Downhole Tools-manufacture,factory,supplier from China

The drawpipe is a standard part of the moving bobbin pump.Material selection is seamless steel tube, the surface can be chrome plated or other anticorrosive hardening treatment.

The linear motor carries out reciprocating movement under the control of the ground control cabinet, to drive the plunger of the sucker rod pump reciprocating, so as to complete the lifting well liquid to the ground via tubing.

The fixed valve puller provides a device whereby a tubular oil pump can be used to carry out fixed valve maintenance operations by simply lifting the sucker rod string.

The ground device has a simple structure and is easy to install, and can be directly connected with the wellhead casing four-way, and covers small area.

Seat plugs are standard on the plunger of a pump. For jacking traveling seat.

The stem reducer joint is a standard part of the sucker rod pump and connects the upper stem of the plunger to the rod string.The connecting part with the valve stem is the key to the structure of the product. The more likely problem to occur is the breaking off of the connecting valve stem.Therefore, its material’s selection and structural strength’s design need to fully consider the product’s operating environment.

The overall appearance of the motor is flat type, the internal stator is independent centralized winding mode

The systems design, material composition and metallurgical processing have been patented and proven in the USA, Canada, Mexico, China and other countries in preventing and removing Corrosion, Scale, Paraffin, Asphaltenes.

Double Acting Pump designed and developed by Weima is used for well with high reservoir pressure and sufficient liquid supply, especially those where conventional pumps cannot meet the displacement requirements.

Rod, Stationary Thin Wall Barrel, Bottom Mechanical Anchor Pump

Double Acting Pump is used for well with high reservoir pressure and sufficient liquid supply, especially those where conventional pumps cannot meet the displacement requirements.

Hydraulic station produces hydraulic oil with high pressure, drive the hydraulic cylinder operation through the hydraulic pipe line

Tubing pump with pin end plunger, tap type puller, cup anchor standing valve

The upper open bonnet is standard on tubular pumps.The upper part is connected with the sucker rod string, the lower part is connected with the plunger, and the traveling valve is placed in it.Material selection and structural strength are the key factors in product design.In order to strengthen the protection of the valve hood, there are alloy lined valve hood designed for thermal production and high flushing oil Wells.There is a rubber lined valve cover designed for cold production and high stroke oil Wells.

Rod, Stationary Heavy Wall Barrel, Bottom Mechanical Anchor Pump

The two-stage anti-gas rod pump designed and developed by Weima adopts a slender upper plunger connect with a larger diameter lower plunger in series to divide the lower pump barrel into upper and lower two working chambers.

The hydraulic feedback pump designed by our company can exploit crude oil with viscosity ＞ 4000mpa*s.

Hydraulic drive oil production system includes: control cabinet, hydraulic control device, liquid transmission pipe, hydraulic drive propeller and plunger pump.

The eccentric pump designed by our company can exploit crude oil with viscosity＞4000mpa*s.

In this regard, Weima designed and developed a long plunger sand setting pump that can be used in wells with high sand content and interstitial wells with sand content of less than 3%.
