Abstract
The hydraulic energy storage oil well repairing machine is different from a conventional well repairing machine from appearance to principle. It applies the principle of pneumatic energy storage. When the drilling machine is started, the small-power machine can continuously do work, and the energy storage device can store energy to lift oil pipe, so that the installed power of said invention is 1/4 of conventional workover rig under the condition of that its load and speed are not reduced. When the drill is put down, the power machine is not started, and the energy storage device absorbs the potential energy of the oil pipe for the operation of the drill. Can greatly save energy.
Description
The invention belongs to a kind of petroleum well servicing rig.
At present the petroleum well servicing rig of countries in the world is all similar, the Hoisting System of being made up of derrick, overhead traveling crane, travelling block, hook, winch mostly, the transmission system of dynamic machine, gearbox, transmission device composition
To trip out and be lowered to be the process that repeats again and again for instrument and oil pipe in the well workover process.Aboveground in a bite, number is tripped out and is lowered in the oil pipe and the instrument (tens of tons often weigh) of km.See almost there is not work done on the macroscopic view.Yet in fact consume fuel is a lot, because trip out in the process of an oil pipe when pulling out of hole, though the time of pure lifting tubing string only accounts for about 1/4 of whole process, all the other times are auxiliary operations, but when hoisting oil pipe, require in the short time, to make very big merit, require installed power very big, and in overhead time, also to consume a part of fuel though powerful engine is no-load running.Even during following brill, engine can not stall, causes a large amount of wastes of fuel (energy).
The objective of the invention is to provide a kind of energy-conservation workover rig.
Though the energy storage of atmospheric pressure principle that the present invention uses not is new discovery, is applied to the workover rig beyond example.And conventional accumulator is too little, far can not satisfy to be used for the requirement that workover rig will store thousands of kilojoules at least, so also want a kind of special ultra-large type energy storage of atmospheric pressure device.
The present invention is achieved in that the outlet of engine [11]-hydraulic oil pump [12] group and a cover energy storage of atmospheric pressure device are communicated with; Three lifting hydraulic jacks [2] are fixedly mounted on the fuselage abreast, and its piston rod [3] is fixedly mounted on the wheel carrier that moves about [4]; Increment pulley [10] group is connected with the suspension ring that hoist by wire rope [6]; Each chamber of lifting hydraulic jack [2] is communicated with by the outlet of maneuver control device and energy storage equipment or the top petrol tank of normal pressure [14].
When the present invention pulls out of hole, engine [11] one hydraulic oil pumps [12] group is continuously to energy storage of atmospheric pressure device pump oil, use when storing hydraulic oil (energy) supply and demand and will promote oil pipe [7] by energy storage equipment, so the installed power of this machine is under load and the nondecreasing condition of speed, only be about 1/4th of uniform machines, its engine [11] can be diesel engine, motor or other prime mover.Under do not drive engine [11] when boring, select " the power retaining " of lifting force less than oil pipe [7] gravity, hydraulic oil in lifting hydraulic jack [2] high pressure chest is pushed back in the energy storage of atmospheric pressure device by descending oil pipe [7] store (that is to say that the energy storage of atmospheric pressure device has absorbed the potential energy that discharges when oil pipe [7] is descending), for the usefulness such as oil pipe [7] drill down operator of etc.ing that makes up a joint.
So energy conservation significantly just.
The minimizing of installed power makes that again the engine [11] of workover rig can be a motor, directly utilizes the well site power supply, makes operation convenient.
Lifting or following drain line [7] after the present invention uses lifting hydraulic jack [2] by increment pulley [10] group increment, thereby no longer need derrick, winch, travelling block etc., also lifting hydraulic jack [2] directly can be connected with the suspension ring that hoist.
The present invention not only can make workover rig also can be in order to make trepan or other machine of hydraulic energy-accumulating.The present invention can adopt more than three or the lifting hydraulic jack [2] of following number according to different needs, or engine [11] one hydraulic oil pumps [12] group more than is set.

The present invention is described in further detail below in conjunction with accompanying drawing:
Three lifting hydraulic jacks [2] are housed on the fuselage of the present invention [1], piston rod [3] top of lifting hydraulic jack [2] is fixed on the wheel carrier that moves about [4], three piston rods [3] synchronization telescope, behind stroke process increment pulley [5] increment of piston rod [3], directly promoted or following drain line [7] by wire rope [6], wire rope [6] is adjusted degree of tightness with adjusting screw(rod) [8].For setting upright moving up and down of piston rod [3], lead [9] is arranged at fuselage [1] top, and guide roller [10] then is housed on the wheel carrier that moves about [4].
The present invention has a Hydraulic Station, is made up of engine [11], hydraulic oil pump [12], main fuel tank [13], top petrol tank [14] and oil pipeline [15].The oil pipeline of movable part need be used high-pressure hose [16].Top petrol tank [14] can be provided with separately, also can utilize space in the lead [9] as top petrol tank [14].The oil of one switchback main fuel tank [13] must have only after top petrol tank [14] is full of earlier through top petrol tank [14], and its overflow just can be flowed back to main fuel tank [13], and is empty to guarantee that lifting hydraulic jack [2] can be full of unlikely suction all the time.
The present invention has the large-scale energy storage of atmospheric pressure device of a cover, and it is by holding fluid cylinder [17] air hose [18], pressure gas bag [19] and aerating device [20] composition.
The present invention also has a cover detection, maneuver control device, by content gauge [21], pressure gauge [22], manual pilot valve group [23], hydraulic valve bank [24], choke valve (brake valve) [25] and drain valve compositions such as [26].
Above-mentioned all devices all can be installed on the trailer (or truck) [27], and fuselage [1] is controlled and can be fallen or stand up by amplitude oil cylinder [28], so that movement.Fuselage [1] top has drawn guy wire [29] to stablize guaranteeing, fuselage [1] bottom is provided with very heavy [30] and larger area pressing plate [31] with straightening fuselage [1] and enough substrate support areas are provided.
Hydraulic oil pump [12] is got to the hydraulic oil of high pressure to hold in the fluid cylinder [17] by the stop valve of opening [32] and is gone, and by holding fluid cylinder [17], tracheae line [18] and this cover energy storage equipment of high pressure gas bag [19] high-pressure and hydraulic oil is stored.When content gauge [21] indication is held liquid level in the fluid cylinder [17] when too high, can fuel cut-off or open drain valve [26] and discharge a part.
The maneuver control device of being made up of manual pilot valve group [23] and hydraulic valve bank [24] is controlled the path of each upper and lower cavity in each lifting hydraulic jack [2], makes to be respectively high pressure chest or low pressure chamber.Manual which chamber of determining positions of pilot valve group [23] handgrip and hold fluid cylinder [17] (promptly and high-pressure section) connection and become high pressure chest.All the other each chambeies then and top petrol tank (promptly with the normal pressure part) connect and can and become low pressure chamber.
Because the difference of high-low pressure chamber combination, make the associating lifting force of each lifting hydraulic jack [2], under the constant substantially situation of system pressure, can ascendingly be divided into a lot of levels, promptly a lot " power retaining " (" neutrals " of comprising no lifting force).Like this, just can satisfy the workover rig requirement of the various lifting force of needs at any time.Under when boring, select suitable " the power retaining " of lifting force less than oil pipe [7] gravity, this moment descending oil pipe [7] just at that time the interior hydraulic oil of each hoist cylinder [2] high pressure chest be pressed into to hold in the fluid cylinder [17] and go, make and hold the increase of fluid cylinder [17] mesohigh oil reserve, reach the accumulation of energy purpose.When needs were mentioned single oil pipe [7], to hold in the fluid cylinder [17] a newly-increased high pressure oil storage part just much of that as long as spend.So do not need out engine [11] during tripping operation, needn't use hydraulic oil pump [12] fuel feeding.Be exactly under the situation of this not fuel feeding, along with oil pipe [7] is following more dark more, the high pressure oil storage meeting of holding in the fluid cylinder [17] gets more and more.After certain depth, oil pipe [7] is pressed into the hydraulic oil that holds fluid cylinder will be above the capacity that holds fluid cylinder [17] under the oil pipe [7].Can also utilize this part unnecessary energy this moment.
Each lifting force of " power retaining " has level, can't guarantee to hoist or the speed transferred and acceleration can adjust to changed conditions stepless variation, think and in oil pipeline [15], be equiped with choke valve (brake valve) [25] by the various needs that satisfy operating personnel.Choke valve [25] can infinitely be regulated, and has remedied the shortcoming that " power retaining " has level.Choke valve [25] also can be checked car on urgent situation incision oil-break road, guarantees safety.
When pulling out of hole beginning, the oil pipe [7] in the well is very long, and weight is big, and the high pressure oil storage that one every oil pipe [7] consumes is many, and along with the carrying out of trip-out operation, oil pipe [7] is shorter and shorter, and weight is more and more lighter, and the oil storage of consumption high pressure is also fewer and feweri.For rationally utilizing the power of hydraulic oil pump [12] engine [11], one or more hydraulic oil pump [12] engine [11] can be set so that according to circumstances level is made into the output discharge capacity of several different high-pressure and hydraulic oil.
Another advantage of the present invention is: when oil pipe [7] is hampered and workover rig lifting force when not enough, can close stop valve [32], the hydraulic oil that hydraulic oil pump [12] is got directly enters each lifting hydraulic jack [2] by hydraulic valve bank [24], turn the discharge capacity of hydraulic oil pump [12] simultaneously down, the pressure of raising system, (as hydraulic oil pump [12] is constant output pump, and then pressure improves the back discharge capacity and can descend automatically and needn't regulate).The associating lifting force of each lifting hydraulic jack [2] can increase exponentially this moment, and may make the releasing that is hampered.Certainly the hoisting velocity of this moment is extremely low.Just just require when being hampered " pulling out firmly " fortunately to carry on the low speed to guarantee safety.
