Description
Technical field
The utility model relates to a kind of drilling engineering equipment, particularly a kind of automatic rotation steerable drilling device.
Background technology
Along with the development of petroleum industry, in order to obtain better economic benefit, need to develop deep-well, ultradeep well, extended reach well and long apart from horizontal well, and usually will be on more complicated stratum, structural belt drilling well as steep in height.These are all had higher requirement to directional drill tool.The directional drill tool that the down-hole motor of take is at present master can not meet the requirement of modern drilling technology, and in oil drilling industry, the horizontal movement of Oil/gas Well is increasing.Boring in the process of the well that horizontal movement is larger in the mode of creeping into of sliding, can produce very large frictional resistance moment of torsion.Frictional resistance moment of torsion is crossed conference and is caused a series of problem, and as Tubing Buckling distortion, the pressure of the drill cannot be applied on drill bit, the tool wears such as drill string, sleeve pipe etc., and serious even can cause the generation of drilling failure.It is the very necessary work of extended reach well, directional well drilling that antifriction lowers is turned round.
Domestic and international existing antifriction lowers is turned round instrument now, has plenty of the less elastomeric material of the friction factor of employing and reduces moment of torsion, has plenty of by rolling bearing and reduces moment of torsion.But these some problems of instrument ubiquity: the instrument having cannot be applied in high temperature well section; Some tool applications effect in barefoot interval is bad, even cannot use; The needs that also have increase a lot of joints, although these joints can be turned round by antifriction lowers, too much joint has increased cost to a great extent, and wellbore stability is caused to adverse effect.And all existing instruments are all to removing not too large help of landwaste.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of automatic rotation steerable drilling device is provided.
Its technical scheme is: comprise rotary drill column, drill bit, fairlead, controller, flexible piece, bearing, the centre of rotary drill column is rotary drill rod, the two ends of described rotary drill rod are rotary connecting joint, the end of rotary drill column connects drill bit, the diameter of rotary drill rod is less than the diameter of rotary connecting joint, the outside of rotary drill rod is provided with fairlead, bearing is installed respectively at described fairlead and the two ends of rotary drill rod, static controller in the middle cavity of fairlead and rotary drill rod, the outside of described fairlead is provided with three groups of diamond grooves, diamond groove inside connects respectively flexible piece.
The outside of above-mentioned fairlead is cylindrical structural, and the cylindrical structural of fairlead is provided with arc groove.
The outside of above-mentioned fairlead is provided with alignment sensor.
The beneficial effects of the utility model are: improved drilling efficiency, guaranteed the accuracy of drilling well, avoided the elasticity of torsion of drill string to be out of shape the unsettled problem in tool face azimuth causing, guaranteed that well track is accurate, reduce the frictional force that rotary drill column is subject to, guaranteed drilling depth.
