摘　　要：在录井解释评价过程中经常用到全烃和组分,由于全烃和组分测录方式不同,两者是何种关系一直存在争论,一种观点认为全烃近似等于组分之和,另一种观点认为应根据烃类等碳效应计算全烃值。考虑到全烃值与组分的关系不是简单的体积分数和,在解释评价中,全烃值采用根据组分的燃烧热建立的函数值相对更加准确,为得到更准确的全烃值,从气相色谱工作原理入手,结合烃组分燃烧热进行探讨,建立气测全烃与组分的函数关系,提供了一种新的全烃值测算理论依据,其应用效果有待进一步发掘。In the process of mud logging interpretation and evaluation, total hydrocarbon and components are often used. Due to the different logging methods of total hydrocarbon and components, there has been controversy about the relationship between them. One view is that total hydrocarbon is approximately equal to the sum of components, and the other view is that the total hydrocarbon value is calculated according to the iso-carbon effects of hydrocarbon. Considering that the relationship between the total hydrocarbon value and the components is not a simple volume fraction sum in interpretation and evaluation, the total hydrocarbon value is relatively more accurate using the function value based on the combustion heat of the components. In order to get a more accurate total hydrocarbon value, starting from the working principle of gas chromatography and combining with the combustion heat of hydrocarbon components, the functional relationship between total hydrocarbon and components in gas logging is established, which provides a new theoretical basis for the calculation of total hydrocarbon value. Its application effect needs to be further explored.
