稠油凝点高、黏度与密度大，热采地面集输难度大。中国稠油热采集输能耗高、热能综合利用率低、效率低，总体工艺技术水平较低。针对含水高、产量较低的稠油区块，提出采用注采合一污水回掺集输，电动选井多通阀集油计量，过热蒸汽吞吐，蒸汽锅炉高温烟气及热油余热利用等稠油集输新工艺、新技术和密闭电动选井多通阀配汽管汇、计量接转站及注汽系统相结合的二级布站、一体化建站的高效低耗集输系统，实现稠油地面集输高效、低耗，提高中国稠油集输工艺技术水平。

Due to high freezing point, high viscosity and density of heavy oil, it is difficult to conduct thermal recovery and surface gathering and transportation. Domestic heavy oil thermal recovery and surface gathering and transportation process is relative backward due to its high energy consumption and low multipurpose utilization rate of thermal energy. With continuous enlargement of viscous crude oil field development scale in China, problems existing in traditional gathering and transportation technologies become increasingly obvious. Especially for heavy oil blocks with low production and high water cut, new techniques and technologies shall be developed and applied speedily so as to improve surface thermal recovery. Analyzed are characteristics of heavy oil in domestic heavy oil blocks and proposed are some specific new techniques and technologies for heavy oil gathering and transportation process improvement.
