Description
Technical field
The utility model relates to a kind of directional well device, particularly a kind of horizontal well directional well drill string antiseize device.
Background technology
In horizontal well and directional well drilling work progress, when the contact area of drill string and the borehole wall is large, between drill string and the borehole wall, because the effect of drilling fluid easily causes, drill string is sticky to be stuck on the borehole wall, in order to wellbore construction operation can be proceeded, now, then need to carry out unfreezing operation to the drill string of sticky card, make wellbore construction operation there is larger risk.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of horizontal well directional well drill string antiseize device.
Its technical scheme is: comprise interior matching thread, device body, through hole, topping machanism, drill through screw thread, fit on screw thread, through hole upper end internal side wall is provided with interior matching thread, the lower end outer setting of device body has fit on screw thread, outer wall in the middle part of device body is provided with topping machanism, the outer wall of device body bottom is provided with and drills through screw thread, topping machanism comprises back-moving spring, piston, tubular piston bar, bite, teeth, teeth groove, bite standing groove, pressure reduction nozzle, back-moving spring is provided with on the top of topping machanism, piston rod is provided with in the bottom of back-moving spring, be provided with piston on the piston rod, bite is fixed on bite standing groove, bite and bite standing groove junction are provided with multiple teeth, the inside wall of bite standing groove is provided with multiple teeth groove, the lower outside wall of bite standing groove is provided with pressure reduction nozzle.
Above-mentioned bite is hinged in bite standing groove, and described teeth and teeth groove engage each other.
The beneficial effects of the utility model are: the utility model effectively can solve existing drill string drill string easily sticky antiseized card of horizontal well directional well be stuck on the borehole wall in work progress in well, be provided with topping machanism, effectively can bore the diameter of large horizontal well or directional well, thus contribute to the contact area reducing drill string and horizontal well or directional well, and then the generation that drill string glues the phenomenon be stuck on the borehole wall can be reduced, improve the construction safety of horizontal well and directional well, and cutting tool arm opens, shrinks control conveniently, tool arm is replaceable, convenient for maintaining.
