Abstract

The utility model relates to a petroleum well drilling tool, particularly to a rotary guiding well drilling tool which is mainly composed a slurry generator, a sealing barrel, a measuring instrument, a motor, a decelerator, an eccentric joint, a center pipe, a body and a corrugated pipe, wherein the lower part of the slurry generator in an inner cavity of the utility model is also provided with the sealing barrel, and the measuring instrument, the decelerator, the eccentric joint and the center pipe are orderly arranged in annular cavities of the sealing barrel and the body; the center pipe is provided with a spherical key structure connected with the body, and the decelerator is connected with the eccentric joint by a spline; the eccentric joint is connected with the center pipe through bearings, and the sealing corrugated pipe is arranged between the center pipe and the tail end of the body. The utility model can arbitrarily adjust the drilling orientation and angle of a drill bit without lifting a drill so as to greatly simplify operating procedures, and apart from the slurry generator, all moving components are immersed in lubrication oil to work so that the utility model has long service life.

Description

Rotary steering drilling tool
Technical field
The utility model relates to a kind of oil drilling tool, especially a kind of rotary steering drilling tool.
Background technology
At present, often need to change the orientation and the angle of creeping in rotating disk horizontal well drilling process, conventional measure is to carry brill to be lowered to special instrument and instrument again, and this will waste the plenty of time, also be unfavorable for downhole safety.
Summary of the invention
At the above-mentioned on-the-spot practical problem that exists, developed the utility model-guide drilling tool, by ground just can control well under the drill bit orientation and the angle of creeping into.
The utility model mainly is made up of slurry generator 1, sealing drum 2, measurement and control instrument 3, motor 4, reducer 5, eccentric joint 6, central tube 7, body 8 and bellows 9, sealing drum 2 has also been designed in the bottom of instrument inner chamber slurry generator 1, in the annular space of sealing drum 2 and body 8 measuring apparatus 3, reducer 5, eccentric joint 6, central tube 7 is housed successively; Central tube 7 has a spherical bond structure to connect with body 8, and reducer 5 adopts splined with eccentric joint 6; Eccentric joint 6 and central tube 7 connect by bearing, between central tube 7 and body 8 ends seal bellows 9 are housed.
When needs are adjusted orientation that drill bit creeps into and angle, the utility model can be measured the rotating speed of body 8 by measurement and control instrument 3, again according to the bearing data on ground, control motor 4 rotates with a certain speed and direction, by reducer 5 and eccentric joint 6 central tube 7 is swung around the centre of sphere, the speed of its swing is identical with the rotating speed of body 8, and direction is opposite.This moment, the central stationary of central tube 7 was motionless in the orientation that we set, and adjusted the orientation that drill bit creeps into and the purpose of angle thereby reach.The utility model need not be carried boring and just can adjust orientation and the angle that drill bit creeps into arbitrarily, simplified operation procedure greatly, and except that mud generator 1, all moving components is immersed in the lubrication oil all and works, long working life.
Description of drawings
Fig. 1 the utility model structural representation
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
As shown in Figure 1: the utility model mainly is made up of slurry generator 1, sealing drum 2, measurement and control instrument 3, motor 4, reducer 5, eccentric joint 6, central tube 7, body 8 and bellows 9, sealing drum 2 has also been designed in the bottom of instrument inner chamber slurry generator 1, in the annular space of sealing drum 2 and body 8 measuring apparatus 3, reducer 5, eccentric joint 6, central tube 7 is housed successively; Central tube 7 has a spherical bond structure to connect with body 8, thereby the driving torque of body 8 is passed to central tube 7, and it also passes to body 8 with the pressure of the drill of central tube 7 simultaneously, and it makes that also central tube 7 can be around its centre of sphere swing in addition; Reducer 5 adopts splined with eccentric joint 6; Eccentric joint 6 and central tube 7 connect by bearing, when motor 4 rotates, eccentric joint 6 is rotated, thereby makes central tube 7 around centre of sphere swing by reducer 5, central tube 7 around the speed of centre of sphere swing and direction by measurement and control instrument 3 decisions.Between central tube 7 and body 8 ends seal bellows 9 is housed.Slurry generator 1 provides electric energy for measurement and control instrument 3 and motor 4.Sealing drum 2 and bellows 9 are used to prevent that the inside and outside mud of guide drilling tool from entering in the instrument.
The utility model operating principle: when not needing to adjust orientation that drill bit creeps into and angle, motor 4 is not worked, and central tube 7 and body 8 rotate synchronously, and drill bit will be along original orientation and angle drilling well; When needs are adjusted orientation that drill bit creeps into and angle, at first measurement and control instrument 3 is measured the rotating speed of body 8, again according to the bearing data on ground, control motor 4 rotates with a certain speed and direction, by reducer 5 and eccentric joint 6 central tube 7 is swung around the centre of sphere, the speed of its swing is identical with the rotating speed of body 8, and direction is opposite.This moment, the central stationary of central tube 7 was motionless in the orientation that we set, and adjusted the orientation that drill bit creeps into and the purpose of angle thereby reach.
