摘　　要：随着老油田进入开发后期,部分油田综合含水率达80%以上,如何通过单管冷输降低集输能耗成为重要的课题。本论文针对某油田通过粘壁温度试验确定出合理的进站油温,通过附近油田的生产实际参数确定出总传热系数,运用PIPESIM软件针对不同性质原油开展水力、热力计算,确定出了单管冷输边界条件,并针对冷输困难井开展加药降粘试验,确定出加药冷输方案,经现场应用冷输取得成功。As old oilfields enter the later stage of development,some oilfields have a comprehensive water content of over 80%.How to reduce energy consumption through single pipe cold transportation has become an important issue.This paper aims to determine a reasonable inlet oil temperature for a certain oilfield through a sticky wall temperature test.The total heat transfer coefficient is determined based on the actual production parameters of nearby oilfields.Hydraulic and thermal calculations are carried out using PIPESIM software for different properties of crude oil,and single pipe cold transportation boundary conditions are determined.Chemical addition and viscosity reduction tests are carried out for difficult cold transportation wells,and a chemical addition cold transportation plan is determined.The cold transportation project has been successfully applied on site.
