As a new technology, progressing cavity pump(PCP) directly driven by low-speed high-torque submersible permanent magnet synchronous motor(SPMSM) is applied to oilfields gradually. In order to evaluate the performance and reliability of this new system and serve practical application and teaching simultaneously, a set of the experimental platform for the new type oil production system is developed. It mainly includes the unit of PCP directly driven by SPMSM, pipeline circulation system, control system and parameter acquisition system. The design, processing, installation and testing of the experimental platform are completed, and the test results show that both the SPMSM performance and system performance can be tested effectively with different working conditions and then the validity of optimization design of SPMSM can be verified. The experimental platform has been used for directly driven PCP experimental teaching and the organic combination of theory and experiment teaching is realized. Thus, students can deeply understand the new oil extraction equipment and process, so that it improves their experimental and innovation ability.
