Downhole screw pumps

Surface Drive and PC pump (Progressive Cavity Pump) is a kind of high-efficiency and energy-saving artificial lift system, which is composed of surface drive and downhole PC pump. Surface drive suspends and rotates rod string and power is then transmitted downhole, which in turn drives the PC pump. PC pump consists of two parts: rotor and stator. The high strength, chrome-plated rotor is the only moving part of PC pump. Stator is a kind of tube with elastic synthetic rubber molded inside. A variety of elastomeric is available for different applications. When rotor rotates in the stator, a series of sealed cavities are formed and these cavities move axially from the intake end to the displacement side. When one cavity disappears at the displacement side, a new cavity is formed at the intake side. Trough continuous formation, motion and disappearance of these cavities, fluid is then brought to the surface. Owing to the unique features, the surface drive and PC pump finds wide applications in oil fields. They are strongly recommended for high viscous, sandy, gassy oil besides most well conditions.

Electric submersible progressing cavity pump

Wroking Principle：The submersible cable is used to transmit power to the submersible motor, and the submersible motor (permanent magnet synchronous motor) directly drives the PCP, and the well fluid is lifted to the ground by the PCP.

Rod pumps

The rod pump is suspended inside the tubing by the support joint, which is suitable for high temperature deep well and inclined well oil exploitation, and is resistant to corrosion and high temperature. Downhole operation is convenient, economical and practical, and can reduce the operating cost of the oil field by more than 50%. Customized design according to customer well conditions.

Pumping units

Pumping unit is a kind of machinery and equipment for the exploitation of oil, commonly known as "kowtow machine". The pumping unit is the most important lifting equipment in the rod pumping system. According to whether there is a floating beam, it can be divided into a floating beam pumping unit and a non-floating beam pumping unit. The basic characteristics of the beam pumping unit are simple structure, easy manufacturing and convenient use, especially it can operate all weather in the oil field for a long time and is reliable in use. Therefore, it is still the most widely used pumping unit, although it has the disadvantages of large acceleration of the suspended point movement of the donkey head, poor balance effect, low efficiency, large volume and bulky at long strokes. Our company can provide various types of pumping units, and can be customized according to customer needs!

Complete wellhead devices

The complete wellhead device is a device installed at the wellhead to control the pressure and direction of gas and liquid (oil, water, etc.) fluid, suspend casing and tubing, and seal the tubing and casing and the annular space of each layer of casing in oil and natural gas drilling. It is generally composed of casing head, tubing head, blowout preventer group, four-way and by-pass pipe fittings. Oil trees and gas trees also belong to wellhead devices. The performance of wellhead equipment is related to the safe and effective production of oil and gas Wells. The future of the oil industry has higher requirements for the reliability and control of wellhead devices and valves, which promotes the continuous improvement and development of wellhead devices. For the whole wellhead device, the improvement of the wellhead device mainly focuses on the reduction of size and weight, even the portability and flexibility; In the form of structure, mainly pay attention to the improvement and development of gate valves, increase the promotion of the use of wellhead devices, and carry out detailed analysis and research on products.
