摘　　要：本文主要对含蜡原油化学进行计算研究。一方面,根据燃料化学反应的常用计算方法,得出了油田含蜡原油的比化学反应,并通过对比前人得出的燃料油的比化学反应值,证明此方法切实可用;另一方面,从化学扩散的一般计算表达式出发,基于管输过程蜡分子的扩散沉积机理,推导得出原油扩散的计算式,并对管输过程中油流扩散的变化情况进行了分析,旨在为以后进一步研究原油输送系统的分析提供理论基础。In this paper,the chemical exergy in waxy crude oil pipeline transportation process was mainly calculated and studied.On the one hand,the specific chemical reaction exergy of waxy crude oil in oilfield was derived according to the common calculation method for fuel chemical reaction exergy,and the calculation results in this paper was proved to be practically available through comparing the results with fuel oil chemical reaction exergy which was calculated by predecessors.On the other hand,the equation of waxy crude oil diffusion exergy was derived according to the common calculation method of chemical diffusion exergy and the mechanism of waxy crude oil diffusion and deposition,the change situation of oil flow diffusion exergy in pipeline transportation process was then studied.The research on this issue aimed at providing a theoretical basis for further study on the analysis of crude oil transportation system exergy.
