PRODUCTION DESIGN FOR HEAVY OIL INJECTION GAS WELLsolution

Design 1. All Metal Vane Pump

With its special structure, materials and supporting tools, the all-metal special vane pump makes the heavy oil injection wells have a longer production cycle, lower production cost and more convenient production and maintenance.

Product Advantages:

1. Uniform flow and stable operation;

2. With blade self-compensation function: less leakage, long life;

3. Strong self-priming ability, suitable for heavy oil extraction;

4. Temperature resistance 325 ° C, suitable for thermal extraction wells;

5. Small running resistance, high efficiency, energy saving;

6. The gas has no effect on the operation of the system;

7. Extend the gas injection cycle.

Design 2. Hydraulic Feedback Pump


Equal to two pumps with different diameters in series, the large one is at the top and the small one is at the bottom, all the valve balls are designed in the plunger. The plunger can generate feedback force and accelerate the plunger down, which is suitable for cold extraction and steam injection thermal recovery of heavy oil wells.

Product Advantages:


1. It is possible to carry out steam injection thermal recovery without moving the column, and it is convenient to transfer pumping and injection;

2. The downward load is large, the plunger descends fast, the pump efficiency is high, and the anti-abrasion is prevented;

3. Lifting the plunger out of the pump barrel, which can perform operations such as washing wells and draining oil;

4. Temperature resistance is up to 325 ° C, can be applied to thermal extaction wells;

5. The structure is reliable, easy to operate, the average pump detection cycle can reach more than two years.

Design 3. Bias Valve Type Hydraulic Feedback Pump

The bias valve type hydraulic feedback pump is equivalent to two pumps of different pump diameters in series. The large pump is on the upper and the small pump is on the lower. Compared with the hydraulic feedback pump, the standing valve is installed on the side of the barrel. The liquid resistance is small, the plunger can generate feedback force and accelerate the plunger down, which is suitable for cold extraction and steam injection thermal recovery of heavy oil wells.

Product Advantages:

1. It is possible to carry out steam injection thermal recovery without moving the column, and it is convenient to transfer pumping and injection;

2. The downward load is large, the plunger descends fast, the pump efficiency is high, and the anti-abrasion is prevented;

3. Lifting the plunger out of the pump barrel, which can perform operations such as washing wells and draining oil;

4. Compared with the hydraulic feedback pump, the inlet resistance is small and the pump efficiency is high;

5. Temperature resistance is up to 325 ° C, can be applied to thermal extaction wells;

6. The structure is reliable, easy to operate, the average pump detection cycle can reach more than two years.


Design 4. Long Plunger Injection Pump

The long plunger injection pump consists of a long plunger and a short pump barrel. The pump barrel is designed with a steam injection passage. The plunger can be connected with lowering the plunger, injection steam and thermal extraction for heavy oil.

1. It is possible to carry out steam injection thermal recovery without moving the column, and it is convenient to transfer pumping and injection;

2. The downward load is large, the plunger descends fast, the pump efficiency is high, and the anti-abrasion is prevented;

3. Temperature resistance is up to 325 ° C, can be applied to thermal extaction wells;

4. The structure is reliable, easy to operate, the average pump detection cycle can reach more than two years.
