Abstract
The utility model is related to a kind of brill super short radius horizontal trajectory control devices, it is characterised in that：Be by：Poor position device, flex-stem, flexible orientation guide pipe, bit body, drill bit, bearing, drilling rod and guide sleeve composition, the top of poor position device is equipped with guide sleeve and drilling rod successively, bearing is equipped on poor position device, it is equipped with flexible orientation guide pipe in the lower part of poor position device, one end of flex-stem connect setting with poor position device in flexibility orientation guide pipe, and the other end of flex-stem is connect with bit body and drill bit.The utility model bores super short radius horizontal trajectory control device, it solves wellbore construction and goes out layer, guide pipe easy fracture, the overwork damage of flex-stem torque, the problems such as track cannot being made to be completed by design requirement, greatly improves work efficiency, ensure that construction quality, reduces drilling cost.
Description
Technical field
The utility model belongs to drilling equipment technical field, is suitable in construction ultra-short radius, radial horizontal drilling engineering
Middle track control device, more particularly to a kind of brill super short radius horizontal trajectory control device.
Background technology
Currently, the country in prior art super short radius horizontal drilling engineering construction, is packed into soft using flex-stem
Property guide pipe in, front end connects drill bit, and guide pipe is connected to bit body rear end, and torque is transmitted by turntable, and flex-stem is made to do
It draws guide pipe while 360 degree rotation broken rock to creep by horizontal direction, track is difficult to control, and bit pressure is applied to always flexible drilling
Rod rear end makes to generate chucking power between guide pipe and stratum, and guide pipe can only do gliding motility due to applying bit pressure.Friction resistance
Power increases as track lengthens, and so that track is lengthened can only increase bit pressure, and consequence is track gradually downlink, leads to layer, is led
To tube capacity easy fracture.Flex-stem torque overwork damage, it is impossible to track be made to be completed by design requirement.
Invention content
The utility model overcomes above-mentioned defect, it is therefore an objective to be high working efficiency, reduce drilling cost, provide one
Kind bores super short radius horizontal trajectory control device.
The utility model bores super short radius horizontal trajectory control device content Description：
The utility model bores super short radius horizontal trajectory control device, it is characterised in that：Be by：Poor position device, flexibility
Drilling rod, flexible orientation guide pipe, bit body, drill bit, bearing, drilling rod and guide sleeve composition, the top of poor position device is equipped with successively leads
To set and drilling rod, it is equipped with bearing on poor position device, flexible orientation guide pipe, one end of flex-stem are equipped in the lower part of poor position device
Setting is connect with poor position device in flexibility orientation guide pipe, the other end of flex-stem is connect with bit body and drill bit.
The utility model bores super short radius horizontal trajectory control device, solves wellbore construction and goes out layer, guide pipe is easy
The problems such as fracture, the overwork of flex-stem torque damages, track cannot be made to be completed by design requirement, greatly improve work efficiency,
It ensure that construction quality, reduce drilling cost.
Description of the drawings
Fig. 1 is to bore super short radius horizontal trajectory controling device structure diagram；
In figure：1 it is poor position device, 2 be flex-stem, 3 be flexible orientation guide pipe, 4 be bit body, 5 be drill bit, 6 is axis
It holds, 7 be drilling rod, 8 be guide sleeve.
Specific implementation mode
The utility model, which bores super short radius horizontal trajectory control device and is achieved in that, to be made to have below in conjunction with the accompanying drawings
Body explanation.
See Fig. 1, bore super short radius horizontal trajectory control device, be by：Poor position device 1, flex-stem 2, flexible orientation
Guide pipe 3, bit body 4, drill bit 5, bearing 6, drilling rod 7 and guide sleeve 8 form, the top of poor position device 1 be equipped with successively guide sleeve 8 and
Drilling rod 7 is equipped with bearing 6 on poor position device 1, and flexible orientation guide pipe 3, one end of flex-stem 2 are equipped in the lower part of poor position device 1
Setting is connect with poor position device 1 in flexibility orientation guide pipe 3, the other end of flex-stem 2 is connect with bit body 4 and drill bit 5.
The utility model changes bit pressure using theory of mechanics difference position " lifting from the top and puting down " and is applied to flex-stem rear end always, makes
Flex-stem keep be broken rock again traction state, according to experiments have shown that track downwards than push away guide pipe track upwards slow 13.5 times,
It is calculated according to ratio and replaces underground propulsion bit pressure, after 1,35 meters of drilling, change bit pressure pushes away guide pipe and creeps into 10 centimeters, you can
Realize that drilling trace presentation advances wave upon wave, it is ensured that not going out layer again can reducing friction resistance.
When work：Poor position device 1 above carries change bit pressure and is applied to 2 end of flex-stem, makes the holding of flex-stem 2 i.e. broken rock again
Traction state, at this time drill bit creep into forward, due to when track extends, because elasticity causes drill bit to run down with gravity factor.
Bit pressure is applied to 3 end of flexible orientation guide pipe by a device 1 of being on duty decentralization to bearing 6, by bearing 6, and drill bit bores upwards at this time
Into.And so on adjusting poor position device makes drilling trace presentation advance wave upon wave.
The utility model bores super short radius horizontal trajectory control device, solves wellbore construction and goes out layer, guide pipe is easy
The problems such as fracture, the overwork of flex-stem torque damages, track cannot be made to be completed by design requirement, greatly improve work efficiency,
It ensure that construction quality, reduce drilling cost.
