Abstract: Based on the design and selection of a mixed transportation pump in an oil and gas field in Bohai,the main technical parameters considered for the selection of mixed transportation pumps are introduced. By comparing specific engineering selection examples,the process and methods of optimizing the selection of mixed transportation pumps are introduced. At the same time,the problems of pump operation and maintenance and the selection principle of pipeline filter are summarized,which provides a reference for how to simplify pump operation and maintenance on unmanned platform.

Key words: mixed transportation, parameters, stability
