Abstract
The utility model relates to a thermal production anticorrosive watering hollow pipe. A rod body has a hollow body; upper threads and lower threads are arranged at the upper end and the lower end of the rod body respectively; and an anticorrosive layer is arranged on the inner bore surface of the rod body. The anticorrosive layer arranged on the inner bore surface of the rod body is nickel plated phosphorus. A seal ring groove is formed on the outer threads. The anticorrosive layer arranged on the inner bore surface of a hollow oil pumping rod has anticorrosive property and can prevent corrosion of the inner bore surface. The anticorrosive layer has high surface smoothness and low liability of scaling. The thermal production anticorrosive watering hollow pipe can prolong the service life of the hollow oil pumping rod and improve the reliability of an oil pumping system, and has notable economic profit.
Description
Technical field
The utility model is the sucker rod that oil field pumping well is used, and is the anticorrosion water mixing hollow section of a kind of thermal recovery.
Background technology
The hollow oil pick-up tube that is used for hot water heating on the thermal production well is recovered the oil in the oil field and is used to drive the oil well pump reciprocating motion of the pistons.Present hollow oil pick-up tube endoporus is not handled, rough surface, and long-term flow of hot water in well is crossed easy fouling, corrosion, cause the application life of hollow oil pick-up tube short, the oil pumping system reliability is low, and the oil well production cycle is short, reduce output, increase input the oil well deficiency in economic performance.
Summary of the invention
The purpose of this utility model provides the anticorrosion water mixing hollow section of a kind of thermal recovery, improves the reliability of hollow roofbolt, increases the thermal production well production cycle, reduces workover cost.
The purpose of this utility model is achieved in that the body of rod is a hollow body, and there are last screw thread, following screw thread in body of rod two ends, and body of rod bore area has anti-corrosion layer.
Body of rod bore area anti-corrosion layer is a nickel plating phosphorus.
Seal groove is arranged on the external screw thread.
The beneficial effects of the utility model are: because the nearly bore area of hollow oil pumping has anti-corrosion layer, anti-corrosion layer has antiseptic property, can prevent the bore area corrosion, the finish height of anti-corrosion layer is not easy fouling, therefore, the utility model can reach purpose of design, hollow oil pick-up tube long service life can improve the reliability of oil pumping system, has remarkable economic efficiency.
Description of drawings
Accompanying drawing is the half sectional view of the utility model embodiment.
The specific embodiment
