Introduction of annulus thermal recovery pump oil well:
Annulus thermal recovery pump oil well adopts large-caliber long-stroke pump barrel and plunger, which effectively increases the liquid production. A special disconnector for large pumps is used to complete the disconnection of the plunger and the sucker rod. The upper oil outlet valve and the lower part of the plunger are processed with sharp-angle scraping edges. During the reciprocating motion of the plunger, the annulus thermal recovery pump oil well continuously removes the scale and sand particles on the inner wall of the pump barrel, reducing and avoiding sand jams in the oil pump.
Annulus thermal recovery pump oil well is suitable for pumping heavy oil and super-heavy oil under special conditions such as high temperature and sand content, and heavy oil recovery sucker rod pump is successfully solves the problem of super-heavy oil extraction in China.
Advantages of high temperature heavy rod pump:
1. The high temperature heavy rod pump features extremely tight tolerances between the long plunger and short liner. Combined with a pointed bushing and sand scraping design, this pump removes sand and scale with each stroke, reducing pump sticking and sand blockage.
2. The high temperature heavy rod pump utilizes a hollow structure, allowing for upper and lower hollow sucker rod connections and cable access. The plunger and retaining valve can be lifted out without interrupting the tubing string, facilitating pump inspection and maintenance.
3. The high temperature heavy rod pump utilizes a traveling valve and centering valve with a mechanical ring valve, offering sensitive operation and tight sealing, ensuring stable and efficient pumping.
Structural diagram of heavy oil recovery sucker rod pump:
The core structure of steam thermal rod pump includes:
Barrel coupling: an important connection between the pump barrel and the sucker rod, usually a threaded connection structure.
On off connector for large pump: a disassembly connector suitable for large-size or deep-well oil pumps.
Sand scraping blade: installed near the plunger, used to remove sand and impurities in the inner wall of the pump barrel or the pump cavity.
Flow Valve: located above the plunger, opened when the plunger is on the upstroke and closed when the plunger is on the downstroke.
Piunger: a core moving part, usually sprayed with nickel-based alloy or hard chrome plating on the surface to improve wear resistance and corrosion resistance.
Flow valve: an auxiliary flow valve, an optional configuration, used to supplement and regulate liquid flow, suitable for multi-plunger structures or special working conditions that require segmented suction.
Barrel: the pump barrel not only bears the pressure of the liquid column, but also cooperates with the plunger to achieve sealed suction,
Inflow Valve: installed at the bottom of the pump barrel, opened when the plunger is on the downstroke and closed when the plunger is on the upstroke.

FAQ of steam thermal rod pump:
Q1: How does the steam thermal rod pump deal with the high viscosity resistance of super heavy oil?
A: The plunger of the steam thermal rod pump has a built-in electric heating system (380V/15kW, viscosity reduction of 85%), and a chemical viscosity reducer injection interface (maximum injection pressure 35MPa).
Q2: What is the maximum pumping depth of the steam thermal rod pump?
A:The standard configuration of the steam thermal rod pump is suitable for wells ≤2800m deep, and the special reinforced version can reach 3500m (need to be used with HY-grade sucker rods).
Q3: What is the replacement cycle of the scraper blade of the thermal recovery sucker rod pump?
A: The life of the tungsten alloy scraper blade of the high temperature heavy rod pump is ≥ 2 years (calculated based on 1000 strokes/day). The replacement of the high temperature heavy rod pump only requires the removal of the plunger module.
