Be further optimization and/or improvements below to above-mentioned technical solutions of the utility model:
The pairing outside of above-mentioned notes steam vent can have the vapour of notes to lead cover, and this notes vapour is led cover and can be installed on the whole pump barrel.
The top of above-mentioned whole pump barrel can be equipped with box cupling.
The pairing outside of above-mentioned notes steam vent can have the vapour of notes to lead cover, and this notes vapour is led cover and can be installed on the box cupling.
In the bottom of above-mentioned whole pump barrel box cupling down can be installed.
Above-mentioned upper travelling valve or/and lower travelling valve or/and the valve bonnet of standing valve assembly can be the guiding type valve bonnet that valve ball is had leading role.
The utility model reasonable and compact in structure, characteristic with high pump efficiency, sand control is utilized this multi-functional long-plunger oil well pump can realize annotating to adopt dual-purpose, is specially adapted to thickened oil recovery, the notes that can be used for oblique straight well are adopted dual-purpose oil well pump, but also steam injection of adaptation level well and the requirement of pumping and developing.
Four, description of drawings:
Accompanying drawing 1 is for the master of the utility model most preferred embodiment looks the sectional structure schematic representation,
Coding in the accompanying drawing is respectively: 1 for last box cupling, and 2 lead cover for annotating vapour, and 3 for annotating steam vents, and 4 be that whole pump barrel, 5 is the long-plunger assembly, and 6 be the standing valve assembly, 7 be under box cupling.
Five, embodiment:
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this multi-functional long-plunger oil well pump comprises whole pump barrel 4 and long-plunger assembly 5, standing valve assembly 6 is installed in the bottom of whole pump barrel 4, long-plunger assembly 5 comprises upper travelling valve and lower travelling valve, the steam vent 3 of notes is arranged on the barrel of the top of whole pump barrel 4, long-plunger assembly 5 is positioned at whole pump barrel 4, the top of long-plunger assembly 5 is positioned on the top of integral pump tube 4 in the oil recovery stroke procedure, and the position of annotating steam vent 3 is put at long-plunger assembly 5 and annotated to whole pump barrel 4 bottoms on the barrel of whole pump barrel 4 that steam vent 3 is opening state.Like this, in the oil pumping stroke procedure, make long-plunger assembly 5 in whole pump barrel 4, be in effective sealing state all the time, thereby improved pump efficiency; Simultaneously,, therefore reduced the gravel that enters pump barrel and plunger gap, played the sand control effect because the top of long-plunger assembly 5 is positioned on the top of whole pump barrel 4 all the time.
Can according to actual needs above-mentioned multi-functional long-plunger oil well pump be made further optimization and/or improvements:
In order further to improve performance of the present utility model, as shown in Figure 1, annotating the steam vent 3 pairing outsides has the vapour of notes to lead cover 2, this notes vapour is led cover 2 and is installed on the whole pump barrel 4, on the top of whole pump barrel 4 box cupling 1 is installed, this notes vapour is led cover 2 and preferably is installed on the box cupling 1, has so just alleviated the injury to sleeve pipe; Box cupling 7 down is installed in the bottom of whole pump barrel 4; (that is: the valve bonnet of upper travelling valve is for there being the guiding type valve of leading role to valve ball or/and lower travelling valve is or/and the valve bonnet of standing valve assembly is for the guiding type valve bonnet that valve ball had leading role for upper travelling valve; Perhaps, the valve bonnet of lower travelling valve is for there being the guiding type valve bonnet of leading role to valve ball; Perhaps, the valve bonnet of standing valve assembly is for there being the guiding type valve bonnet of leading role to valve ball; Perhaps, the valve bonnet of upper travelling valve and lower travelling valve is for there being the guiding type valve bonnet of leading role to valve ball; Perhaps, lower travelling valve is or/and the valve bonnet of standing valve assembly is the guiding type valve bonnet that valve ball is had leading role; Perhaps, the valve bonnet of upper travelling valve and standing valve assembly is for there being the guiding type valve bonnet of leading role to valve ball; Perhaps, the valve bonnet of upper travelling valve, lower travelling valve and standing valve assembly is for there being the guiding type valve bonnet of leading role to valve ball), can adapt to the steam injection of oblique straight well or horizontal well and the requirement of oil pumping exploitation like this.
In the utility model: the upper travelling valve of long-plunger assembly and lower travelling valve, standing valve assembly, guiding type valve bonnet all adopt the technology in the prior art oil well pump.
Above technical characteristics has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristics according to actual needs, satisfies the demand of different situations.
Working procedure of the present utility model is as follows: when oil pumping is produced, long-plunger assembly 5 can play seal action all the time to annotating steam vent 3 in the oil pumping stroke procedure, reduce pump leakage like this and improved the efficient of pump, and the top of long-plunger assembly 5 is positioned on the top of whole pump barrel 4 all the time, reduce the gravel that enters pump barrel and plunger gap like this, played the sand control effect.When annotating vapour production, long-plunger assembly 5 is put to whole pump barrel 4 bottoms, the notes steam vent 3 at this moment whole pump barrel 4 tops is opening state, and steam injects the oil jacket annular space by the guiding that notes steam vent 3 is led cover 2 by notes vapour, has alleviated the injury to sleeve pipe.
