Abstract
The utility model relates to a kind of naked eye specific drilling tools, the drilling tool includes female connector, pin end and connector, the female connector is connect by the connector with the pin end, box thread is provided on the inner wall of the female connector, male thread is provided on the outer wall of the pin end, the male thread matches with box thread, first shoulder is provided on the female connector, the second shoulder is provided on the pin end, solving existing small size drilling tool, inboard wall of tube body pressure loss is excessive in use, discharge capacity does not reach requirement, and takes the problem of husky ability difference.
Description
Technical field
The utility model relates to drilling tool technical field, especially a kind of naked eye specific drilling tool.
Background technique
Previous client to the drilling tool demand of small size huge discharge and few, but in recent years due to the raising of drilling technology and
The appearance of some special operation conditions, the requirement to small size drilling tool are also being continuously improved.The discharge capacity of small size drilling tool is not achieved at present
It is required that.
Utility model content
The purpose of this utility model is to provide for a kind of naked eye specific drilling tool.
The technical solution of the utility model is: a kind of naked eye specific drilling tool, including female connector, pin end and connector, institute
It states female connector to connect by the connector with the pin end, box thread, the public affairs is provided on the inner wall of the female connector
Male thread is provided on the outer wall of connector, the male thread matches with box thread, it is provided with first shoulder on the female connector,
The second shoulder is provided on the pin end, the first shoulder matches with the second shoulder.
A kind of above-mentioned naked eye specific drilling tool, the female connector and the connector weld, the pin end and the company
Fitting welding.
The beneficial effects of the utility model are: solving existing small size drilling tool inboard wall of tube body pressure loss in use
Excessive, discharge capacity does not reach requirement, and takes the problem of husky ability difference.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of naked eye specific drilling tool of the embodiment of the present application.
In figure: 1- female connector, 11- first shoulder, 2- pin end, the second shoulder of 21-, 3- connector.
Specific embodiment
In order to more clearly state the utility model, the utility model is further described with reference to the accompanying drawing.
Refering to fig. 1, a kind of naked eye specific drilling tool, the drilling tool include female connector 1, pin end 2 and connector 3, the mother
Connector 1 is connect by the connector 3 with the pin end 2, and box thread, the public affairs are provided on the inner wall of the female connector 1
Male thread is provided on the outer wall of connector 2, the male thread matches with box thread, is provided with First on the female connector 1
Shoulder 11 is provided with the second shoulder 21 on the pin end 2.
A kind of above-mentioned naked eye specific drilling tool, the female connector 1 are welded with the connector 3, the pin end 2 with it is described
Connector 3 welds.
It is sealed using sealing shoulder, reduces connector outer diameter size, increase the annular space between connector and casing.
The drilling tool of the embodiment of the present application is one kind 3 1/2 " nonstandard drilling rod, make in drilling process mud displacement it is bigger,
Take that husky ability is stronger, connector outer diameter is smaller, annular space is bigger, tube body inner tubal wall pressure loss is smaller, and drill pressure is more sufficient, sealing
Property is more preferable, is more suitable for present operation, brings more convenience to drilling tool operation, has been greatly reduced the cost of drilling well.
Increasingly thinner with drilling liner, in maintenance and secondary probing, the miniature requirement of drilling tool outer diameter is increasingly
Strongly, while in order to solve in a limited space, the reasonable circulation volume for distributing inside and outside tubing string reduces the pressure of pump group,
Exploitation devises 3 1/2 special drilling tools, and connector outer diameter can achieve 100mm, the design parameter such as following figure:
| Outer tube diameter | Tube body tensile strength | Tube body torsional strength | Screw thread specification | Connector outer diameter | Connector internal diameter | Connector tensile strength | Connector torsional strength |
| 88.9 | 169 | 35213 | PD29 | 100 | 50.8 | 221.6 | 20615 |
The control of upsetting quality: steel pipe upsetting is exactly the end by steel pipe after local heating, makes its length by squeezing
Shorten, the increased technique of wall thickness, its purpose is to improve the intensity of steel pipe junction.Drilling rod is integrally burning hot using quenching add-back
Treatment process realizes its service performance.Drill rod materials use low-alloy structural steel.End and weld seam heating all use electromagnetism
Induction heating.
The embodiment created above to the utility model is described in detail, but the content is only the utility model wound
The preferred embodiment made, should not be considered as limiting the scope of the present invention.It is all to create range according to the utility model
Made all the changes and improvements etc., shall still fall within the scope of this patent.
