Abstract
The invention relates to an inclinometer insulation short section. The inclinometer insulation short section comprises a short section substrate and a fixed sleeve fixedly connected with the outer side of the short section substrate, wherein the short section substrate comprises a pair of joints which are embedded in each other through T-shaped keys evenly distributed; the positions, corresponding to the T-shaped keys evenly distributed, of the outer side of the short section substrate are provided with abrasion-resistant sleeves, and the axial lengths of the abrasion-resistant sleeves are greater than the axial lengths of the T-shaped keys evenly distributed; insulators are arranged between the short section substrate and the abrasion-resistant sleeves and between the joints and the T-shaped keys evenly distributed respectively. Insulators are also arranged between the fixed sleeve and the abrasion-resistant sleeves. The joints are in a cylinder shape. The inclinometer insulation short section has the advantages of being high in whole strength and good in reliability, having the low requirement for strength of insulation materials, and being compact in structure, small in axial size, capable of being suitable for whole-series drill collars, and high in universality.
Description
Technical field
The present invention relates to a kind of directional tool insulating short section.
Background technology
Insulating short section is electromagnetic wave wireless drilling inclinometers and other similar underground loggings, with the vitals that bores instrument.Owing to will bearing pressure, moment of torsion, the bending load in drilling process on the one hand, also to there is certain electrical insulation capability simultaneously, make this have high requirement to the insulation materials in insulating short section.Existing insulating short section technology is all unilaterally to improve the requirement of insulation materials strength character, and this is difficult to meet the needs of practical application to a great extent.
Summary of the invention
The object of this invention is to provide a kind of directional tool insulating short section, to overcome prior art above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
A kind of directional tool insulating short section, comprises pipe nipple matrix and the fixed cover that is fixed in described pipe nipple matrix outside, and described pipe nipple matrix comprises a pair of by uniform T-shaped key chimeric joint mutually; The axial length that the position corresponding with described uniform T-shaped key, described pipe nipple matrix outside is provided with wear-resistant sleeve and described wear-resistant sleeve is greater than the axial length of described uniform T-shaped key; Between described pipe nipple matrix and wear-resistant sleeve and between described joint and uniform T-shaped key, be equipped with isolator.
Further, the free end of described joint is equipped with pin thread in order to connect drilling tool, one of them joint shoulder place is provided with external screw thread, described fixed cover is provided with the internal thread matching with described shoulder place external screw thread, and one of them joint is fixedly connected with fixed cover by the cooperation of described external screw thread and internal thread.
Selectable, the free end of described joint be respectively equipped with pin thread with box in order to be connected drilling tool, described male joint shoulder place is provided with external screw thread, described fixed cover is provided with the internal thread matching with described shoulder place external screw thread, and described male joint is fixedly connected with fixed cover by the cooperation of described external screw thread and internal thread.
Further, between described fixed cover and wear-resistant sleeve, be also provided with isolator.
Preferably, described joint is cylindric.
Beneficial effect of the present invention is: bulk strength is high, good reliability; Lower to insulation materials requirement of strength; Compact conformation, axial dimension is little; Can adapt to complete series drill collar, highly versatile.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the longitudinal sectional view of directional tool insulating short section described in the embodiment of the present invention.
In figure:
1, pipe nipple matrix; 2, fixed cover; 3, wear-resistant sleeve; 4, isolator; 5, uniform T-shaped key; 6, joint.
The specific embodiment
As shown in Figure 1, a kind of directional tool insulating short section described in the embodiment of the present invention, comprises pipe nipple matrix 1 and is fixed in the fixed cover 2 in described pipe nipple matrix 1 outside, described pipe nipple matrix 1 comprises a pair of by the mutual chimeric joint 6 of uniform T-shaped key 5; The axial length that the position corresponding with described uniform T-shaped key 5, described pipe nipple matrix 1 outside is provided with wear-resistant sleeve 3 and described wear-resistant sleeve 3 is greater than the axial length of described uniform T-shaped key 5; Between described pipe nipple matrix 1 and wear-resistant sleeve 3, between described fixed cover 2 and wear-resistant sleeve 3 and be equipped with isolator 4 between described joint 6 and uniform T-shaped key 5.Described joint 6 is cylindric.
The free end of described joint 6 is equipped with pin thread in order to connect drilling tool, one of them joint shoulder place is provided with external screw thread, described fixed cover 2 is provided with the internal thread matching with described shoulder place external screw thread, and one of them joint 6 is fixedly connected with fixed cover 2 by the cooperation of described external screw thread and internal thread.Selectable scheme is: or the free end of described joint 6 be respectively equipped with pin thread with box in order to be connected drilling tool, described male joint shoulder place is provided with external screw thread, described fixed cover 2 is provided with the internal thread matching with described shoulder place external screw thread, and described male joint 6 is fixedly connected with fixed cover 2 by the cooperation of described pin thread screw thread and box screw thread.
When concrete application: isolator 4 adopts glass fiber reinforced epoxy resin to form.
Directional tool insulating short section described in the embodiment of the present invention is in the drilling process of down-hole, and described uniform T-shaped key 5 bears Tensile or Compressive Loading and torsional load, described wear-resistant sleeve 3 Bending load.No matter any load, isolator 4 mainly bears compressive stress, can give full play to the strength characteristics of material, meets the severe working condition requirement in down-hole.Described uniform T-shaped key 5 takes full advantage of structural advantage, and loaded area is large, compact conformation, and axial dimension shortens greatly.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
