Advantages of Screw Pump Oil Production Technology
In the working process of screw pump, its volume efficiency is inversely proportional to pressure. The higher the pressure is, the lower the volume efficiency is. When the pressure at the pump mouth is the same, the deeper the pump goes down, the lower the flow pressure is, the higher the crude oil output will be. Its performance follows the characteristics of heat conservation, mass conservation and energy conservation. Compared with other oil production equipment, screw pump has many advantages, which is also an important reason for the rapid development and wide application of this technology.
First of all, the screw pump structure is relatively simple, energy consumption is not high, installation is simple, less investment, can maximize the cost of oil recovery price.
Secondly, the screw pump follows the characteristics of heat conservation, mass conservation and energy conservation, and has almost no flow pulsation. Its axial flow is continuous and very stable. There is little inertia loss caused by mechanical transmission and inertia of liquid column. The volume efficiency of the pump can be up to 90%. The screw pump is one of the systems with the lowest energy consumption and the highest efficiency in the oil production machinery system.
