Abstract
The invention relates to a petroleum exploitation machinery, in particular to a specific oil well pump for a horizontal well. The specific oil well pump for the horizontal well comprises a pump cylinder, a plunger assembly and a fixed valve assembly. The plunger assembly comprises a plunger connector, a plunger, a valve ball valve seat and a plunger inner pipe. The valve ball valve seat adopts a cone-shaped ball and a cone-shaped seat, and the cone-shaped ball and the cone-shaped seat work in conjunction. The plunger is arranged in the plunger inner pipe in a sleeving manner. The upper end of the pump cylinder is hung in the air and the lower end of the pump cylinder is connected with the fixed valve assembly. The upper outer wall of the fixed valve assembly is connected with a connector and the upper inner wall of the connector is connected with a force bearing outer pipe. According to the specific oil well pump for the horizontal well, the force bearing outer pipe is arranged outside the pump cylinder, when the oil well pump is working, the annular space between the pump cylinder and the outer pipe would be filled with oil liquid, and the internal-external pressure difference is balanced, so that the working environment of the pump cylinder is greatly improved, the reduction of the pump efficiency caused by the increase of the leakage volume is avoided, at the same time the valve ball valve seat of the plunger adopts a cone-shaped valve, so that the situation that the valve ball valve seat of the horizontal well can not be sealed is avoided.
Description
Technical field
The present invention relates to a kind of oil exploitation machinery, more particularly to a kind of horizontal well Special oil pump.
Background technology
China's many oil fields have been enter into middle and late stage exploitation, drop in formation pressure, cause many oil fields to have to use little pump
Deep pumping technique.But the intensification hung along with pump, the working environment of oil well pump is more severe.As a example by Zhongyuan Oil Field, the most a lot of oil
The down-hole pump degree of depth more than 2000 meters, down-hole pump barrel inside and outside differential pressure closely 20MPa, the highest.For these reasons, pump barrel exists
Under the effect of inside and outside differential pressure, oil pumping barrel can be caused to produce so-called " ballooning effect ", make oil well pump produce gap leaking loss, pressure
More wide arc gap leakage is the biggest, makes the pump efficiency of oil well pump reduce.
Summary of the invention
It is an object of the invention to provide a kind of working environment being effectively improved oil well pump, decrease actual wastage
A kind of horizontal well Special oil pump.
The technical scheme is that
Horizontal well Special oil pump, including pump barrel, assembly for plunger and standing valve assembly, described assembly for plunger include plunger connector,
Plunger, valve ball valve seat and plunger inner tube, valve ball valve seat uses taper ball and conical seat, taper ball and conical seat cooperating, post
Plug sleeve is in plunger inner tube；Pump barrel upper end is unsettled, and pump barrel lower end connects standing valve assembly, and standing valve assembly external wall of upper portion connects even
Joint, jointing upper inside wall connects load outer tube, and load outer tube upper end outer wall connects outer tube top connection.
Described pump barrel upper end connects centering ring.
Described standing valve assembly includes reducer union, righting rod, spring, wiper block, standing valve cover and standing valve joint, becomes
Drive connector top inside and outside wall connects pump barrel and jointing respectively, and reducer union lower end connects standing valve cover, standing valve cover lower end
Connecting standing valve joint, standing valve cover top and reducer union bottom are respectively provided with wiper block, and righting rod passes two wiper blocks,
Being cased with spring outside righting rod, spring is between two wiper blocks.
The present invention arranges load outer tube outside pump barrel, during oil well pump work, will be filled with oil in pump barrel and outer tube annular space
Liquid, inside and outside differential pressure balances, substantially improves the working environment of pump barrel, decrease actual wastage, it is to avoid because of the increasing of wastage
Adding and cause the generation of the reduction of pump efficiency, the cone valve of plunger valve ball valve seat use simultaneously avoids horizontal well valve ball valve seat can not be close
The situation of envelope.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
1 outer tube top connection 2 centering ring 3 load outer tube 4 pump barrel 5 assembly for plunger 6 standing valve assembly
7 plunger connector 8 taper ball 9 conical seat 10 plunger 11 plunger inner tube 12 connecting rod 13 reducer unions
14 righting rod 15 spring 16 wiper block 17 standing valve cover 18 standing valve joint 19 jointings.
Detailed description of the invention
Horizontal well Special oil pump, including pump barrel 4, assembly for plunger 5 and standing valve assembly 6, described assembly for plunger 5 includes post
Plug joint 7, plunger 10, valve ball valve seat and plunger inner tube 11, valve ball valve seat uses taper ball 8 and conical seat 9, taper ball 8 and cone
Shape seat 9 cooperating, plunger 10 is enclosed within plunger inner tube 11；Pump barrel 4 upper end connects centering ring 2, and pump barrel 4 upper end is unsettled, pump barrel
4 lower ends connect standing valve assembly 6, and standing valve assembly 6 external wall of upper portion connects jointing 19, and jointing 19 upper inside wall connects
Load outer tube 3, load outer tube 3 upper end outer wall connects outer tube top connection 1.
Described standing valve assembly 6 includes reducer union 13, righting rod 14, spring 15, wiper block 16, standing valve cover 17 and consolidates
Determining valve union 18, reducer union 13 top inside and outside wall connects pump barrel 4 and jointing respectively, and reducer union 13 lower end connects fixing
Valve bonnet 17, standing valve cover 17 lower end connects standing valve joint 18, and standing valve cover 17 top and reducer union 13 bottom are respectively provided with
Wiper block 16, righting rod 14, through two wiper blocks 16, is cased with spring 15 outside righting rod 14, spring 15 is positioned at two wiper blocks 16
Between；Standing valve cover 17, spring 15, righting rod 14 and wiper block 16 play the effect of righting, and centering is good, solves in level
In well during oil pumping, valve ball closes the delayed and problem that partially falls, thus improves life-span and the pump efficiency of oil well pump.
The invention have the advantage that 1, pump barrel 4 inside and outside differential pressure is zero, and pump barrel 4 will no longer forced expansion deformation.Decrease leakage
Amount, improves pump efficiency.
2, decrease other parts because of stress deformation, cause the probability that whole pump lost efficacy.
3, simple in construction, operation technique does not increase new workload.
4, be applicable to inclined shaft and horizontal well, improve pump efficiency and the life-span of oil well pump.
5, oil pumping pumps into well depth and will be greatly improved, it is adaptable to the exploitation of ultradeep well.It may be said that the reform of this structure,
Would is that a revolutionary breakthrough.The exploitation making ultradeep well becomes a kind of possible.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit；To the greatest extent
The present invention has been described in detail by pipe with reference to preferred embodiment, and those of ordinary skill in the field are it is understood that still
