Long plunger injection production downhole reciprocating pump

It is suitable for single-well requires steam injection for thermal recovery.

It is a pump can realize simultaneous steam injection and recovery and anti sand stuck.

It is suitable for heavy oil wells with single well steam huff and puff, and can be used for pumping and injection and sand control.

Sanjack all-metal, heavy-oil tubing pump maximizes flow area throughout the pump.

Increased fluid passage (up to 44 percent) improves pump filling and plunger fall, for higher production of heavy oil.

The pump combines heavy-duty construction with the largest bore possible for any given tubing size to maximize production.

The one-piece barrel eliminates joints susceptible to failure under working loads and is precision honed from end to end to ensure a perfect bore for the plunger and to maximize pumping efficiency.

These pumps are recommended for the following applications:

• Heavy-oil wells
• Wells where greater capacity is needed in a given tubing size
• Wells of moderate depth with severe pumping conditions
• Wells with scale problems
• Deep wells

Features, advantages and benefits of these pumps include:

• Maximized flow area throughout the pump, together with stroke-through design, optimizes heavy-oil recovery efficiency.

• Heavy-wall, one-piece barrel with special barrel couplings provides a positive seal and superior assembly strength and rigidity to perform in the harshest environments.

• Full-barrel, stroke-through design has the largest possible bore for any tubing size to maximize production.

• Components are offered in a broad range of materials so that pumps can be tailored to any environment for maximum cost efficiency and pump life.

• A variety of exclusive pump accessories extends the range of pump applications to provide greater versatility, adaptability and value.

Features:

1) Dual-purpose injection and extraction: the conversion of injection and extraction is simple and reliable.

When steam is injected, you only need to lower the plunger assembly to the bottom to expose the steam injection hole to inject steam.

After steam injection, lift the plunger to cover the steam injection hole to turn.

Pumping can give full play to the thermal recovery effect of steam injection and reduce oil recovery costs.

2) Sand control card: The short pump barrel and long plunger structure are adopted.

During normal oil pumping, the plunger is always outside the pump barrel, which can reduce the occurrence of sand jam plunger.

3) The steam injection hole has an oil drain function:

During operation, a plunger is provided, and oil can be drained without any auxiliary tools, ensuring safe and civilized production at the operating well site and saving operating costs.

Application:

Heavy oil wells with single well huff and puff steam injection production.
