Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, deepwater drilling sky of the present invention vehicle wave compensating device, comprises passive overhead traveling crane expansion loop (CMC), initiatively heave compensator (AHC).
The overhead traveling crane 9 that floats is placed on the piston rod of the passive compensating cylinder 7 of passive overhead traveling crane expansion loop, the overhead traveling crane 9 that floats is fixedly connected with the piston rod of the Active Compensation oil cylinder of active compensation device 2 above, the cylinder body of Active Compensation oil cylinder 2 and the cylinder body of passive compensating cylinder 7 are fixed on offshore boring island, passive compensating cylinder 7 connects work gas cylinder 8 by gas-liquid accumulator 6, for passive compensating cylinder 7 affords redress power, kept the constant pressure of the piston rod of passive compensating cylinder 7 by oil pressure, realize the compensation of undulation of floating overhead traveling crane 9; Described Active Compensation oil cylinder 2 connects initiatively hydraulic power unit 1 by direction switch valve 3, initiatively hydraulic power unit 1 connects MCC switch board, MCC switch board connection control device module, controller module obtains the signal of offshore boring island heave movement by MRU sensor 5, and the pumping plant startup of initiatively hydraulic power unit 1 is controlled by ECC switch board, and the piston rod that the direction switch valve 3 controlling initiatively hydraulic power unit 1 controls Active Compensation oil cylinder 2 initiatively stretches out and regains, and realizes active compensation.
Two of Active Compensation oil cylinder 2 are connected with governor valve 4 in turn between oil-in, for controlling hydraulicdriven flow between oil cylinder and accumulator and pressure.
The feature of overhead traveling crane wave compensating device has floating overhead traveling crane.Floating overhead traveling crane is contained in a floatable framework, has vertical track, and overhead traveling crane can be moved up and down in orbit by roller.Overhead traveling crane is fixed on the piston rod of overhead traveling crane expansion loop, and when offshore boring island heave movement, relative seabed keeps resting position, and making to be suspended on the drilling equipments such as the drill string of floating overhead traveling crane can carry out drillng operation in seabed.Overhead traveling crane wave compensating device is integrated with passive-type compensation of undulation and active compensation of undulation two class device, jointly realizes compensate function.
Passive compensation is when platform rises, and the overhead traveling crane that floats moves downward along track relative to derrick, the gas in compression master cylinder; When offshore boring island sinks, master cylinder gas expansion pushes away overhead traveling crane and moves upward.Passive-type compensation arrangement is furnished with pipe rupture valve, when the speed of hydraulic cylinder exceedes the operating rate of maximum permission and causes pipe rupture valve two ends pressure reduction excessive, this valve cuts out, thus limit the speed of hydraulic cylinder extension, suddenly to rupture at drill string and under being full of pressure oil condition in accumulator, the safety of the overhead traveling crane wave compensating device that ensures to float.
Active expansion loop is the spare system of the passive expansion loop of day vehicle.When adopting passive compensation of undulation, life period interval between actual rig motion and passive compensation of undulation.Initiatively heave compensator (AHC) applies active force to drill string compensator overhead traveling crane, to reduce skew as far as possible, meets the higher compensation requirement of some moment in drilling process, special object.The active compensation device (AHC) being integrated in passive drill string compensator can make overhead traveling crane more stable relative to seabed position, many drilling conditions is operated and allows to carry out under more severe sea condition.
When offshore boring island is risen by the effect of wave or tide, by the lifting force of drilling rig by the gas compression in accumulator with storage power, now the piston rod of passive oil cylinder moves downward, offset the displacement that platform moves upward, thus ensureing that the operational module position supported does not affect by wave heave movement, relative sea bed keeps resting position substantially; When offshore boring island sinks, accumulator and the gas volume worked in gas cylinder thereof increase, accumulator releases energy, moved upward by hydraulic circuit piston rod, its operational module supported also moves upward, offset the displacement that platform moves downward, thus ensure that the operational module position that it supports does not affect by wave heave movement, relative sea bed keeps resting position substantially.Namely the work capacity of passive-type expansion loop derives from the heave of drilling apparatus, therefore it consumes outside energy hardly.
Work gas cylinder provides pressure to accumulator, by isolating valve, Pneumatic pressure is converted into cylinder efficient pressure by accumulator, drives the piston up-down of oil cylinder, completes passive compensate function.Electric control system controls air control panel and hydraulic system, air control panel controls work gas bottle pressure, and hydraulic system is the oil piping system repairing of passive oil cylinder and accumulator, and controls the multiple-working mode of isolating valve.
When platform rises, overhead traveling crane moves downward along track relative to derrick, the gas of compression work gas cylinder; When platform sinks, work gas cylinder gas expansion pushes away overhead traveling crane and moves upward; When making a trip, provide and control isolating valve locking device and overhead traveling crane is pinned not with making a trip and move up and down; When normally creeping into, by air control panel, control the pressure in work gas cylinder, to keep Bottom Hole Bit Weight In A or to regulate the pressure of the drill.There is travel indicator the position of overhead traveling crane, and the same day, parking stall was when minimum point, and the wire rope that can loosen cylinder makes tourist bus transfer, and continues to creep into; When hook load suddenlys change, passive oil cylinder just supports overhead traveling crane, makes its slowly movement, to ensure safety.Is furnished with speed control valve, when the speed of hydraulic cylinder exceedes the operating rate of maximum permission, this valve cuts out, thus limits the speed of hydraulic cylinder extension, under being full of pressure oil condition in accumulator to ensure to rupture suddenly at drill string, the safety of sky vehicle motion compensator.
By environmental load analysis and platform motion analysis, the heave stroke of passive heave compensator is 4m, and maximum heave compensation speed is 1.22m/s.
Active compensation device (AHC) is arranged on passive overhead traveling crane expansion loop (CMC).Only could open active compensator under passive expansion loop duty, passive expansion loop must first cut out active compensation device before cutting out.
Bucking-out system does not move up and down with the heave of hull by keeping whole drill string, thus keeps the relative constancy of Bottom Hole Bit Weight In A; The compensation rate of passive-type compensation arrangement expansion loop always has a lag time, simultaneously when fluid cylinder plunger motion, inevitably produce a part of frictional force and loss, in order to address these problems, adopt active and passive conbined usage, for overhead traveling crane provides a position stable relative to seabed, reduce the side-play amount of Active Compensation overhead traveling crane as far as possible, platform can both be operated safely under any severe weather conditions.The synergy of Active Compensation and passive compensation makes overhead traveling crane when whole platform moves up and down relative to seabed, the maximum heave displacement of overhead traveling crane can control within tolerance zone, to meet in drilling process part stage operating mode for the high requirement of heave compensation function.
Under usual operating mode, active compensator is not opened, and just bears heave compensation function by passive-type expansion loop.Active compensation device just can be started working after passive heave compensator starts.Initiatively heave compensator work is just started mainly for following action:
(1) land in the module seabed more than 1 ton
(2) land in BOP (band marine riser) module seabed.
(3) settling position operating mode in bore operation (comprise sliding sleeve operation, production tree location setting, reaming, concrete admittedly manage)
(4) actuating cylinder stroke is corresponding with passive system " peak is to peak " stroke.
Based on mathematical simulation and the information of various passive overhead traveling crane compensator system, when actuating cylinder partial pressure is 150bar, the scope of required typical maximum thrust/pulling force will between ± 15mtonnes.
This expansion loop compensates motion towards vertical direction drilling well " hook " motion, when using active compensation device, when being in " active compensation device mode position ", can eliminate the heave movement of 90%.AHC system can apply required active force with the unknown losses in overcome friction and DSC system, for compensating the drill ship heave movement (the drill ship heave movement within 85% is born by passive heave compensator) in 85-90% intervals.
Initiatively AHC is the spare system of passive DSC system, when only adopting passive heave compensation, and life period interval between actual rig motion and passive heave compensation, thus cause the fluctuation of balancing force.Therefore need to start active compensation device (AHC) and active force is applied to drill string compensator overhead traveling crane, with fluctuation range as far as possible, generally get that Active Compensation power is passive balancing force 5%.
Two systems can interact, and when enabling active compensation device (AHC), passive overhead traveling crane expansion loop (DSC) system will start following function:
Start the electromagnetic valve of " decompression " valve in DSC system, passive system is reduced pressure.Namely when adopt active compensation device (AHC) for land operation time, Signal transmissions is to DSC system to discharge partial-compensation pressure in this system, and during to ensure to open AHC, total support force is stablized, and opens AHC simultaneously and drives the motion of drill string downward speed stabilizing.
For AHC system provides the signal in the pressure sensor of DSC oil cylinder working-pressure.In use, Active Compensation cylinder block is fixed on offshore boring island, and its piston rod is connected with floating overhead traveling crane.Controller module obtains the coherent signal of offshore boring island heave movement from MRU sensor, comprise heave displacement, speed etc., and started by the pumping plant of ECC switch board, MCC switch board hydraulic control system after being resolved by control algolithm, form oil pressure, and the direction switch valve of hydraulic control system, control the A mouth of Active Compensation oil cylinder, the oil-feed in turn of B mouth, drive the piston rod of Active Compensation oil cylinder initiatively stretch out and regain, realize active compensation function; Pass through, the signal feedback such as displacement, speed, balancing force of active compensation is to controller module, the Platform movement information progress that continuous and MRU provides contrasts, resolves, adjust the control signal to pumping plant and valve group, finally realize the closed-loop control of actuating cylinder heave compensation ability and MRU Platform movement information; Control panel has the controlling functions such as automatic, manual, and can show the various information of compensation in real time.
By keeping whole drill string not move up and down with the heave of hull, thus keep the relative constancy of Bottom Hole Bit Weight In A; The compensation rate of passive-type compensation arrangement expansion loop always has a lag time, simultaneously when fluid cylinder plunger motion, inevitably produce a part of frictional force and loss, in order to address these problems, adopt active and passive conbined usage, for overhead traveling crane provides a position stable relative to seabed, reduce the side-play amount of Active Compensation overhead traveling crane as far as possible, make drillng operation can safety operation under severe weather conditions.
Passive compensating cylinder body is fixed on offshore boring island, and when offshore boring island moves upward, cylinder body moves upward with identical speed.The cavity of resorption of its piston rod is connected with large capacity high pressure gas, relative to being connected on air spring, now, piston rod moves downward, because the friction effects of the rigidity of air spring itself and piston and cylinder body, the speed that piston rod moves down is subject to hindering impact, to a certain extent lower than Platform movement speed.Now, Active Compensation power is supplied to piston rod external force, along piston rod movement direction, for overcoming the impact of the stiffness effect of air spring own and frictional force, improving passive compensating piston bar movement velocity, reaching the requirement of compensation effect.Like this, active and passive hybrid compensation mechanism just makes the gap of heave compensation speed and Platform movement speed very little, solve passive compensator compensates speed sluggishness and the problem of Platform movement speed, drilling condition can be met and comprise the working condition requirement installing the degree of precision such as BOP, production tree, inclined shaft measurement.When platform moves downward, the mechanism of main passive hybrid compensation is also similar.
The effect of main passive hybrid compensation is also embodied in the constant of balancing force simultaneously.Because have system friction, the factor impact such as pressure change that cylinder gas volumetric change causes, the balancing force fluctuation range of single passive oil cylinder expansion loop is 10% to 15%, and can not meet current drilling condition requirement balancing force fluctuation range can not requirement more than 10%.Therefore, the balancing force of passive expansion loop oil cylinder should be designed to 5% of specified compensating load, makes up passive expansion loop undulate quantity has more 5% impact than working condition requirement.Active Compensation power is 5% of nominal load 454, i.e. desirable 25t.Like this, the synergy of just assurable Active Compensation and passive compensation makes overhead traveling crane when whole platform has upper and lower 4m mobile relative to seabed, and the maximum displacement of overhead traveling crane controls within 0.5m, ensure that the relative constancy of Bottom Hole Bit Weight In A, meets drilling condition requirement.
Floating overhead traveling crane is final by compensating unit, is connected with drill string, tourist bus; Passive compensating cylinder affords redress power, is kept the constant pressure of piston rod, realize the compensation of undulation of overhead traveling crane by oil pressure; Accumulator is gas-liquid accumulator, is that liquid carrying supplies pressure, thus keeps the constant of oil pressure by air pressure; Governor valve: control the hydraulicdriven flow between oil cylinder and accumulator and pressure, play emergency braking function in emergency; Work gas cylinder provides constant air pressure for accumulator; Bailout bottle is that work gas cylinder compensates pressure; MRU simulator obtains platform operation information, by electric control system controls initiatively hydraulic power unit, controls Active Compensation oil cylinder and moves up and down, and form closed loop Bit andits control by displacement detecting.
