Description
Technical Field
The utility model belongs to the technical field of the connector, concretely relates to connector for deep sea drilling rod.
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).
Due to the limited manufacturing process and transportation conditions, a drilling well can only be formed by connecting a plurality of drill rods through a connector, the traditional connector is insufficient in corrosivity and wear resistance, particularly when drilling operation is carried out in the sea, the service life of the connector is shortened due to seawater corrosion and abrasion of hard substances such as rocks, the drill rods and the connector are difficult to detach after the drilling operation is completed, and great troubles are brought to follow-up work, so that the problem is solved by the connector for the deep sea drill rod, and the requirements of people are met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a deep sea is connector for drilling rod to solve the problem that proposes in 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 connector for deep sea drilling rod, includes the connector body, connector body one end is equipped with the bayonet joint, and the inside little inserting groove of having seted up of bayonet joint, the inside big inserting groove of having seted up of connector body other end, the round pin groove has been seted up on the connector body.
Preferably, the plug is a cylindrical structure, the length of the plug is 120mm, and the diameter of the cross section of the plug is 110 mm.
Preferably, the small insertion groove is a cylindrical groove with a conical front end, the length of the small insertion groove is 55mm, and the diameter of the cross section of the small insertion groove is 16 mm.
Preferably, the length of the pin slot is 218 mm.
Preferably, the connector body is of a cylindrical structure, and the total length is 1500 mm.
Preferably, the front end of the large insertion groove is of a conical structure.
Preferably, the connector body is made of Q345 type wear-resistant stainless steel material, and the surface of the connector body is plated with chromium as the wear-resistant material.
The utility model discloses a technological effect and advantage: this connector for deep sea drilling rod, simple structure, the assembly is reasonable, what how make the connection between the drilling rod more firm stable of many grafting works, and Q345 is as connector preparation material for the compressive capacity and the corrosion resisting capability of junction are stronger, and chromium plating makes the wearability of connector strengthen greatly, has improved the life of connector.
Drawings
Fig. 1 is a schematic view of the main structure of the present invention.
In the figure: 1. a connector body; 2. a plug-in connector; 3. a small insertion groove; 4. a large insertion groove; 5. a pin slot.
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 connector for deep sea drilling rod as shown in figure 1, including connector body 1, 1 one end of connector body is equipped with bayonet joint 2, and small insertion groove 3 has been seted up to bayonet joint 2 inside, big insertion groove 4 has been seted up to the connector body 1 other end inside, the round pin groove 5 has been seted up on connector body 1.
Specifically, the plug 2 is a cylindrical structure, the length of which is 120mm, and the diameter of the cross section of which is 110 mm.
Specifically, the small insertion groove 3 is a cylindrical groove with a tapered front end, the length of the groove is 55mm, and the cross-sectional diameter of the groove is 16 mm.
In particular, the length of the pin slot 5 is 218 mm.
Specifically, the connector body 1 is a cylindrical structure, and the total length is 1500 mm.
Specifically, the front end of the large insertion groove 4 is of a conical structure.
Specifically, the connector body is made of Q345 type wear-resistant stainless steel material, and the surface of the connector body is plated with chromium as a wear-resistant material.
The working principle is as follows: this connector for deep sea drilling rod, when using, in corresponding insertion slot and plug through bayonet joint 2 and big inserting groove 4, in little inserting groove 3 corresponds the little plug of inserting simultaneously, a plurality of grafting combinations make drilling rod and connector body 1's grafting cooperation more firm stable, its intensity and corrosion resistance are higher by Q345 material system to connector body 1, and connector body 1 has plated the one deck chromium material, and the wearability is higher.
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.
