Theory Research

This paper first studied the feasibility in application and advantages of the the full metal single screw pump by the method of theoretical research . Then the paper deducted the motion characteristics of the rotor around the stator and flow rate of the metal single screw pump .It is pointed that the center of the rotor profile is always located in the long shaft of the section of stator in any section .As the rotor rotates, the center of the rotor profile on this section takes straight reciprocating motion along the long axis of stator section .The results indicate that it exists feasibility in the designing and processing of full metal single screw pump. Thereby it provides theoretical basis for the application of full metal screw pump.

Mesh Technique

Compared with traditional screw pump,all-metal screw pump have more advantages in the oil extraction. In this paper, all-metal single screw pump's geometric model was made by PROE software; then the dynamic mesh technique was applied to mesh the model and constraint condition was applied in the ANSYS-FLUENT software. 3D flow field was numerical analyzed In that software, the impacts of screw speed on volume flow and volumetric efficiency were concluded, the conclusion can offer some valuable guidances to the all-metal single screw pump's design.

Abstract Unsteady 3D flow simulations on a twin-screw pump are performed for an assessment of the radial, circumferential and flank gap flow effect on the pump performance. By means of the overset grid technique rigid computational grids around the counter-rotating spindles yield a high cell quality and a high spatial resolution of the gap backflow down to the viscous sublayer in terms of y^+ < 1 . An optimization of the hole-cutting process is performed on a generic gap flow and transferred to the complex moving gaps in the pump. Grid independence is ensured, and conservation properties of the overset grid interpolation technique are assessed. Simulation results are validated against measured pump characteristics. Pump performance in terms of pressure build-up along the flow path through the spindles and volume flow rate is presented for a wide range of spindle speed and pump head. Flow rate fluctuations are found to depend on head but hardly on speed. By a profound assessment of the respective radial, circumferential and flank gap contribution to the total backflow, the importance of the most complex flank gap is pointed out. Backflow rate characteristics in dependence on the pump head and the pump speed are presented.

The Cost

Down-hole oil-water separation and reinjection in the same well system can reduce the cost of lifting the water and the ground pollution due to the treatment of production water, which can bring good economic and environmental benefits. By combining down-hole oil-water separation technology with surface driving single screw pump oil production technology, the author designed an innovative system of down-hole oil-water separation and reinjection in the same well. In this paper, the general structure, working principle and structure characteristics of the system are introduced. The structure composition and the connection method of each part are described, and the calculation method of basic parameters of the single screw pump in the system is given.
