Abstract
The utility model discloses a natural gas opens and adopts drilling rod, including the drilling rod body, the drilling rod body is the cylinder structure, and its front end is equipped with the drill bit, the exhaust hole has been seted up at drilling rod body middle part, the inside exhaust passage who communicates with the exhaust hole of seting up of drilling rod body, the inside end draw-in groove of seting up with the exhaust passage intercommunication of drilling rod body tail end. This natural gas is opened and is adopted the drilling rod, simple structure, and reasonable in design can satisfy the probing work of natural gas, is worth wideling popularize.
Description
Technical Field
The utility model belongs to the technical field of the drilling rod, concretely relates to drilling rod is adopted in natural gas exploitation.
Background
The drill rod is a steel pipe with threads at the tail part and is used for connecting surface equipment of a drilling machine and drilling and grinding equipment or a bottom hole device at the bottom end of a drilled well. The purpose of the drill pipe is to carry drilling mud to the drill bit and, together with the drill bit, raise, lower or rotate the bottom hole assembly. The drill pipe must be able to withstand large internal and external pressures, twists, bends and vibrations. In the process of oil and gas exploitation and extraction, the drill pipe can be used for multiple times. The drill rods are divided into a kelly, a drill rod and a weighted drill rod. The connection sequence is square drill rod (1), drill rod (n, determined by well depth), weighted drill rod (n, determined by drill tool combination design).
Because the natural gas is gaseous resources, and many storages are below the earth's surface in addition, along with the continuous deepening of drilling rod, the natural gas can constantly spill over, slowly gathers inside drilling, makes inside atmospheric pressure increase, if not in time with the natural gas discharge, can make the pressure grow that the drilling rod bore, dangerous accidents such as explosion can take place even, therefore we need a natural gas to open and adopt the drilling rod to solve above-mentioned problem, satisfies people's demand.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drilling rod is adopted in natural gas exploitation to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a drilling rod is adopted in natural gas division, includes the drilling rod body, the drilling rod body is the cylinder structure, and its front end is equipped with the drill bit, the exhaust hole has been seted up at drilling rod body middle part, the inside exhaust passage who communicates with the exhaust hole of seting up of drilling rod body, the inside end draw-in groove of seting up with exhaust passage intercommunication of drilling rod body tail end.
Preferably, the length of the drill rod body is 5978 mm. The diameter was 74 mm.
Preferably, two exhaust holes are symmetrically arranged on the drill rod body 1.
Preferably, the end clamping groove is a cylindrical cavity, the length of the end clamping groove is 86mm, and the effective buckling length is 83 mm.
The utility model discloses a technological effect and advantage: this drilling rod is adopted in natural gas division, simple structure, reasonable in design, exhaust hole and the exhaust passage who corresponds have been seted up to the drilling rod body for the natural gas can be discharged smoothly, reduces the gathering of natural gas, has improved probing efficiency, has reduced the probing risk.
Drawings
Fig. 1 is a schematic view of the main structure of the present invention.
In the figure: 1. a drill rod body; 2. a drill bit; 3. an exhaust hole; 4. an exhaust passage; 5. an end clamping groove.
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.
The utility model provides a drilling rod is adopted in natural gas division as shown in figure 1, including drilling rod body 1, drilling rod body 1 is the cylinder structure, and its front end is equipped with drill bit 2, exhaust hole 3 has been seted up at drilling rod body 1 middle part, drilling rod body 1 is inside to be seted up with the exhaust passage 4 of exhaust hole 3 intercommunication, drilling rod body 1 tail end is inside to be seted up with the end draw-in groove 5 of exhaust passage 4 intercommunication.
Specifically, the drill rod body 1 is 5978mm long. The diameter was 74 mm.
Specifically, two exhaust holes 3 are symmetrically arranged on the drill rod body 1.
Specifically, the end clamping groove 5 is a cylindrical cavity, the length of the end clamping groove is 86mm, and the effective buckling length is 83 mm.
The working principle is as follows: this natural gas is opened and is adopted the drilling rod, when using, makes interconnect between drilling rod body 1 through end draw-in groove 5, wherein exhaust hole 3 and the setting that corresponds exhaust passage 4 make the natural gas that overflows in the drilling hole in time discharge.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
