Description
Technical field
The utility model relates to the large and small workover treatment equipment of coal bed gas well, i.e. coal bed gas well minitype motivation water tap.
Background technology
In the prior art, workover rig heavy repair task needs rotary drill rod, and traditional work mode adopts machinery or hydraulic swivel head to realize spinfunction, and driven by rotary disc kelly bar rotates, and lower stacks creeps into, and kelly bar top is held by water tap is outstanding.During each stacks, all will first unload kelly bar and water tap, be put in rat hole, connect water tap and kelly bar again after connecting drilling rod, could continue operation, operation is loaded down with trivial details, inefficiency.Power swivel comprises the compositions such as drop handle, gooseneck, packing unit, casing, central tube, joint.Power swivel is suspended on workover rig derrick hook, provides drilling system.If substitute hydraulic swivel head with power swivel, will be significant improvement, and can increase work efficiency.
Utility model content
The purpose of this utility model is the coal bed gas well minitype motivation water tap providing a kind of alternative hydraulic swivel head for above-mentioned deficiency, has stacks convenient, time saving and energy saving, the feature that operating efficiency is high.
Technical solution of the present utility model is: coal bed gas well minitype motivation water tap, comprise casing, casing there is water supply connector, it is characterized in that in casing, there is hollow spindle at center, hollow spindle there is driven gear, this driven gear is connected with the driving gear on two hydraulic motor output shafts in casing, hydraulic motor each in hollow spindle both sides; Hollow spindle upper end is connected with water supply connector, and hollow spindle lower end is connected with drilling rod by crossover sub.
Be that drilling water faucet and drill motor function combine, be installed on derrick inner space and hanged the top drive drilling system held by tourist bus, from the direct rotary drill column in top, derrick space, rotary drilling, back reaming, circulating fluid, stacks (single) etc. can be completed.Preferred ambient temperature :-18 DEG C ~ 45 DEG C.
The utility model has the advantages that: 1, select low-speed big torque motor to drive, primary gear speed reducing, realize two fluid motor-driven hollow spindles, drive drilling rod to rotate, enough power (moment of torsion) is provided.2, adopting top to drive drilling system to instead of traditional rotating disk, drive the transfer, transmission system etc. of rotary disc box and complexity, is a kind of motorisation unit of high integration, time saving and energy saving, increases work efficiency.3, simple, the easy accessibility of structure.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structure diagram.
Fig. 2 is Fig. 1 side structure sketch.
Fig. 3 is the utility model hydraulic schematic diagram.
Detailed description of the invention
See Fig. 1-3, component title is as follows: casing 8, water supply connector 9, hollow spindle 10, driven gear 11, hydraulic motor 12, driving gear 13, pressure cap 14, bearing 15.
See Fig. 1,2, coal bed gas well minitype motivation water tap, comprises casing 8, casing 8 has water supply connector 9.In casing 8, there is hollow spindle 10 at center, hollow spindle 10 has driven gear 11, and this driven gear 11 is connected with the driving gear 13 on interior two hydraulic motor 12 output shafts of casing 8, hydraulic motor 12 each in hollow spindle 10 both sides; Hollow spindle 10 upper end is connected with water supply connector 9, and hollow spindle 10 lower end is connected with drilling rod 5 by crossover sub.
Important technological parameters
Specified hook carries: 400 kN.
Max. hook load: 600 kN.
Peak torque 12 kN m.
Maximum speed 120r/min.
Critical piece and function:
1, hydraulic motor 12, casing 8, hollow spindle 10(central axis), washing pipe assembly, driven gear 11, hydraulic motor 12, driving gear 13, black box, drop handle, drop handle pin, water supply connector 9(gooseneck), crossover sub, solenoid operated directional valve, Hydraulic Station etc.
2, drive drill string rotating, screw or unclamp drill string thread.
Main operational principle:
Hydraulic motor 12 driving gear wheel set (driving gear 13, driven gear 11) drives hollow spindle 10 to rotate, and drilling rod is connected on hollow spindle 10 by crossover sub.
Hollow spindle 10 is hollow-core constructions, and its top is connected with gooseneck through washing pipe, and inside can flow through mud to cool transmission case lubrication oil, drill bit and to return out drilling cuttings.Drop handle is then connected with well drilling traveling block, controls power swivel and moves up and down.
Drill down operator:
1, manually by first drilling rod and drill bit Chain clipper joint fastening good after, move to well head relevant position.
2, start winch and transfer unit head to elevator close to single drill string.
3, start the winch unit head that hoists and carry drilling rod to enough height, to well center, in lower going-into-well.
4, control rate of penetration with disk type brake, carry out creeping into operation.
5, when rod boring is close to afterbody, shuts down, make air spider block drilling rod, start unit head reversion, dismantle the connection of drilling rod and unit head.
6, mention unit head slightly, again lift by crane a drilling rod to certain altitude, to well center, make-up, starts unit head, screws two ends of drill screw thread, unclamp chuck, proceed to creep into operation.
Repeat aforesaid operations, until work of creeping into all terminates.
Pull out of hole operation:
1, utilize on suspension ring, elevator and carry drilling tool, expose one section of drilling rod, with chuck, drill string is sitting on well head.
2, start unit head reversion, dismantle drilling rod top screw thread, start lifting of winch unit head and drill string.
3, collapse end joint screw thread under loose drilling rod with hydraulic break out cylinder, use tong shackle.
4, transfer unit head, move drilling rod and enter pipe slacking block.
5, play next root drilling rod, repeat aforesaid operations, forms one and pull out of hole and circulate, always by till drill string all trips out in well.Unit head lower end crossover sub screw thread is connected with drill rod thread, proposes drill string.
See Fig. 3, two hydraulic motors 12 can realize series connection (not needing large moment of torsion) and (needing large moment of torsion) operation, i.e. two gears in parallel.Can realize rotating and reverse.
