过去,从井口到外输的整个油气生产(集输)过程的各个环节,通常是分段考虑的。各段只根据所属环节的需要进行加热,从而浪费了大量的热能。今后,应把采油、集油、脱水、稳定、热处理、外输六个环节或其中几个环节结合起来统一考虑,以减少加热次数,改善原油的低温流动特性,降低输油温度,从而节约能源。 In the past, the whole process of oil and gas production (gathering and transportation) from the wellhead to the external transport was usually considered in stages. Each segment is heated only according to the needs of its own sector, thus wasting a lot of heat. In the future, oil production, oil gathering, dehydration, stabilization, heat treatment and external transportation should be combined into one or more of them to reduce the heating frequency, improve the low-temperature flow characteristics of crude oil, lower the oil temperature and save energy .
