Description
Technical field
The present invention relates to a kind of oil field shaft mouth apparatus for work, particularly hydraulic-driven apparatus for work.
Background technology
Preventer remote control is the visual plant for controlling wellhead blowout preventor, also known as remote console, its
Preventer is connected by high-pressure oil pipe, control preventer is applied by the hydraulic oil in its high-pressure oil pipe；Preventer is remote
Process control device is by base, fuel tank, pump group, accumulator group, manifold, various valve members, instrument and electric cabinet
Composition, its major function is to produce high voltage control liquid by pump group, and is stored in accumulator group, when need
When wanting open and close preventer, the high voltage control liquid from accumulator group is divided by the 3-position 4-way rotary valve of manifold
It is fitted on each control object --- in preventer；Its pump group is furnished with two sets of independent power sources, i.e. electric oil pump
And hand oil pump, it is standby that accumulator group has enough highly pressurised liquids to store, and meets and closes whole preventer groups and opening
The control requirement of the requirement of hydraulic operated valve, with automatic, the control device for stopping, each prevents electric oil pump
The open and close action of spray apparatus is controlled by corresponding 3-position 4-way rotary valve；The control of preventer remote control
There is standby pressure source interface on manifold, pressure source can be introduced as needed within；High pressure line has hard tube line and soft
Two kinds of pipeline, typically with soft pipeline, the two ends of soft pipeline are the snap joint of self-sealing, realize that preventer is remote
The connection of process control device and preventer；Warning device is installed on preventer remote control, to accumulator
The operating of pressure, bleed pressure, oil tank liquid level and electric oil pump is monitored, when above-mentioned parameter is beyond setting
Alarm limit when, can on preventer remote control to being spoken, visual alarm, indicate operation
Personnel are taken measures, and it can be transported in the low alarm of energy storage pressure, the low alarm of oil tank liquid level and electric oil pump
Turn abnormal alarm；Electric cabinet is fixed on preventer remote control, is pacified in the electric line of electric cabinet
The motor of load blowout preventer remote control, motor connection oil pump, when the electro-motor is turning, band
Dynamic oil pump is rotated, and by entering oil pipe, by the oil suction in fuel tank, and is forced through flowline and is transported to accumulation of energy
In device group, enter oil pipe one end and be fastened on fuel tank, the other end is fastened on oil pump oil inlet, fuel-displaced
Pipe one end is fixedly connected on the oil-out of oil pump, other end connection check valve inlet, one-way valved outlet connection oil
Pipe one end, it connects oil pipe other end connection accumulator group, and so when oil pump is rotated, pressure oil is through check valve
To accumulator group fuel feeding；Connection pressure controller is installed, when system pressure reaches certain setting value on electric cabinet
When, pressure controller automatically cuts off power supply, makes electric oil pump fuel cut-off, when system pressure is depressured certain value
When, electric oil pump can reset automatically work, so make accumulator group pressure remain at it is certain
In the range of, be available at any time operation preventer be turned on and off, accumulator group by oil pipe connect installation isolating valve,
Overflow valve, reconnects control manifold, and its manifold connects the oil inlet of 3-position 4-way rotary valve, as long as so pulling
Corresponding 3-position 4-way rotary valve handle, makes to be capable of achieving "ON", the operation of "Off" preventer, so, storage
There is the pressure oil in accumulator group by accumulator isolation valve, oil filter, again by decompression overflow valve decompression
Afterwards, it is used on preventer remote control to each 3-position 4-way rotary valve oil inlet into control manifold
3-position 4-way rotary valve --- liquid rotary valve is " 0 " type function, rotate valve handle " in " position when, each chamber
It is not communicated with, and when handle is in "ON" position formula "Off" position, as pressure oil enters oil cylinder in preventer
One end, the fluid of the other end makes through 3-position 4-way rotary valve oil return box；Accumulator group is generally multiple bellows and stores
The structure that energy device interconnects, its bladder type hydropneumatic accumulator plays storage energy in hydraulic system, stabilization
Pressure, reduces power consumption, and compensation leakage is oozed, various effects such as absorption pressure pulsating force and mitigation impulsive force,
It supports that on the bracket of preventer remote control it is by shell, capsule and charge valve and hydraulic fluid port securely
Composition, there is charge valve on shell top, there is hydraulic fluid port the capsule in charge valve connection shell cavity, shell lower end, and hydraulic fluid port is passed through
In logical shell, nitrogen is filled with its capsule, composition accumulator group is combined in several bladder type hydropneumatic accumulator connections,
Its intracapsular nitrogen has certain pressure, when hydraulic oil is entered in shell by hydraulic fluid port, compresses capsule, makes glue
The air pressure of intracapsular nitrogen rises, and the pressure of its hydraulic oil rises to certain amplitude, conversely using accumulator
When, due to the hydraulic oil in the High Voltage compressing shell in capsule, make oil with necessarily having pressure, can be by oil
Mouthful outwardly against pressure oil being transported into certain position by oil pipe, and electric oil pump is started working, and is made
Its pressure oil remains certain pressure, so as to control preventer.Preventer is a kind of because taking precautions against blowout thing
So design, after well kick generation can safe closing well in time device.In Downhole Construction, hydraulic pressure
The effect of tap is fixed part and rotating part in suspention down-hole string, connection circulation flushing pipeline, and
Can carry out turning the construction operations such as down-hole string completion well-flushing, sand surfing, unfreezing circulation.In Downhole Construction,
Particularly carrying out turning the construction operations, hydraulic pressure tap such as down-hole string completion well-flushing, sand surfing, unfreezing circulation
Used as major impetus device, preventer will simultaneously be equipped in downhole operation equipment as main jet-preventing tool
On.Hydraulic pressure tap is driven by tap Remote Hydraulic drive device, and preventer is then by preventer control
Device implements control.Blowout preventing control apparatus and tap Remote Hydraulic drive device be do not have mutually it is related
Respective two independent covering devices, blowout preventing control apparatus can not drive hydraulic pressure tap, the long-range liquid of tap
Hydraulic driver can not control preventer.The downhole operation equipment of equipment hydraulic pressure tap and preventer just must
Must be equipped with and blowout preventing control apparatus and tap Remote Hydraulic drive device are installed.So, preventer control dress
Put does not have centralized and unified into a device with tap Remote Hydraulic drive device, and two device is provided separately,
Seem dispersion, it has not been convenient to transports, install and operates, and manufactures height.
The content of the invention
It is an object of the invention to provide a kind of hydraulic-driven apparatus for work；Hydraulic-driven apparatus for work includes blowout prevention
Device remote control and tap Remote Hydraulic drive mechanism and actuating unit and tap；It is blowout prevention
Device remote control and tap Remote Hydraulic drive mechanism mutually organic abundant combination, the one of unified formation
Individual overall apparatus.On the one hand hydraulic-driven apparatus for work realizes blowout prevention function by preventer remote control,
