摘　　要：中国部分油田采出液含水率高达90%以上,造成地面集输系统的大量热能损耗。在国家“双碳”目标下,低温集输工艺将成为油田节能降耗的主要手段。本文总结了原油低温集输管道水力热力计算研究现状,重点阐述了原油组成、水相组成及流动条件对低温黏壁现象的影响。对现阶段应用较为广泛的低温集输黏壁预测模型作了总结和分析,梳理了低温集输边界条件的研究方法与实验装置。通过开展单井和集输干线现场低温输送试验充分验证了低温集输的可行性,为现场开展低温集输工作积累了宝贵的工程案例经验。最后,就低温集输黏壁现象未来的研究方向提出了展望,认为应加强理论预测模型的建立。In some oil fields in China,the water content of produced liquid is more than 90%,which causes a large amount of heat loss in surface gathering and transportation system.Under the national“dual-carbon target”,low-temperature gathering and transportation technology will become the main means of energy saving and consumption reduction in oil fields.This paper summarizes the research status of hydraulic and thermal calculation of crude oil low-temperature gathering pipeline,and focuses on the influence of crude oil composition,water phase composition and flow conditions on low-temperature wall sticking phenomenon.The low-temperature gathering and transportation wall sticking prediction models widely used at the present stage are analyzed,and the research methods and experimental devices of the boundary conditions of low-temperature gathering and transportation are combed.The feasibility of low-temperature gathering and transportation is fully verified by the field low-temperature transportation test of single well and gathering trunk line,which accumulates valuable engineering case experience for the field low-temperature gathering and transportation work.Finally,the future research direction of wall sticking phenomenon in low-temperature gathering and transportation is prospected,and it is considered that the establishment of theoretical prediction model should be strengthened.
