When the present invention pulls out of hole, engine (11)-hydraulic oil pump (12) is organized continuously to hydraulic accumulating device pump oil, use when storing hydraulic oil (energy) supply and demand and will promote tubing string (7) by hydraulic accumulating device, 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 shelves " of lifting force less than tubing string (7) gravity, hydraulic oil in lifting hydraulic jack group (2) high pressure chest is pushed back in the hydraulic accumulating device by descending tubing string (7) store (that is to say that hydraulic accumulating device has absorbed the potential energy that discharges when tubing string (7) is descending), wait drill down operator usefulness for making 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.
The present invention is with lifting hydraulic jack group (2) lifting or transfer tubing string (7) directly or behind increment, thereby no longer needs derrick, winch, travelling block etc.
The present invention not only can make trepan or other machine that workover rig can also be made hydraulic energy-accumulating.
Other purposes of the present invention and advantage can be cheer and bright by reading the embodiment that describes in detail below in conjunction with accompanying drawing, wherein:
Fig. 1: hydraulic energy accumulation petroleum workover rig lateral view of the present invention.
Fig. 2: hydraulic energy accumulation petroleum workover rig vertical view of the present invention.
Fig. 3: the hydraulic system principle figure of hydraulic energy accumulation petroleum workover rig of the present invention or trepan.
With reference to accompanying drawing 1-3, one cover lifting hydraulic jack group (2) is housed on its middle machine body (1), piston rod (3) top of lifting hydraulic jack group (2) is bound up on the frame that moves about (4), behind stroke process increment assembly pulley (5) increment of lifting hydraulic jack group (2), promote or transfer tubing string (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 housed on the fuselage (1), be equipped with on the frame that moves about (4) and guide roller (10) that lead (9) matches.
The present invention has a Hydraulic Station, is made up of engine (11), hydraulic oil pump (12), 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 hydraulic oil of all oil sump tanks (13) must flow to top petrol tank (14) earlier, has only after top petrol tank (14) is full of, and its overflow just can be flowed back to fuel tank (13), and is empty to guarantee that each chamber of lifting hydraulic jack group (2) can be full of unlikely suction all the time.
Hydraulic accumulating device of the present invention is by holding fluid cylinder (17) and being formed and be provided with aerating device (20) by the coupled pressure gas bag (19) of tracheae line (18).
Lifting hydraulic jack group of the present invention (2) also can be made up of two, three or more hydraulic jack.
The present invention also has a cover detection, maneuver control device, is made up of content gauge (21), pressure gauge (22), manual pilot valve group (23), hydraulic valve bank (24), choke valve group (brake valve group) (25) and drain valve (26) etc.
Above-mentioned Hydraulic Station, fuselage (1), hydraulic accumulating device detect maneuver control device and all are installed on the vehicle (27), and fuselage (1) is controlled it by amplitude oil cylinder (28) and hoisted or put upside down.For make on the fuselage (1) lifting hydraulic jack group (2) all the time and oil pipeline (15) be communicated with, be equiped with high-pressure hose (16).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.
Diverse location by manual pilot valve group (23) handgrip, the switching situation of each valve in the decision hydraulic valve bank (24), thereby each epicoele of each cylinder in the lifting hydraulic jack group (2) and the path of each cavity of resorption have been determined, become high pressure chest with the chamber of holding the hydraulic oil connection that stores in the fluid cylinder (17) this moment, and the chamber that all the other and top petrol tank (14) (being the normal pressure part) are communicated with becomes low pressure chamber.
If having only epicoele is being directed downwards of high pressure chest then pressure, lifting force is negative shelves, and upwarding pressure if all cavity of resorptions all become high pressure chest is maximum, becomes the positive shelves of lifting force maximum.If becoming high pressure chest simultaneously, the cavity of resorption that the epicoele that has has makes a concerted effort because of different combinations can form different liftings.So under the substantially constant situation of system pressure, as long as design different epicoele sectional areas and cavity of resorption sectional area dexterously and use the various connection combination of the upper and lower chamber of each cylinder and just can form a series of " power shelves ", comprise negative lifting " power shelves ", " zero span " and several positive liftings " power shelves ", satisfy the workover rig requirement of the various lifting force of needs at any time.Under when boring, select suitable " the power shelves " of lifting force less than tubing string (7) gravity, descending tubing string (7) just can be pressed into the interior hydraulic oil of each high pressure chest in each lifting hydraulic jack group (2) at that time to hold in the fluid cylinder (17) and go this moment, make and hold the increase of fluid cylinder (17) mesohigh oil reserve, reach the accumulation of energy purpose.When needs are mentioned single pipe or tubing string (7), as long as it is just much of that to spend a part of holding newly-increased high pressure oil storage in the fluid cylinder (17).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 tubing string (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, tubing string (7) is pressed into the hydraulic oil that holds fluid cylinder (17) will be above the capacity that holds fluid cylinder (17) under the tubing string (7).Can also utilize this part unnecessary energy this moment.
Each lifting force of " power shelves " has level, can't guarantee to hoist or the stepless variation in ground of adjusting to changed conditions of the speed transferred and acceleration, and institute thinks the various needs that satisfy operating personnel, installs choke valve group (brake valve group) (25) in oil pipeline (15).Choke valve group (25) can infinitely be regulated, and has remedied the shortcoming that " power shelves " have level.Choke valve group (25) also can be checked car on urgent situation incision oil-break road, guarantees safety.
When pulling out of hole beginning, the tubing string (7) in the well is very long, and weight is big, and the high pressure oil storage that every one endowel (7) consumes is many, and along with the carrying out of trip-out operation, tubing string (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 tubing string (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 group (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 group (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.
