油岩有机碳的公式，并以某油田的两口井资料进行了试算。结果表明：碳氧比测井是一种潜在的生油岩评价工具。更多还原

【Abstract】 Logging evaluation of source rock is a new branch in formation evaluation. C/Ologging response equation has been established according to the volume model ofthe source rocki and by using the measured data, we have analysed the C/O response characteristics to source rock. Based on Susan L. Herron’ S equation, rederived in this paper is the equation to calculate the total organic carbon (TOC) ofsource rock with C/O and Si/Ca data land the data computed from two wells haveproved that C/O log is a good tool to evaluate source rock.更多还原
