Downhole Tools-manufacture,factory,supplier from China

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 large diameter pump designed and developed by Weima is to design the oversized pump for a given casing size well. The outer diameter of the plunger shall be larger than the inner hole of the tubing.

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.

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%.

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.

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.

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

Stem guide sleeves are standard on rod pumps.Used for righting valve stem.

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

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.

According to the characteristics of heavy oil wells, Weima uses the pressure of the tubing liquid column to assist the sucker rod to descend, and has designed several special henavy oil pumps.

The upper joint of the pump barrel is a standard part of the rod type oil pump.The upper part is connected with the stem guide sleeve and the lower part is connected with the pump barrel or lengthened.

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

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.
