Abstract
A kind of magnetization anti-sticking screw pump of adhesion reducing and wax preventing, including：Bull stick（1）, oil pipe（2）, anchor（3）, screw pump stator（4）, screw pump rotor（5）, magnetizer（6）, centralizer（7）；It is characterized in that：In screw pump stator（4）Upper periphery is set there are one anchor（3）, in screw pump stator（4）The upper periphery of lower end is set there are one centralizer（7）, in screw pump stator（4）Periphery is uniformly provided with 2~4 magnetizers（6）.The utility model changes oil molecule, wax molecule and molecular structure water by magnetizer, and preferably playing the role of viscosity reduction prevents wax deposition and good antiscale property, extends service life and the time between overhauls(TBO) of screw pump, rate when improving the oil recovery of oil well.
Description
Technical field
The utility model is related to the pumping unit that recovers the oil in oil field development, a kind of specifically a kind of magnetization anti-sticking screw rod of adhesion reducing and wax preventing
Pump.
Background technology
Screw Pump of Oil Field producing well is relatively more at present, but screw pump oil production there is problems：First, heavy oil wells produce
In, viscous crude is earthward lifted to be conveyed with ground, and screw pump motor load is bigger, needs the motor that matched power is bigger；Second is that
Due to containing the impurity such as wax, sand in crude oil, concentrated on screw pump stator in screw pump operation process, wear screw pump, sternly
Screw rod pump seizure during weight, bull stick is twisted off, needs to carry out large repairs to oil well, seriously affects the normal life of screw pump oil well
Production.
Invention content
The purpose of this utility model is to provide a kind of magnetization anti-sticking screw pump of adhesion reducing and wax preventing, and above-mentioned prior art is overcome to exist
The defects of.
The technical solution of the utility model is achieved in the following ways：
The utility model includes：Bull stick, oil pipe, anchor, screw pump stator, screw pump rotor, magnetizer, centralizer；
It is characterized in that：It is set in screw pump stator upper periphery there are one anchor, the upper periphery in screw pump stator lower end is equipped with
One centralizer is uniformly provided with 2~4 magnetizers in screw pump stator periphery.
The screw pump stator is set as cylinder, is made of the stainless steel of 0cr26Ni5Mo2 magnetic conductions.
The magnetizer is set as circular ring shape, and outer diameter is less than casing inner diameter, and internal diameter is more than the outer diameter of screw pump stator, using height
Strong magnet makes, with screw pump stator hot pressing or Nian Jie one.
The centralizer is set as circular ring shape, and outer diameter is less than casing inner diameter, is uniformly set between upper surface and lower face
There is intercommunicating pore, with screw pump stator hot pressing or Nian Jie one.
Compared with the prior art the utility model has the following advantages：
Crude oil molecule, wax molecule and molecular structure water are changed by magnetizer, preferably playing viscosity reduction prevents wax deposition and prevent
The effect of fouling extends service life and the time between overhauls(TBO) of screw pump, rate when improving the oil recovery of oil well.

Specific embodiment
Further to disclose the technical solution of the utility model, made specifically by embodiment with reference to the accompanying drawings of the specification
It is bright：
The utility model includes：Bull stick 1, anchor 3, screw pump stator 4, screw pump rotor 5, magnetizer 6, is helped oil pipe 2
Positive device 7；It is set in 4 upper periphery of screw pump stator there are one anchor 3, the upper periphery in 4 lower end of screw pump stator is equipped with one
A centralizer 7 is uniformly provided with 4 magnetizers 6 in screw pump stator periphery.
In application the utility model, screw pump stator 4 and sand screen 8 time are used by anchor to the depth designed by oil pipe 2
Determine the fixation of device 3 and 7 righting of centralizer, screw pump rotor 5 is arrived in screw pump stator 4 for 1 time by bull stick, starts screw pump motor,
Screw pump rotor 5 starts to rotate, and the crude oil after being filtered by sand screen 8 is sucked by screw pump, and well head and defeated is given rise to through oil pipe 2
Enter surface gathering and transferring pipeline.The pressure on stratum arrives the casing pressure table of well head by the reflection of casing 9, centralizer 7 and anchor 3, explicitly
Layer energy.Crude oil molecule, wax molecule and molecular structure water are changed by magnetizer 6, preferably playing viscosity reduction prevents wax deposition and prevent
The effect of fouling extends service life and the time between overhauls(TBO) of screw pump, rate when improving the oil recovery of oil well.Sand screen 8 uses
Stainless steel or polytetrafluoroethylene (PTFE) make, and non-scaling, filter opening L will not be blocked, sand grains more than grain diameter 0.01mm can be blocked,
Screw pump sand card and abrasion are prevented, ensure that the normal production of oil well.
