Surface Drive and PC pump
Surface Drive and PC pump (Progressive Cavity Pump) is a kind of high-efficiency and energy-saving artificial lift system used for oil production industry, 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.
Main Advantages
1. Wide Well Fluid Range
Besides normal exploitation of conventional oil, the surface drive screw pumps
can be used to viscous oil well with the viscosity≤8000mPa·s without taking oth
er measures, including viscosity up to 60000mPa·s under measure of electric h
eating, watering, mixing viscosity reducer and so on, high wax bearing crude oi
l and high sand cut oil for the stator has resilience to sand.
2. No Gas Lock
The surface drive screw pumps can make the fluid move continuously and even
ly, so solution gas can not be released out. At the same time, it’s impossible for
gas lock due to no valves in the pump.
3. High Efficiency
System efficiency can be up to 70% for there are few moving parts, no valves
and complex channels, little oil flow interference and low hydraulic loss.
4. Uniform Flow and Easily Adjusted
The surface drive screw pumps could be adjusted the pump flow easily by chan
ging rotate speed of surface drive equipment.
5. Wide displacement Range
100rpm, daily production can be 1.59~380m3/d and more by increasing rotate
speed.
6. Simple Operation and Low Cost
Simple surface equipment, compact design and low cost so the pump has the
advantages of simple operation, little maintenance and lower work cost.
