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。
This paper mainly studies the chemical composition of waxy crude oil. On the one hand, according to the common calculation method of chemical reaction of fuel, the specific chemical reaction of waxy crude oil field is obtained, and the ratio of chemical reaction of fuel oil obtained by predecessor is proved to be practicable. On the one hand, starting from the general calculation expression of chemical diffusion, based on the diffusion and deposition mechanism of wax molecules in pipeline transportation process, the calculation formula of crude oil diffusion is deduced and the variation of oil flow diffusion during pipeline transportation is analyzed , Which aims to provide a theoretical basis for further analysis of crude oil transportation system in the future.
