Oil Well Tubing Pump For Some Large Production Wells
Large production well tubing pump description:
Main parts process and material:
Pump barrel: plain carbon steel plating (A1), ordinary carbon steel carbonitriding (B1), ordinary carbon steel carburizing (B2), low alloy steel nitride (B5).
Plunger: 1045 steel spraying (B1), 1045 steel spraying (B2), 1045 steel chrome plating (A1), 1045 steel double chrome plating (A2).
Valve ball and seat: stainless steel (A1), cobalt chromium (B2), tungsten carbide (C1), nickel and carbon compounds (C2), titanium carbide (C3).
Other accessories: plain carbon steel, low alloy steel, stainless steel, brass and other materials.
For this type of pump, the barrel is put in the well to the designed depth with tubing. And then put the plunger into the barrel with sucker rod. Given the tubing size, the bore of the tubing pump is larger than that of the rod pump, so the pump rate is higher. According to seating mode, the rod pump can be divided into three types: THC pump (Stationary Heavy Wall, Cup Seating, Tubing pump), THM pump (Stationary Heavy Wall Mech. Seating, Tubing Pump) and THD pump.
