Abstract
The utility model provides a broken drill rod guiding device for underground accidents, which belongs to the technical field of drill rods and aims to solve the problems that when the existing deep well is drilled, when the drill rod is broken or the slide wire falls in the hole, the drill rod is easy to lean against the edge, the drill rod head can not be found, the drill rod is difficult to withdraw, and construction accidents occur; the device comprises a pilot tube and a taper tube, wherein the pilot tube is in threaded connection with the taper tube; an oblique notch is formed in one end, far away from the taper pipe, of the pilot pipe; the inner side wall of the pilot tube is fixedly provided with a strong magnet; a threading die is fixedly arranged on the inner side wall of the conical tube, and the axis of the threading die is collinear with the axis of the conical tube; fix the drill pipe in certain extent through leading the positive pipe, hold the drilling rod through leading the strong magnet on the positive pipe, utilize the inside threading die of taper pipe to carry out the tapping to the drilling rod, couple together drilling rod and leading positive ware fixed connection, take out the drilling rod, effectively solve the problem that the drilling rod can't be taken out, avoided the useless condition that falls of well.
Description
Technical Field
The utility model relates to a drilling rod technical field specifically is disconnected drilling rod of accident leads positive ware in the pit.
Background
In deep well construction, drill pipes are often used for drilling. When the degree of depth of punching is darker, in case the drilling rod product is because of the quality problem, the drilling rod appears absolutely or the smooth silk problem, appears the drilling rod easily and leans on the limit, can not find the condition of drilling rod head, can't in time take out disconnected drill bit drilling rod, can appear the construction accident, can cause the useless condition of falling of whole well even, causes huge loss.
SUMMERY OF THE UTILITY MODEL
The technique that exists is not enough to the aforesaid, the utility model aims at providing a disconnected drilling rod of accident leads positive ware in pit, fixes the drill pipe in the certain limit through leading positive pipe, holds the drilling rod through leading strong magnet on the positive pipe, utilizes the inside die of taper pipe to carry out the tapping to the drilling rod, couples together drilling rod and leading positive ware fixed connection, takes out the drilling rod, effectively solves the problem that the drilling rod can't take out, has avoided the useless condition that falls of well.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the underground accident breakage drill pipe guide device is characterized by comprising a guide pipe and a taper pipe, wherein the guide pipe is in threaded connection with the taper pipe; an oblique notch is formed in one end, far away from the taper pipe, of the pilot pipe; the inner side wall of the pilot tube is fixedly provided with a strong magnet; and a threading die is fixedly arranged on the inner side wall of the conical tube, and the axis of the threading die is collinear with the axis of the conical tube.
Preferably, the cross-sectional area of the taper pipe gradually decreases from the direction close to the pilot pipe to the direction far away from the pilot pipe.
Preferably, still be fixed on the intraductal lateral wall of leading and be equipped with the separation blade, the strong magnet passes through the separation blade is fixed to be set up in leading on the intraductal lateral wall.
The beneficial effects of the utility model reside in that: this design is fixed the drill pipe in certain extent through leading the positive pipe, holds the drilling rod through leading the strong magnet on the positive pipe, utilizes the inside threading die of taper pipe to carry out the tapping to the drilling rod, couples together drilling rod and leading positive ware fixed connection, takes out the drilling rod, effectively solves the problem that the drilling rod can't take out, has avoided the useless condition that falls of well.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of a downhole accidental breakage drill pipe guider provided by the embodiment of the invention.
Description of reference numerals:
a baffle plate 1, a strong magnet 2, a pilot tube 3 and a taper tube 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figure 1, the downhole accidental breakage drill pipe guide device comprises a guide pipe 3 and a taper pipe 4, wherein the guide pipe 3 is in threaded connection with the taper pipe 4; an oblique notch is formed in one end, far away from the conical pipe 4, of the pilot pipe 3; the inner side wall of the pilot tube 3 is fixedly provided with a strong magnet 2; a threading die is fixedly arranged on the side wall of the inner part of the taper pipe 4, and the axis of the threading die is collinear with the axis of the taper pipe 4.
Further, the cross-sectional area of the taper pipe 4 gradually decreases from the direction close to the pilot pipe 3 to the direction away from the pilot pipe 3.
Further, still fixedly on leading 3 inside walls of pipe being equipped with separation blade 1, strong magnet 2 passes through separation blade 1 and fixedly sets up on leading 3 inside walls of pipe.
During the use, will lead in the centralizer sends into the drilling, lead and put the disconnected drilling rod position that falls under the pipe 3, lead the pipe 3 and restrict the drilling rod at leading positive pole middle part position, hold the drilling rod through leading strong magnet 2 on the pipe 3, when the top of drilling rod entered into the taper pipe 4 inside, lean on the die in the taper pipe 4 to carry out the tapping to the drilling rod, make drilling rod and leading the centralizer accomplish fixedly, pull out the centralizer through the hoist engine to take out the drilling rod.
The utility model provides a design is fixed the drill pipe in the certain limit through leading positive pipe, holds the drilling rod through leading strong magnet on the positive pipe, utilizes the die of taper pipe inside to carry out the tapping to the drilling rod, couples together the drilling rod with leading positive ware fixed connection, takes out the drilling rod, effectively solves the problem that the drilling rod can't take out, has avoided the useless condition that falls of well.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
