Description
Technical field
The utility model belongs to petroleum technology field, more particularly, to a kind of new iso-stress hydro powered assembly.
Background technology
In drilling process, broken rock mode is that underground is hampered or bit freezing will seriously affect brill an important factor for influencing drilling speed
Well process, as current wellbore is more and more irregular, extended reach well drill mode faces more challenges.Reduce friction resistance
Lock of tool drilling in power, reduction drilling well, it is that current drilling engineering is in the urgent need to address to increase dynamic the pressure of the drill, improve conventional drilling efficiency
Problem, field practice show, the periodicity axial vibration appropriate to drill string, can effectively reduce in drilling process drilling tool and the borehole wall it
Between frictional resistance, improve the efficiency of breaking rock of conventional drilling, reduce conventional drilling lock of tool drilling, and increase dynamic the pressure of the drill, be suitable for
A variety of drilling modes such as extended reach well, directed drilling, horizontal drilling, vertical drilling, coiled tubing drilling, oil drilling, geology
The operations such as exploration all reach 7000 towards high temperature, high pressure, deep-well, particularly Tarim, Xinjiang, Offshore Operation well depth now
More than rice, traditional hydro powered assembly is similar to screw drilling tool motor or screw pump drive assembly, as shown in Figure 1, being rubber
Glue vulcanization forms rubber bushing in steel pipe housing, and the endoporus of steel pipe housing is circle, and the inner surface of rubber bushing is helical curve
Face, thus the radial direction interface thickness of rubber bushing is very uneven, the stator of this helicoid hydraulic motor is in rotor rotary work, rotation
Turn the part that the heat that friction produces is easily collected on rubber thickness, to make rubber swelling amount herein bigger than other positions, so turn
When son works inside it, stator premature failure is easy to cause, so as to reduce driver drive efficiency and service life, this practicality
Using a kind of pre- profile formula power housing, using the reserved helical openings between core and housing, in the spiral sky of this cooperation
The special rubber of resistance to oil base of injection in gap, so in the normal orientation of housing cavity curve, rubber bushing thickness be it is equal,
I.e. rubber bushing is to wait wall thickness structure, the generation of this failure conditions that can generate heat to avoid rubber bushing slub.
The content of the invention
The purpose of this utility model is to provide a kind of hydro powered assembly not easy to wear, long lifespan, the utility model
Purpose can adopt the following technical scheme that：Including power housing, the linear curve of inner wall of power housing, and in linearity curve inner wall
The upper setting wall thickness abrasive rubber such as one layer.
The technical solution of the utility model is：A kind of new iso-stress hydro powered assembly of the utility model, including it is upper
Box cupling, rotor, power housing, case bushing, lower box cupling, O-ring seal, determine valve, lower contact；The upper box cupling and it is described under connect
Hoop is the hollow structure that one end is equipped with taper thread, and power housing, power shell are connected between the upper box cupling and the lower box cupling
Internal side is spiral helicine hollow structure, is internally provided with rotor, and rotor is also helicoidal structure, and inner wall connects on the right side of lower box cupling
It is connected to and determines valve, determines the connection lower contact of valve right end.
The inner wall of the power housing is in linear curve.
The case bushing be line style curved inner wall inject one layer of uniform thickness spiral shape is wear-resisting, the rubber bushing of resistance to oil base
Set.
The rotor surface has plated the steel screw rod of one layer of chromium metal, effectively matrix can be prevented to be subject to erosion.
The rotor tip is coated with one layer of antifriction alloy with determining valve end.
The utility model has the advantages and positive effects of：
1st, the utility model is processed to the helicla flute of certain Curve, and rubber bushing due to the inner wall of stator
Possess the shape similar with stator, be tightly fitted on stator inner wall, heat localization effect will not be produced, and temperature is to influence stator
One of sensible factor of rubber bushing physical life, the heat that same wall-thickness stator can slow down rubber because of its good heat dissipation performance are old
Change, further improve the service life of hydroscillator, the energy of thin and uniform wall thickness rubber layer resistance to deformation during the motion
Power is good, thus single-stage pressure-bearing is high；The swelling of same wall-thickness stator rubber bushing, temperature rise uniformly, can preferably ensure the molded line of oscillator,
Sealing performance is improved, and the wear-resistance and oil-resistance base rubber of uniform thickness is set on inner wall, so that it is the same to reach swell increment when work is heated
Greatly, efficiency greatly improves, and not easy to wear, and the physical life of hydroscillator extends, and reduces the trip time, at present at home
Hydroscillator usage quantity is few, and the used drive for being substantially traditional rubber bushing, the wall thickness bushing such as seldom using
Dynamic assembly, therefore the product has filled up the blank of domestic oscillator type, to widely using for the deep-well after and drilling at the sea
Have great significance.
2nd, the suitable deep-well of the utility model, extended reach well, high angle hole, horizontal well, Multilateral Wells cluster well etc., and can be
The long period uses in oil-base mud, greatly improves drilling efficiency.
