Abstract
The utility model discloses a kind of oil-water well underground work pipe column to be oriented to plug, including plug body, the plug body are provided with guide wheel in itself radial direction, and wherein guide wheel outermost rolling surface edge will protrude plug body outer wall.The plug body opens up the guided wheel slot for being used to install guide wheel of radial direction.Wheel shaft is installed at the guide wheel center, and guide wheel is arranged on wheel shaft by bearing.The plug outer body also sets up gland, the gland inwall and plug body outer wall open up corresponding horizontal semicircle groove simultaneously, after above-mentioned two transverse direction semicircle groove fastens, wheel shaft is fixed in horizontal semicircle groove, and the guide wheel outermost rolling surface edge will protrude gland outer wall.Uniform two screwed hole in the middle part of the gland, and be fixed on by counterbore pin on plug body.Type leading wheel framework is added on the plug of script.Tubular column system can be made through at casing damage, to cross the obstruction of the things such as side-wall begriming wax deposition in the section automatic guide such as hole deviation, horizontal well.
Description
Technical field
Oil field downhole tool accessory is the utility model is related to, specifically a kind of oil-water well underground work pipe column is oriented to
Plug.
Background technology
Also increasing as oil field enters middle and later periods operational mode and deep-well, directional well quantity, oil field is originally suitable straight
The completion of well, working string are difficult to lower well operations due to reasons such as hole deviations.In addition also due to internal surface of sleeve pipe fouling knot in straight well
The reasons such as wax, make latus rectum change cause working string to be difficult to lower well operations, even result in the therefore breakage of various downhole tools, cause
Oil-water well service life reduction, or even scrap, huge economic loss is brought to oil field.
By retrieval, the plug with guiding mechanism is not found.
The content of the invention
The purpose of this utility model is that providing a kind of oil-water well underground work pipe column is oriented to plug, on the plug of script
Add type leading wheel framework.Directive wheel external diameter and circumference uniform distribution reasonable quantity optimization design, can make tubular column system in the design
In the section automatic guide such as hole deviation, horizontal well, through at casing damage, the obstruction of the things such as side-wall begriming wax deposition is crossed.
In order to reach above-mentioned purpose, the utility model employs following technical scheme, a kind of oil-water well underground work pipe column
Plug is oriented to, including plug body, the plug body are provided with guide wheel, wherein guide wheel outermost side roll in itself radial direction
Face edge will be protruded outside plug body outer wall.The plug body opens up the guided wheel slot for being used to install guide wheel of radial direction.It is described to lead
Wheel shaft is installed at wheel center, and guide wheel is arranged on wheel shaft by bearing.The plug outer body, which is also set up, prevents what guide wheel from deviating from
Gland.The gland inwall and plug body outer wall open up corresponding horizontal semicircle groove, two above-mentioned transverse directions half simultaneously
After round recessed fastens, wheel shaft is fixed in horizontal semicircle groove, and the guide wheel outermost rolling surface edge will be protruded outside gland
Outside wall.
Uniform two screwed hole in the middle part of the gland, and be fixed on by counterbore pin on plug body.
The guide wheel is evenly equipped with 6.
The gland is also provided with 6, and a gland is installed between each two guide wheel.
Compared to prior art, the utility model has the advantages that：
The utility model is arranged on oil-water well operation tubing string bottom, during going into the well, due to the presence of guide wheel, makes tubing string
Obstacle position and the damaged parts such as the box cupling step in well, the fouling wax deposition in well are crossed easily, improve task difficulty of going into the well,
Improve measure operating speed.
（1）Alternative existing plug, increase working string system enter well speed.
（2）Avoid tubing string bottom from hitting the destructiveness of inclined shaft internal surface of sleeve pipe, mitigate task difficulty of going into the well.
Brief description of the drawings
Fig. 1 is the structural representation that a kind of oil-water well underground work pipe column of the present utility model is oriented to plug；
Fig. 2 is the guide wheel position radial section schematic diagram that a kind of oil-water well underground work pipe column is oriented to plug；
In figure：Body 1, guide wheel 2, wheel shaft 3, counterbore pin 4 and gland 5.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing is only to refer to
With purposes of discussion, not it is used for being any limitation as the utility model.
As shown in accompanying drawing 1 to 2, a kind of oil-water well underground work pipe column is oriented to plug, mainly by body 1, guide wheel 2, wheel shaft
3, counterbore pin 4 and gland 5 form.Guide wheel 2 is arranged on wheel shaft 3, is placed on together in the guided wheel slot of body 1, and with the envelope of gland 5
Firmly, described gland 5 uniform two screwed hole in middle part vertically.The gland 5 is fixed on body 1 by counterbore pin 4.
It is semi-circular that the described bottom side of body 1, which is provided with 6 axially uniform bottom lands corresponding with the outside dimension of guide wheel 2,
Guided wheel slot.Gland 5 divides for 6, and one is set between each two wheel, buckles and is fixed on counterbore pin 4 on body 1.
One section of semicircle cambered surface groove corresponding with the size of wheel shaft 3 is circumferentially respectively provided with the described groove side of body 1.It is described
The inner side of gland 5 be circumferentially respectively provided with one section of semicircle cambered surface groove corresponding with the size of wheel shaft 3.Two above-mentioned horizontal semicircle grooves
After fastening, wheel shaft is fixed in horizontal semicircle groove.
In field conduct, according to Fig. 1, the utility model is arranged on oil-water well operation tubing string bottom, during going into the well, by
In the presence of guide wheel, tubing string is set to cross obstacle position and the damaged parts such as the box cupling step in well, fouling wax deposition in well easily,
Task difficulty of going into the well is improved, improves measure operating speed.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the scope of the claims of the present utility model, its
He uses the equivalence changes of the utility model patent spirit, all should all belong to the scope of the claims of the present utility model.
