Development Trend and Key Technologies of Hydraulic End of High-Power Fracturing Pump
As the development of unconventional oil and gas wells is increasingly difficult in China,the re-quirements are raised for the service life of hydraulic end of high-power fracturing pump in continuous fracturing op-erations with high power,ultrahigh pressure,and large displacement.The research and development of long-life hydraulic ends and their vulnerable parts are of great significance for continuous large-scale fracturing operations with reduced engineering costs and labor intensity.In the paper,the technologies of high-power fracturing equip-ment and fracturing pump in China and abroad were introduced,and the valve housing,pump valve and packing seal at hydraulic end of fracturing pumps were elaborated.By analyzing the insufficient adaptability of the hydraulic end under continuous large-scale fracturing operations in ultra-deep layers,the development trend of the hydraulic end of high-power fracturing pumps was presented.Finally,based on finite element simulation analysis,technolo-gies and products were developed for the structure optimization of key parts,material selection and process im-provement of the hydraulic end.Field application demonstrates that the service life of the valve housing has been increased by 400-600 hours,the service life of the pump valve nearly doubled,and the service life of high-per-formance packing more than tripled.The research conclusions provide reference for the iterative upgrading and de-velopment of hydraulic end of high-power fracturing pump.
