摘要: 随着油田开发进入后期, 一些已建管道输量低于管道的最小起输量, 末站进站温度低于油品的凝点,无法满足管输的要求, 可通过选取合适的降凝剂, 降低油品的凝点, 满足油品管输需求。采用原油加降凝剂输送的方法, 可在不新建加热站的情况下节约输送成本。为了筛选降凝剂并确定降凝剂的注入量, 进行了实验研究。研究
结果表明, 选择质量分数为5 0μ g / g的CN 1 - 6H 9 1降凝剂时, 混合原油的凝点从1 5. 0℃下降至4. 0℃, 低于进站温度, 可满足管输要求。

Abstract: When the oilfield development entered the later stage, the throughput of some existed pipelines was lower than the minimum throughput pipeline. The terminalstation the temperature of the oil was lower than the oil condensation point, which could not meet the requirements of pipeline transportation. The appropriate PPD could be chose to reduce oil condensation point, which need not build new heatingstation and effectively cut the transportation costs. Usually experimental method was adopted to select the PPD and determine the injection quantity. The results show that adding the CN16H91 pour point depressant that its mass fraction was 50 μg/g could make the solidifying point of the mixed oil fall from 15.0 ℃ fell to 4.0 ℃, it was lower than the inlet temperature to meet the requirements for pipeline transportation.

Key words: Crude oil, Temperature drop, PPD, Condensation point, Viscosity
