Abstract
The invention relates to a drilling tool with taper pipe thread connection. The drilling tool comprises a first drilling tool (1) and a second drilling tool (2). The first drilling tool (1) and the second drilling tool (2) share the same structure. Female thread is arranged on the upper end of each drilling tool; and male thread is arranged on the lower end of each drilling tool. The male thread on the lower end of the second drilling tool (2) is connected with the female thread on the upper end of the first drilling tool (1); and the surface hardness values of the male thread and the female thread have the difference of above HRC10. The drilling tool has a simple structure. As the surface hardness value of the male thread is different from that of the female thread, no adhesion or buckling damage occurs when the male thread and the female thread are connected, thereby prolonging the service life of the drilling tool, reducing the economic loss, and improving the working efficiency. The drilling tool saves the manufacturing cost of the drilling industry, improves the satisfaction degree of the customers, and reduces the after service cost.
Description
Technical field
The invention belongs to drilling tool, be specifically related to the drilling tool that a kind of taper pipe thread connects.
Background technology
For a long time, domestic all produce the producer of drilling tools, the product that the taper pipe thread of same material connects all has the phenomenon of screw thread thread gluing to take place, application life of drilling tool has been shortened in the generation of this accident, has caused enormous economic loss for domestic probing industry.Also do not obtain breakthrough solution up till now, especially more outstanding at oil, natural gas, probing industry.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, the drilling tool that provides a kind of taper pipe thread of the thread gluing accident that a kind of screw thread that solves equivalent material taken place when connecting to connect.
Technical scheme of the present invention: the drilling tool that a kind of taper pipe thread connects, it comprises first drilling tool 1, second drilling tool 2, first drilling tool 1 is identical with the structure of second drilling tool 2, their upper end is provided with box thread, the lower end is provided with male thread, and the male thread of second drilling tool, 2 lower ends connects with the box thread of first drilling tool, 1 upper end, and the case hardness value of male thread and box thread differs more than the HRC10.The case hardness value of male thread and box thread differs HRC10～40.The present invention adopt quench, ooze, technology such as plating makes.
The present invention compared with prior art has following beneficial effect: the present invention is simple in structure, after male thread and box thread case hardness differ, sticking connection will can not take place when it connects and decrease the phenomenon of detaining, thereby prolong the application life of drilling tool, reduce economic loss, increase work efficiency.Save the cost of production of probing industry, improve user's satisfaction, reduce after-sale service cost.
