PCP pump drainage system is mainly composed of the ground driving device, downhole PCP pump, anchor, frequency conversion control cabinet is composed of four parts. The whole work is by the motor through the driving device on the ground, underground oil pumping rod drives the rotor pump to complete.
Ground driving device: our company's ground driving device is the traditional dynamic sealing rod structure improvement for static sealing and installing spindle locking structure, greatly improving the sealing performance. The transmission mode is: big belt wheel motor drive gear shaft, the power of the motor through the gear shaft to the spindle. Sucker rod through the spindle hole and connected by the card in the upper end of the main axle flat square, drive rod, sucker rod and downhole PCP pump rotor connected, drive PCP pump works.
Downhole PCP pump consists of a rotor and a stator rotor section for single head screw is circular, the inner cavity of the stator is double headed screw; "S" in the cavity is formed between the stator and the rotor, because the rotor in continuous rotating cavity, "S" will continue to spiral, a new cavity formed by a spiral liquid below. At the upper end of the discharge, complete the lifting process. The machine is controlled by frequency conversion control cabinet and the PCP pump monitoring and protection.
The stator and rotor are connected to the ends of the oil pipe and the sucker rod. The surface driving equipment drives the rotor to rotate through the sucker rod, and lifts the downhole liquid to the surface.
2.The Advantage:
Generally speaking, the downhole screw pump is suitable for crude oil production with viscosity below 8000mPa.s, so most heavy oil wells can be applied.
The downhole screw pump does not cause air lock, so it is more suitable for oil and gas mixed transmission, but the free gas at the entrance of the downhole pump will affect the volumetric efficiency.
Downhole screw pump can be installed in the inclined straight section, and the equipment structure is simple, the area is small, the transportation and maintenance cost is low, so it is suitable for offshore oil production.
