Description
Technical field
The utility model belongs to the design and manufaction technical field of oil drilling tool, and particularly relate to a kind of righting drag reduction adapter device, this device is one of well drilling pipe column assembly, is connected on drilling rod or drill collar, can be used in straight well or inclined shaft.
Background technology
At present, enter centralizer under often running in domestic drilling centralizer field to be hampered, righting effect is undesirable, and drilling tool and wall friction resistance large, the problems such as energy utilization efficiency is not high, this not only exacerbates the wearing and tearing of drilling tool, and extends construction period, consumes the input of unnecessary human and material resources.
Summary of the invention
The object of the invention is: provide a kind of and can effectively reduce well drilling pipe column and wall friction power and easily change the drilling centralizer of wear-out part.
Reaching the technical scheme that above requirement adopts is: a kind of righting drag reduction adapter device, this device comprises body mandrel, centering ring and baffle ring, drilling well button is provided with at the upper and lower side of described body mandrel, be provided with centering ring shoulder block near drilling well mother buckle button side, pin thread side is then provided with baffle ring screw thread; Centering ring is arranged three spiral stream guidance grooves, be crisscross arranged ball seat screw thread between spiral stream guidance groove, and ball seat is connected with centering ring by screw thread; The outside radian of ball seat is consistent with centering ring, and in the middle of described ball seat, be provided with cylindrical hole, cylindrical hole aperture, upper end is less than lower stomidium aperture, and steel ball is arranged in ball seat cylindrical hole; By the screw thread of body mandrel, baffle ring is installed in centering ring lower end, uniform on baffle ring face through threaded bore is set, backing-up screw along the threaded bore on baffle ring deeply in the groove of body mandrel.
Beneficial effect of the present invention: this utility model drilling centralizer relies on rotary steel ball to solve centralizer to enter well and be easily obstructed, the difficult problem that drilling tool righting effect is undesirable, and the sliding friction of centralizer and the borehole wall (sleeve pipe) can be become rolling friction when drilling well, effectively reduce the frictional resistance of drilling tool, improve the energy utilization efficiency of drilling tool, extend drill tool life, wherein dismountable ball seat ensure that wear part quick-replaceable and does not affect construction period, in addition, guiding gutter on centering ring can also play guide functions, prevent circulation throttling shaft bottom from building the pressure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is main TV structure cross-sectional schematic of the present invention; Fig. 2 is the utility model stereogram.
Detailed description of the invention
A kind of righting drag reduction adapter device, as shown in Fig. 1 and 2, this device comprises body mandrel 1, centering ring 2 and baffle ring 6, is provided with drilling well button at the upper and lower side of described body mandrel 1, be provided with centering ring 2 shoulder block near drilling well mother buckle button side, pin thread side is then provided with baffle ring screw thread; Centering ring 2 is arranged three spiral stream guidance grooves, be crisscross arranged ball seat screw thread between spiral stream guidance groove, and ball seat 3 is connected with centering ring by screw thread; The outside radian of ball seat 3 is consistent with centering ring 2, and in the middle of described ball seat 2, be provided with cylindrical hole, cylindrical hole aperture, upper end is less than lower stomidium aperture, and steel ball 4 is arranged in ball seat cylindrical hole; By the screw thread of body mandrel, baffle ring 6 is installed in centering ring 2 lower end, uniform on baffle ring face through threaded bore is set, backing-up screw 5 along the threaded bore on baffle ring deeply in the groove of body mandrel.
In practice, this device adopts three parts composition, body mandrel, centering ring and baffle ring.Wherein the upper and lower side of body mandrel is provided with drilling well button, and be provided with centering ring shoulder block near box side, pin thread side is provided with baffle ring screw thread; Centering ring is with three spiral stream guidance grooves, and several rows being provided with all part cloth between spiral stream guidance groove are interlocked ball seat screw thread, and ball seat is connected with centering ring by screw thread; The outside radian of ball seat is consistent with centering ring, cylindrical side is provided with screw thread, cylindrical hole is provided with wherein, wherein upper end cylindrical hole is slightly less than lower stomidium, formation step like this can ensure that bead is contained in ball seat cylindrical hole and externally not come off, and when being arranged on centering ring bottom have mandrel in the presence of, 360 ° of rotations can be ensured; After bead loaded onto by ball seat, be connected with centering ring, be then enclosed within by centering ring on body mandrel, install baffle ring in centering ring lower end by the screw thread of mandrel, centering ring like this can rotate and not come off on mandrel, and easily changes; Baffle ring is provided with the threaded bore in some equal portions, and after baffle ring puts in place, at this hole cartridge screw, screw lower end is goed deep in the groove of body mandrel, so can play the locking effect of baffle ring.
