输油管道的工作环境复杂,影响输油生产的因素也多,如沿程土壤组分、含水率、地下水位变化、气温和地温的规律变化及含蜡原油在输送过程中蜡晶的析出等等。为此,在输油管道工艺计算中常选设一些工艺参数,然后加以修正,原油比热C就是其中参数之一。本文介绍了大庆原油比热的计算方法,论述了比热对输油管道传热系数及正平衡法计算炉效的影响,指出原油比热是一个不可忽视的工艺参数。
The working environment of oil pipeline is complex, and there are many factors that affect oil production. For example, the variation of soil components, water cut, groundwater level, temperature and ground temperature and the precipitation of waxy wax during the transportation of waxy crude oil etc. . To this end, in the calculation of oil pipeline technology often set some process parameters, and then be amended, the specific heat of crude oil C is one of the parameters. This paper introduces the calculation method of specific heat of crude oil in Daqing, discusses the effect of specific heat on the heat transfer coefficient of pipeline and the method of positive balance, and points out that the specific heat of crude oil is a process parameter that can not be ignored.
