Description
Technical field
The utility model is the corollary equipment of oilfield offshore oil well operation under pressure, is a kind of oil well no killing well Operating Pressure
Fluid power output device.
Background technique
The pressure of offshore oilfield is high, is easy to happen blowout, and in order to protect oil reservoir and use manpower and material resources sparingly, offshore oilfield is all adopted
With no killing well workover treatment with pressure.Just it is furnished with marine no killing well workover treatment equipment with pressure using no killing well workover treatment with pressure,
There are the hydraulics such as hydraulic blow out preventer, hydraulic pressure pipe slips, hydraulic lifting frame, hydraulic pressure gate in no killing well workover treatment equipment with pressure
Device, needing to provide satisfactory pressure power source to these hydraulic devices can just make them work, at present these hydraulics
The power source of device is to be driven by a motor hydraulic pump works to provide hydraulic power for it, and motor, which is connected on existing oilfield electric net, is
It is powered, and since the voltage of oilfield electric net is limited, does not drive heavy-duty motor, makes power and the sea of motor-driven hydraulic pump
Power required for upper no killing well workover treatment equipment with pressure is not inconsistent, and sea is not achieved in discharge capacity, the pressure of motor-driven hydraulic pump
The requirement of upper Operating Pressure equipment seriously affects the work of marine Operating Pressure equipment, makes the pressure rating of marine Operating Pressure
The grade and efficiency of needs are not achieved with working efficiency.
Summary of the invention
The purpose of this utility model be in view of the above technology present in deficiency, design a kind of oil well no killing well Operating Pressure
Fluid power output device meets the fluid power requirement of marine no killing well workover treatment equipment with pressure.
Purpose of the utility model is realized as follows: include motor, hydraulic oil container, gear pump, ball-and-seat, overflow valve,
Left hydraulic oil efferent duct, three valves, hydraulic oil input pipe, right hydraulic oil efferent duct, decompression overflow valve, accumulator, motor it is defeated
The input axis connection of shaft and gear pump, motor, gear pump are mounted on the case lid of hydraulic oil container, the suction line insertion of gear pump
In fuel tank, gear pump is connected by the import of hydraulic tube and ball-and-seat, the outlet of ball-and-seat by hydraulic tube and accumulator into
The outlet of mouth connection, accumulator is connect with the inlet side of decompression overflow valve, and the outlet side for depressurizing overflow valve passes through hydraulic oil and inputs
Guan Yusan joins valve connection, and two delivery outlets of three valves are separately connected left hydraulic oil efferent duct, right hydraulic oil efferent duct, overflow valve
It is connected in parallel on the outlet end with ball-and-seat.
Gear pump is driven the beneficial effects of the utility model are: allowing to be used as power using motor using reasonable structure
Hydraulic power supply is provided to marine no killing well workover treatment with pressure, makes the various hydraulic presses in marine no killing well workover treatment with pressure
There is enough power, therefore, the utility model overcomes the deficiencies in the prior art, is able to satisfy marine no killing well workover treatment with pressure
Fluid power requirement, can guarantee the requirement of offshore oilfield snubbing serving with pressure, improve the development effectiveness of offshore oilfield, have
There is significant economic benefit.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model embodiment.
Specific embodiment
1 pair of the utility model embodiment is illustrated with reference to the accompanying drawing.
As shown in Figure 1, the embodiments of the present invention include motor 1, hydraulic oil container 2, gear pump 3, ball-and-seat 4, overflow
Valve 5, left hydraulic oil efferent duct 6, three valves 7, hydraulic oil input pipe 8, right hydraulic oil efferent duct 9, decompression overflow valve 10, accumulator
11, the output shaft of motor 1 and the input axis connection of gear pump 3, motor 1, gear pump 3 are mounted on the case lid of hydraulic oil container 2, tooth
In the suction line insertion fuel tank 2 of wheel pump 3, gear pump 3 is connect by hydraulic tube with the import of ball-and-seat 4, and the outlet of ball-and-seat 4 is logical
It crosses hydraulic tube to connect with the import of accumulator 11, the outlet of accumulator 11 is connect with the inlet side of decompression overflow valve 10, and decompression is overflow
The outlet side of stream valve 10 is connect by hydraulic oil input pipe 8 with three valves 7, and two delivery outlets of three valves 7 are separately connected left liquid
Pressure oil efferent duct 6, right hydraulic oil efferent duct 9, overflow valve 5 are connected in parallel on the outlet end with ball-and-seat 4.
The utility model is integrated in a cabinet, can random handling, it is easy to use.
Gear pump 3 will be exported after 11 steady pressure of accumulator by left hydraulic oil after the hydraulic oil pressurization in hydraulic oil container 2
Pipe 6, right hydraulic oil efferent duct 9 are injected into hydraulic device, and hydraulic device is made to work, and it is with pressure not to complete marine high pressure oil wells
Kill-job workover treatment, low pressure oil liquid after work is reflowable in hydraulic oil container 2, and therefore, the hydraulic oil of the utility model can seal
Closed loop uses.
The utility model is mounted with various matched pressure gauges in each controlling position, for observing pressure and monitoring work
State.
The effect of ball-and-seat 4 is only hydraulic oil to be allowed to flow out from gear pump 3, and hydraulic oil is not allowed to flow back to gear pump 3.Overflow
The pressure that the effect of valve 5 is to maintain oil piping system is constant, prevents system overload, plays safe effect.Three valves 7 are by three
Single valve is connected together, can always be shared into, oil return line, each single valve it is independently operable, be mainly used for on-off hydraulic circuit or change
The flow direction of hydraulic oil.Decompression overflow valve 10 is the pressure of certain primary Ioops in reduction system, within the system hydraulic oil
It is adjusted by decompression overflow valve 10 and maintains constant hydraulic oil output.The effect of accumulator 11 is storage energy, eliminates pulsation
And impact.
