Axial Force Studies of ESPCP System Based on Triz Theory

Abstract:

The configuration characteristics and actual working condition of the downhole unit of existing electrical-submersible-motor driven progressing cavity pumping (ESPCP) system are analyzed in detail. Appling the methods and the main tools of Triz theory, conflicting analysis is performed for the axial bearing capacity affecting submersible depth and operational lifespan of downhole unit. The parameters of physical and technical contradictions are standardized. Appropriate principles of invention are selected through contradiction matrix analysis and a more reasonable innovation design project of the ESPCP system configuration is developed. As such, the axial bearing capacity of downhole unit has been effectively improved.
