Carbon fiber submersible conducting rod

Abstract

The present invention relates to a carbon fiber submersible conducting rod. The carbon fiber submersible conducting rod comprises a rod body, a socket module and a plug module, the socket module is fixedly installed at the upper end of the rod body, the plug module is fixedly installed at the lower end of the rod body, a plurality of conducting rods are connected in series and inserted in order through the plug modules and the socket modules, the socket module comprises a connection hoop, a copper insertion hole, a fixed table shoulder and an upper-end female socket, the end portion of the upper-end female socket is provided with a copper insertion hole, the connection hoop is installed on the upper-end female socket, the connection hoop is internally provided with internal threads; the connection position of the connection hoop and the upper-end female socket is provided with a first seal lead pad, and the fixed table shoulder arranged in the upper-end female socket in the connectionhoop is used to press the first seal lead pad; and the fixed table shoulder is rotationally connected with the connection hoop at the internal portion of the connection hoop. The carbon fiber submersible conducting rod achieves conductive laying in the oil tube, the conducting rod employs a magnesia ceramics sintering insulation mode, the carbon fiber composite materials are taken as the housing of the conducting rod, and therefore, the carbon fiber submersible conducting rod is suitable for complex bad working conditions such as the high temperature, the high pressure and corrosion of the oilwell, and is long in service life.

Description

technical field [0001] The invention relates to an oil well conductive rod, in particular to a carbon fiber submersible oil conductive rod. Background technique [0002] At present, the submersible pumps used in oil wells all use submersible cables to power the submersible motors. Most of the submersible cables are armored cables with multi-layer insulation. The outermost layer is made of stainless steel armor, and the withstand voltage level is 3000 / 6000V. Temperature resistance grade 90 / 120℃. During the downhole process, the cable is bound on the outer wall of the tubing by stainless steel clips. As the tubing goes downhole, the cable is drawn out from the wellhead cable hole of the electric pump at the wellhead. [0003] During the pump operation in the actual oil well operation, the tubing collar and the inner wall of the oil well casing are easy to collide. If the collision part is the cable binding, the cable is easily damaged by the collision, resulting in an insulat...

Problems solved by technology

[0004] Aiming at the problems in the prior art that the submersible pump and the submersible cable are used in the production and application of the oil well production lifting system, the workload of binding the cable is large, the accident of foreign matter falling into the well is easy to be caused, and the service life of the submersible cable is low. The problem to be solved by the present invention is to provide A carbon fiber submersible conductive rod adapted to the complex and harsh working conditions of oil wells and with a long service life
