Extensión de durabilidad de pistones de bombas de fractura hidráulica mediante el empleo de tecnología de nitruración por plasma y PVD

ABSTRACT Hydraulic stimulation technique consists of "fracturing" the formation (rock reservoirs) through pumping a fracturing fluid downhole. This operation is performed by using hydraulic fracturing pumps. The pistons of these pumps are mechanical components performing the intake and compressing fracture fluid by reciprocating action. During this alternative cycle, the entry of fine sand in the gap between piston surface and seals causes localized wear of the piston. Nowadays, commonly used hardening Technology for manufacturing these components is Thermal Spray, which has specific technical...
