RockySea Petro Spiral Drill CollarIn directional drilling, due to the large deviated well and the large contact area between the drill collar and the borehole wall, problems like sticking and jamming are more likely to happen. The spiral drill collar reduces the contact area between the drill collar and the borehole wall, so it is widely used. Spiral drill collars are not listed in intl standards, but due to its practical value, many manufacturers have produced them.Description The function of
VIEW DETAILSRockySea Petro Desulfurization And Denitrification Oilfield Steam BoilerThe utilization rate of lime can be improved and the cost of desulfurization can be saved by adopting the integration of desulfurization and dust removal.The regeneration of absorbent, desulfurization slag and precipitation are carried out outside the tower, which reduces the possibility of scaling in the tower.With NaOH desulfurizer, the circulating solution is basically NaOH aqueous solution, and there is no corrosion and blockag

When using the fixed screw type, first insert the sleeve, then insert the screw and use a hammer to strike.2. The conventional stop ring should be inserted into the sleeve first, and then the screw should be tightened with a wrench.3. Snap on the locking ring, directly attach the locking ring to the sleeve, lock it with a pin, and then tap in the screw.TypeThe stop rings of

The tubing pump parts should be inspected several times during the processing procedure.Best tubing pump manufacturer in ChinaRockySea Petro also developed the downhole pumps with various processes of boronizing, nitriding, chrome plating, tungsten plating for special well conditions.Some key point
VIEW DETAILSRockySea 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
