RockySea Petro Mud PumpDescriptionIn the operation of using rotary drilling method to drill oil and natural gas wells, the drilling reciprocating pump is used to pump drilling fluid, i.e. mud, to circulate and flush the well. During drilling, the mud pump injects mud into the wellbore along with the drill bit, playing a role in cooling the drill bit, cleaning drilling tools, fixing the wellbore wall, driving drilling, and bringing rock cuttings back to the surface.So drilling pumps are usually

VIEW DETAILS
Flexing: An optional outside profile can be machined to reduce the collar rigidity if required.
Internal bore treatment: This option generates a compression level of at least 60,000 PSI at a given depth. This provides the collar with an excellent resistance to stress corrosion cracking.
Pin stress relief groove and box boreback: An pin stress relief can be used on all drill collars and downhole tools. It is a recommended option in situations where fatigue can occur as a result of bending. By removing unengaged threads in the high stress areas of the drill collar connection, it is less likely to crack due to fatigue because the bending will take place in the area of the connection with smooth surfaces that are free of stress concentrations.
Optional slip and elevator recesses are available to improve handling and safety. These two features can be used together or separately.
