High-performance tool joint for transmitting electric power and relevant signals

Abstract

The invention relates to a high-performance tool joint for transmitting electric power and relevant signals. The high-performance tool joint consists of an internally threaded part and an externally threaded part, wherein the internally threaded part comprises a first external circular bead surface, a first cylindrical hole, an internal thread, a conical hole, a second cylindrical hole and an internal circular bead surface; the first external circular bead surface is positioned at the top end of the internally threaded part; the first cylindrical hole, the internal thread, the conical hole, the second cylindrical hole and the internal circular bead surface are arranged on the inner wall of the internally threaded part sequentially from the first external circular bead surface backward; the internal circular bead surface is annularly provided with a first signal transmission channel; one side of the internal circular bead surface is through provided with a first joint pipe transmission channel communicated with the first signal transmission channel; the externally threaded part comprises a second external circular bead surface, a first cylindrical surface, an external thread, a second cylindrical surface and a third external circular bead surface; the second external circular bead surface is positioned at the top end of the externally threaded part; the first cylindrical surface, the external thread, the second cylindrical surface and the third external circular bead surface are arranged on the outer wall of the externally threaded part sequentially from the second external circular bead surface backward; the second external circular bead surface is annularly provided with a second signal transmission channel; and one side of the internal circular bead surface is axially through provided with a second joint pipe transmission channel communicated with the second signal transmission channel. The high-performance tool joint solves the technical problems.

Description

technical field [0001] The invention relates to a tool joint for oil and natural gas development, in particular to a high-performance tool joint for transmitting electric power and related signals. Background technique [0002] With the exploitation of oil and gas fields around the world, it is increasingly required to realize efficient and intelligent control of the drilling and production process, so as to realize the full exploitation of resources. However, the existing technology is generally unable to effectively feedback control the drilling equipment, especially the drill string under the ground, resulting in the inability to timely and accurately obtain the conditions below the ground during drilling and production, which is also the main reason for the low efficiency of the production process. one of the reasons. If the information exchange and real-time control between the surface and the equipment below the surface can be established in the exploitation of oil an...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-performance tool joint for transmitting power and related signals, which mainly solves the technical problems that the existing product structure is relatively complicated and is not easy for actual production and use, and it helps to improve the working conditions. The degree of intelligence, and absorbing the advantages of mature traditional joint technology and easy processing, the use of internal threaded parts and external threaded parts, the setting of double shoulders can play a good anti-torsion performance and prevent partial failure of the joint; The design of this joint can significantly reduce the stress level and stress concentration of the joint structure, effectively reduce the probability of fatigue damage, its torsional performance is greatly improved, and it can realize the transmission of power and related signals, and realize the ground The effective feedback of underground equipment and underground equipment has achieved the purpose of controlling the mining process according to requirements, and greatly improved production efficiency
