Electric connector

Abstract

The invention discloses an electric connector which comprises a male plug and a female socket, wherein the male plug comprises a battery cell bar, a battery cell bar protective casing, a pressure-resistant housing, first reset springs, a battery cell bar positioning sleeve and a housing connector; the female socket comprises an electric socket, an electric socket filling bar, a pressure-resistant housing, a sleeve, a sleeve connector, a pressing block, second reset springs, springs and a housing connector; the battery cell bar comprises a first framework, first conducting rings and first cable cores; and the electric socket comprises a second framework, second conducting rings and second cable cores. According to the electric connector, mechanical connection is realized through matching of a drill tool male connector and a drill tool female connector, information channel connection is realized through contacted matching of the first conducting rings and the second conducting rings, and connection of short sections of downhole tools is completed in a working site, so that the electric connector is fast, convenient and reliable in connection, and can prevent the first reset springs and the second reset springs from interfering cables during compression and reset; and meanwhile, rigidity compensation is achieved through third springs, so that the battery cell bar and the electric socket of the electric connector are protected from being damaged.

Description

technical field [0001] The invention relates to an oil drilling equipment, in particular to an electric connector used for a coiled tubing downhole electric tool. Background technique [0002] With the continuous development of coiled tubing related technologies, coiled tubing and related equipment have been increasingly used in drilling and logging of horizontal wells and directional wells. Since coiled tubing is a continuous section of thin-walled circular tube, compared with conventional Rod, in the process of operation, does not need to connect joints, and constitutes a continuous channel connecting ground equipment and sub-sections of downhole tools. Therefore, through the penetration of cables in coiled tubing to build downhole power and signal channels, electric drilling and logging work It has higher feasibility and better advantages than electric drilling and logging under conventional drill pipe. In this way, the established downhole power and signal channels can ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the complex and difficult operation of connecting two downhole tool nipples with different functions in the prior art, and the need to coil the cable in the joint through the non-rotary joint connection, which is not suitable for small diameters. For the above-mentioned shortcomings of large cable connections, an electrical connector is provided, which can more quickly and conveniently connect the sub-joints of downhole tools at the operation site.
