Abstract: Systematical technology reformation and optimization measures have been taken for Korla original pump station, pressure-reducing station and Shanshan terminal pump station in Korla-Shanshan oil pipeline. These measures are that in original station 3 pumps in 2-operation and 1-backup are changed into 1-operation and 2-backup, which fully meets the requirement of pump's suction pressure; in the pressure-reducing station the 3rd pressure reducing valve is installed which can effectively avoid plugging of impurity in crude oil transported; in the terminal station, an automatic oil loading process is implemented.
