摘　　要：某国外油田新建地面工程设施,包括井场、中心处理站、油田内部管线,该油田原油析蜡点63℃,倾点45℃,粘度不高,属于典型高凝高含蜡原油,给管线输送带来一定困难。根据其特点,通过软件模拟计算,从技术、经济角度对管输工艺和设计温度的选择进行了研究,同时结合国内高凝高含蜡原油管输的生产经验,确定了本项目高凝高含蜡原油管输温度设计原则按照倾点以上5℃考虑。A new--built foreign oilfield surface engineering facilities, including the wellpads, flow- lines, central processing facilities, The characteristics of the crude oil is high pour point ＆ high wax con- tent crude oil with low viscosity, PP 45℃, WAT 63 ℃ ,which bring difficulties for the transportation. The research for the transportation technology and design temperature was carried on from technical and e- conomy perspective, meanwhile based on the well experience of domestic similar oilfield, the result indi- cate that the flowlines shall be designed to maintained a temperature above PP plus 5℃.
