Abstract
The present invention relates to a drill for drilling wells. A drill rod of the drill is composed of a slurry passage, a high-pressure oil inlet passage, an oil return passage and a steel rope; the drill rod can be flexibly wound on a roller; the drill rod does not need to be unloaded or connected when the drill is descended. The slurry can be normally circulated, and the phenomena of pumping and spraying and diameter reduction can be prevented from happening. A hydraulic motor is driven by high-pressure oil, when the drill drills, the drill rod does not rotate. The labor intensity of operators is reduced, and the drilling efficiency and the economic benefit are increased. The drill for drilling wells can be matched with drilling machines in various types, and can drill wells with a depth of 5000m when matched with 130 drilling machines in a Daqing II type.
Description
The present invention relates to a kind of drilling well drilling tool.
Drilling well at present all is a rigidity with the drilling rod of drilling tool.The well dynamic machine is that power adopts single-head screw pump or turbodrill with mud.In creeping into, need often connect or dismantle drilling rod, increase activity duration and labour intensity; Can not circulating mud during trip-out, easily cause and take out spray and undergauge; The trip-out time is long, landwaste can not on return, be hampered when boring down again.With mud is power, and mud is required height, and the engine wearing and tearing are big.Especially to the creeping into of deep-well, efficient obviously descends.Only be applicable to 1200 meters with interior creeping into.
The object of the present invention is to provide a kind of flexible hydraulic drilling tool.When creeping into, drilling rod does not rotate drilling rod and is flexibility and can need not dismantles or connect when making a trip on cylinder, and mud can normal circulation, can obviously increase economic benefit and improve drilling efficiency.
The present invention realizes so in conjunction with the accompanying drawings.Flexible hydraulic drilling tool is dimerous by hollow drill and hydraulic motor.
Accompanying drawing 1,2 has specifically provided the structural representation of hollow drill.The hollow drill outside is made up of the wire rope (7) of oil inlet passage (13), drainback passage (14), slurry channel (8) and a booster action of high-temperature resistant rubber (10) parcel.Two ends are separately fixed on upper and lower fittings body (11), (6) with adhesive and taper sheath (5), and anti-torsion spring (9) is twined to resist the torsion that produces when hydraulic motor rotates in the drilling rod outside.
Accompanying drawing 3,4 has specifically provided the hydraulic motor structure schematic diagram.The hollow power output shaft of hydraulic motor (15) that useful hydraulic oil drives below hollow drill.The last end joint of hydraulic motor has oil inlet passage (26), drainback passage (25) and slurry channel (27), and is communicated with corresponding oil inlet passage, drainback passage and slurry channel on the hollow drill.
After arriving drill bit, the flexible hydraulic drilling tool of making according to said structure, the mud that got off by the drilling rod slurry channel slurry channel by hydraulic motor sprays.The rotation of power output shaft is to be entered in the motor by the high-pressure and hydraulic oil that oil input channel comes, and act on output shaft and the oil distribution shaft gear (20), because the oil distribution shaft gear position is constant, the hydraulic coupling promotion output shaft that therefore acts on the output shaft blade tooth also clockwise rotates.Hydraulic motor belongs to the gear vane type, and along with the rotation high-voltage oil cavity volume of axle increases, hydraulic oil is constantly imported, and constantly the reducing of low pressure oil pocket enters drainback passage to low pressure oil.Low pressure oil after the work is returned ground by the drainback passage of drilling rod, returns hydraulic motor after pressurization, constitutes closed circuit.
The wire rope lifting draws effect, the two ends of wire rope to use taper cutting ferrule and clamping nut (2) to be fixed on the upper and lower fittings body respectively.Slurry channel, the two ends of high-pressure oil passage and drainback passage are fixed on the upper and lower fittings body with taper sheath respectively.The connection of drilling rod connects by rotation box cupling (1).
When using drilling tool provided by the invention to creep into, drilling rod does not rotate, and can dig a directional well.Because drilling rod is flexible need not dismantling when making a trip on cylinder, improves drilling efficiency.Mud can normal circulation when pulling out of hole, and can prevent to take out spray and the undergauge generation of picture now.Alleviate operating personnel's labour intensity.Drilling tool provided by the invention, can with the supporting use of all types of rigs.Supportingly to grand celebration II type-130 rig, can bore the dark well of 5000m.
