The utility model has the characteristics of the inside and outside pressure of accumulator can keep balance, sealed effectual, the practicality is strong etc.
Description
Technical field
The utility model relates to field of petroleum exploitation, is specifically related to the elasticity of oil well hydraulic-pressure bridge plug delivery toolLeather bag accumulator.
Background technology
In exploitation of oil-gas field process, certain oil reservoir seals well casing with bridging plug after gathering and finishing conventionally,So that in the operation of gathering of new oil reservoir. Adopt the bridging plug delivery tool of electrohydraulic control system need to have oneIndividual larger accumulator, in the course of work, oil pump can be transported to the hydraulic oil in accumulator in oil cylinder.If accumulator seals, along with the minimizing of indoor hydraulic oil, in accumulator, just there will be vacuum, thisThe inlet port of sample oil pump will produce negative pressure, increases the power loss of oil pump; Meanwhile, the dark oil of several kmsThe oil of down-hole and the pressure of water can threaten safely to the self structure of bridging plug delivery tool again.
Utility model content
The utility model has been designed and developed the elasticity leather bag accumulator of oil well hydraulic-pressure bridge plug delivery tool. This realityTo solve in prior art the accumulator of oil well hydraulic-pressure bridge plug delivery tool to subtract at hydraulic oil by novel objectWhen few, when can keeping accumulator structural strength, and make asking of accumulator internal and external pressure balanceTopic. The utlity model has accumulator external and internal pressure and can keep balance, good sealing effect, practicalEtc. feature.
The technical scheme that the utility model provides is:
The elasticity leather bag accumulator of oil well hydraulic-pressure bridge plug delivery tool, comprising:
Accumulator, arranges multiple ventilating groove holes on its sidewall; And
Sealed elastic leather bag, it is arranged on described accumulator inside, described sealing along described accumulator sidewallThe two ends of elasticity leather bag are fixedly connected with airtight end face and the oil outlet end face of described accumulator respectively, described inSealed elastic leather bag is inner is oil storage inner chamber.
Preferably, described sealed elastic leather bag is by tightening the airtight end face seal of rope and described accumulator.
Preferably, described sealed elastic leather bag and described oil-out end face joint are provided with retractable guard.
Preferably, described ventilating groove hole is symmetrical arranged on the sidewall of described accumulator.
Preferably, described ventilating groove hole place arranges airstrainer.
Preferably, described sealed elastic leather bag outer wrap lightweight protecting sheathing.
Preferably, described sealed elastic leather bag and described accumulator fixed connection place are provided with sealing device.
Preferably, described sealed elastic leather bag material is corrosion-resistant fluorubber material.
Preferably, described accumulator is steel matter.
The beneficial effect that the utility model had compared with prior art:
1, accumulator steel cylinder wall is offered ventilating groove hole, can holding structure intensity, have can make down-hole oil,Water flows into, and makes internal and external pressure balance, can not produce negative pressure when oil pump oil suction, and the power that has reduced oil pump damagesLose, also reduce the requirement of sealing structure and the requirement of intensity;
2, in accumulator steel cylinder, be leather bag accumulator, adopt hermetically-sealed construction, avoid the profit of down-hole to infiltrate,Owing to being the accumulator of elasticity leather bag structure, when interior oil quantitative change, can deform, sealed elastic leather bagTherefore inside and outside pressure keep balance, simple and practical, utilizes effective.
Brief description of the drawings
Fig. 1 is structural representation described in the utility model.
Fig. 2 is the sealing of sealed elastic leather bag described in the utility model and oil outlet end face jointPartial enlarged drawing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the artCan implement according to this with reference to description word.
As shown in Figure 1, the utility model provides the elasticity leather bag accumulator of oil well hydraulic-pressure bridge plug delivery tool,Its agent structure comprises: accumulator 100 and sealed elastic leather bag 111; Wherein, the sidewall of accumulator 100Multiple ventilating groove holes 130 are set on 120, and sealed elastic leather bag 111 is along the sidewall 120 of accumulator 100Be arranged on accumulator 100 inside, the two ends of sealed elastic leather bag 111 airtight with accumulator 100 respectivelyEnd face 140 and oil outlet 150 end faces are fixedly connected with, and the inside of sealed elastic leather bag 111 is hydraulic oilStore inner chamber; In the time of interior oil quantitative change, can deform, accumulator 100 is inside and outside by sidewall 120Ventilating groove hole 130 make gas be able to inside and outside circulation, and then make the inside and outside pressure of sealed elastic leather bag 111Therefore keep balance.
In another kind of embodiment, sealed elastic leather bag 111 is high-temperature-resistant and anti-corrosion material; In this enforcementIn example, preferred as one, sealed elastic leather bag 111 is fluorubber material, and it can be fine high temperature resistantAnticorrosive, and this mode is a kind of explanation of preferred embodiments, but is not limited to this, in realityWhile executing the utility model, can select according to user the sealed elastic leather bag 111 of suitable material.
