475(120.65mm)THM Tubing Pump

Our company can produce all kinds of non-standard large-diameter pumps according to the user’s demand. At present, our company can produce 413 (Φ 105), 425 (Ф 108), 475 (Ф 120), 531 (Ф 135) and other large-diameter pumps, of which 120 large displacement corrosion-resistant pumps are specially designed and manufactured by our company for shell Netherlands company, with a pump diameter of 120.65mm, a maximum stroke of 9.2m, and a daily liquid output of 151-452m3.

Characteristics

1.Adopt spray metal plunger, the accessories are made of special materials and heat treatment. It has good wear resistance and corrosion resistance

2.The traveling valve is lined with a hard layer which improves the wear resistance and impact resistance of the valve cover.

3.Titanium alloy ball and hard alloy valve seat, high hardness, wear resistance and strong corrosion resistance.

4.The traveling valve is forced to close which effectively improved the fullness.

5.The standing valve can be fished which is easy for pump inspection.

Application:

1000m horizontal well.The installation section has a slope of 80 degrees.The well fluid contains 1000ppm H2S and CO2. The pressure in the pump is 9.5Mpa. The temperature is 40-220℃, and it does not contain sand.

Double-acting sucker rod pump

A special structure is used to complete the two oil suction and two oil discharge actions in a reciprocating stroke, which can realize a double-layer recovery.

Features

It is divided into two working chambers by sealing device which can completes two oil suction and two oil discharge actions in a reciprocating stroke.

1)Compared with ordinary single-acting pumps with the same diameter, the theoretical displacement is increased.

2)It can realize double-layer recovery.

Application

1)The oil wells with ordinary oil pumps.

2)The oil wells can realize double-layer recovery.

3)The oil wells with high fluid production.

Dual Channel oil well pump

Features

1.The special structure forms two working chambers which completes two oil suction and two oil discharge actions in a reciprocating stroke that increases the theoretical displacement compared to ordinary pump.

2.The two working chambers are completely separated from the oil suction and discharge which ensure the two layers of fluid with different physical properties are strictly separated and eliminate interference between layers

Application

Oil wells or test wells where two oil layers need to be produced at the same time and the produced fluids do not interfere with each other can be measured and calculated separately.

Self-contained complete insert pump

Features

1)Add on-off tools and oil drain to the oil pump.

2)The operation of on-off tools is simple and convenient.

3)This pump adopts reasonable matching technology to prevent the operation failure caused by the improper matching of the pump.

Application

1)The oil wells with ordinary oil pumps.

2)The oil wells used HDPE tubing string.

3)The oil wells with high fluid production.

 

Triple-acting sucker rod pump

A special structure is used to complete the three times oil suction and three times oil discharge actions in a reciprocating stroke which can realize a double-layer recovery .

Features

1)The pump is divided into three sealed chambers A, B and C by a special device which all have the functions of suction and discharge.

2)The pump is equiped with on-off tools and operation is simple and reliable.

3)The biggest feature:It works with 57 pump load but with 82.5pump displacement which save energy greatly.

Application

1)The oil wells with ordinary oil pumps.

2)The oil wells can realize double-layer recovery.

3)The oil wells with high fluid production.

4)It is especially suitable for deep wells with large discharge capacity and it can replace 83 oil pumps.
