Abstract
The utility model discloses an electric submersible pump production string suitable for manual lifting. The electric submersible pump production string comprises an oil pipe sleeved in a sleeve, a Y joint arranged on the oil pipe, an electric submersible pump connected with the Y joint, and a pipe or a sliding sleeve with holes, a positioning seal, an inserting seal, a production sliding sleeve and a sand control packer which are sequentially arranged on the Y joint from top to bottom, wherein an underground safety valve is arranged between the upper part of the electric submersible pump and the Y joint and is connected with a ground hydraulic control station through a hydraulic control pipeline, and the ground hydraulic control station provides pressure control. According to the electric submersible pump production string, the underground safety valve is arranged on the upper part of the electric submersible pump and the ground hydraulic control station provides pressure control on the underground safety valve through the hydraulic control pipeline; because a cable packer is eliminated, the tonnage for lifting the string is greatly reduced; moreover, during well washing and well killing, liquid is discharged smoothly and the efficiency of washing and killing a well is improved.
Description
Technical field
The utility model relates to the flow string in oil exploitation, relates in particular to a kind of electric submersible pump producing tubular column that can ensure the applicable artificial lift under oil well well control safety condition.
Background technology
As shown in Figure 1, existing flow string comprises: be sleeved on oil pipe, the liquid controling pipe line 1 being connected with ground control system in sleeve pipe, be arranged on hydraulic control storm valve 2 on oil pipe, pass through the cable-passing packer 3 of liquid controling pipe line 1, with screwed connection at the Y-shaped connector 4 on oil pipe, the electric submersible pump 5 being connected with Y-shaped connector 4, be arranged on successively with holes pipe or sliding sleeve 6, the location sealing 7 of Y-shaped connector below 4 from top to bottom, insert sealing 8, produce sliding sleeve 9, sand control packer 10, by the above-mentioned flow string that connects and composes an oil exploitation.
In order to meet the requirement of country to oil gas well control, at present, in electric submersible pump producing tubular column, all need to be provided with cable-passing packer and storm valve, the vent valve of cable packer and storm valve are all by liquid controling pipe line, by ground hydraulic-control station, are controlled; In needs, cable packer and storm valve seal respectively the gas stream passage of oil jacket annular space and oil pipe inner chamber, to realize safety closing well.Existence due to cable-passing packer, the power cable of electric submersible pump need to pass through cable-passing packer, like this, not only to construction, bring workload, and cable, when passing through cable-passing packer, need to be done special cable penetration construction, easily cause the weak spot of cable, for cable fault hides the foreshadowing; In addition, when pump detection and workover, upper lifting pipe post needs first deblocking cable-passing packer, so, will certainly cause the increasing of carrying tonnage; Meanwhile, washing, during kill-job, due to the existence of cable-passing packer, this place's well-flushing runner is again narrow vent valve pore, can make to wash, kill rate is limited, and impact is washed, kill-job efficiency.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of electric submersible pump producing tubular column of applicable artificial lift, it is arranged on storm valve between electric submersible pump and Y-shaped connector, and makes storm valve by ground hydraulic-control station, provide pressure to control by liquid controling pipe line; Meanwhile, owing to having removed cable-passing packer, the tonnage weight while not only greatly reducing upper lifting pipe post, and, washing, during kill-job, also make liquid displacement unobstructed, improved wash, the efficiency of kill-job.
The purpose of this utility model is realized by following technical scheme:
A kind of electric submersible pump producing tubular column of applicable artificial lift, comprise: be sleeved in sleeve pipe oil pipe, be arranged on the Y-shaped connector on oil pipe, the electric submersible pump being connected with Y-shaped connector, be arranged on successively pipe with holes or sliding sleeve, location sealing, insertion sealing on Y-shaped connector from top to bottom, produce sliding sleeve, sand control packer, it is characterized in that: between the top of electric submersible pump and Y-shaped connector, a storm valve is installed, this storm valve is connected with ground hydraulic-control station by liquid controling pipe line, by ground hydraulic-control station, provides pressure to control.
Described storm valve is: hydraulic control storm valve.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and it is arranged on storm valve on the top of electric submersible pump, and makes storm valve provide pressure to control by liquid controling pipe line by ground hydraulic-control station; Owing to having removed cable packer, the tonnage weight while not only greatly reducing upper lifting pipe post, and, washing, during kill-job, also make liquid displacement unobstructed, improved wash, the efficiency of kill-job.

Major label description in figure:
Liquid controling pipe line, 2. storm valve, 3. cable-passing packer, 4.Y joint, 5. electric submersible pump, 6. pipe with holes or sliding sleeve, 7. location sealing, 8. insert sealing, 9. produce sliding sleeve, 10. sand control packer, 11. storm valves, 12. liquid controling pipe lines.
The specific embodiment
As shown in Figure 2, the utility model comprises: be sleeved in sleeve pipe oil pipe, be arranged on the Y-shaped connector 4 on oil pipe, the electric submersible pump 5 being connected with Y-shaped connector 4, be arranged on successively pipe with holes or sliding sleeve 6, location sealing 7 on Y-shaped connector 4 from top to bottom, insert sealing 8, produce sliding sleeve 9, sand control packer 10, wherein, between the top of electric submersible pump 5 and Y-shaped connector 4, a storm valve 11 is installed, this storm valve 11 is hydraulic control storm valve, the storm valve 11 of hydraulic control is connected with ground hydraulic-control station by liquid controling pipe line 12, by ground hydraulic-control station, provides pressure to control.
Because electric submersible pump 5 of the present utility model is to provide electric power by ground, and to the motor of electric submersible pump 5, provide power by power cable, the rotation of driven by motor impeller of electrical pump, lifts ground underground oil-water, thereby, realize the object of artificial lift.And when hydraulically controlled station voltage supply, the storm valve 11 of hydraulic control is opened; During hydraulically controlled station pressure release, the storm valve 11 of hydraulic control is closed.Thereby realization is closed formation fluid and is flowed to the fluid passage in oil jacket annular space and oil pipe.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
