SUBSURFACE SUCKER ROD PUMPS
TUBING PUMPS
The tubing pumps can be sunk into wells in sequence as follows: barrelis run down to the setting depth onthe tubing and then plunger with the standing valve on the rod string. For tubing of same diameter, tubing plumps are always of larger capacity than insert pumps. The tubing pump is simple in structure and applicable for wells not too deep and of higher production rate.
Tubing pumps are classified as THD pumps and THC or THM pumps. The standing valve of THC or THM pump can be hold and sealed by a mechanical or cup hold-down. Plunger together with standing valve canbe lifted out integrally for normal pump check, with the tubing remain intact. This makes the tubing pumps suitable for wells usually with short pump check intervals.
INSERT PUMPS
The insert pump can be connected to sucker rod on the surface and then lowered into the wells integrallythrough the tubing.Pump checks are easy and without the need of pulling and running the tubing. This makes it especially suitable for deep well applications.Reduced running time and make-and-breaks can surely enhance tubing working life. Insertpumps are clarified as mechanical and cup hold-down pumps by hold-down types or as top hold-down,bottom hold-down andtraveling barrel insert pumps by hold-down positions.SPECIALTY SUCKER ROD PUMPS
Specialty sucker rod pumps are applicable forsand,live or high viscous wells,slant wells,or for use in zonal production or casingless production.They have been used in many oilfields with good efficiency.
Various types of specialty pumps and accessories as follows can be designed and made for actual applications and upon client's request:
1.Plungers electroplated in deep well and thenforcefully honed on machines,with electroplated length up to 11m for plungers,rods and barrel items;
2.Optional chrome-plated plungers or Ni-Base coated plungers by spray welding processes;3.High precision valve balls and seats in various materials such as stainless steel,ceramic and carbide.
SUCKER RODS
Sucker rod, as one of the key component of rod pumping equipment, serves to transmit surface power or motion to downhole sucker rod pumps. Products and services are avallable as follows:
1. Grade C, D, KD, HL sucker rods and pony rods, drive rods, anti-side-abrasion sucker rods,pump rods, sinker bars, solid polished rods, special polished rods and inserted joint rods;
2. Grade T, KD and SM rod couplings in full size and slim hole diameters,adaptor couplings,anti-side-abrasion couplings.polish rod couplings and ultra-high strength couplings;3. Sucker rod centralizer,polish rod clamp;4. Sucker rod refurbishing.
