Introduction of heavy oil recovery downhole pump:
The floating valve pair of our heavy oil recovery downhole pump adopts a strong opening and closing structure, with a large flow channel area, which is convenient for the exploitation of heavy oil and can prevent gas lock. The fixed valve of the heavy oil recovery downhole pump adopts tungsten carbide alloy material, which improves the timeliness and reliability of the valve pair closing. The working cylinder is added to the outside of the heavy oil recovery downhole pump to prevent the deformation of the pump cylinder during operation and production. It is suitable for deep wells. The heavy oil recovery downhole pump adopts a hanging method, which can automatically adjust the center and reduce the possibility of pump jamming. It has a certain adaptability to inclined wells. The heavy oil recovery downhole pump is suitable for the exploitation of gas wells, inclined wells and deep heavy oil wells (viscosity below 2000Mpa.s).
Advantages of sucker rod pump:
1. The valve in the sucker rod pump adopts a mechanical forced opening and closing structure design. The specially designed guide pin and reinforced spring make the opening and closing no longer rely on a single pressure difference, avoiding the common problem of traditional free valves stopping the pump due to "gas lock" caused by gas entering.
2. The key opening and closing components of the sucker rod pump are made of tungsten-cobalt alloy (hard alloy) and are precision-machined. They are corrosion-resistant and have high impact resistance. The normal operation cycle of the sucker rod pump is extended by more than 3 times, and the maintenance interval is extended from the traditional 3 months to 9-12 months.
3. The sucker rod pump adopts an automatic self-aligning design, a universal joint floating structure is added to the tail end of the pump barrel, and the plunger adaptively adjusts the center position to reduce the probability of eccentric wear and rod breakage, extending the life of the sucker rod pump by 20%-30%, especially in the medium and deep inclined wells and directional wells.
4. The flow channel, valve seat, and valve core of the sucker rod pump are all enlarged (15%-20% higher than conventional pumps), and streamlined transitions and chamfers are used, with less resistance to oil passing. The pumping volume per unit time is increased by 15%-25%.
5. Sucker rod pump can achieve effective pumping at lower power by reducing starting resistance (low pressure difference opening and closing) and optimizing plunger matching accuracy (extremely small leakage), while reducing the mechanical resistance in the up and down strokes of the sucker rod. The energy saving effect can reach 10%-18%, the motor power consumption is lower, the wear of the rod and pipe system is reduced, and frequent maintenance is reduced.
