Communication line routing device of subsurface equipment

Abstract

The invention relates to a communication line routing device of subsurface equipment, comprising a framework of a logger, a lower joint and a bearing pipe, wherein the lower end of the framework is connected with the lower joint; the two ends of the bearing pipe are respectively communicated with the inner part of the upper end part and the inner part of the lower joint; the bearing pipe is embedded in a groove on the outer surface of the framework; the lower joint and the framework are connected by a screw sleeve between the lower joint and the framework; the outer part of the screw sleeve is provided with threads matched with internal threads of the lower end of the framework; the screw sleeve pushes against the lower joint by a combined semi-ring-shaped stopping block embedded into the outer surface of the lower joint; a guide structure parallel to the axial direction is arranged between the lower joint and the lower end of the framework; and the connecting part of the bearing pipe and the lower joint is axially parallel to the lower joint. In the communication line routing device of the subsurface equipment, the installation of the bearing pipe is simple and convenient, the middle of the bearing pipe does need switching joints, the structure is simplified, the occupied space is little, only the liner movement is needed when the bearing pipe is connected with the lower joint, and the installation of the bearing pipe can be finished while installing the lower joint.

Description

technical field [0001] The invention relates to the technical field of petroleum downhole instruments, in particular to a downhole instrument through-wire routing device. Background technique [0002] The downhole instrument has limited space, compact structure, and harsh working environment. The problem of the wiring of the through-line has always troubled the structural engineers in this field. At present, in most downhole instruments, the wiring of the through-line is generally realized in the following four ways: [0003] 1. The center tube, the use of the center tube has great restrictions on the routing of the center tube, and the center tube cannot be installed in many structures; [0004] 2. The sealing plug is transferred, and the wiring with the sealing plug is easy to cause insulation problems, and there is not enough space in the instrument to install too many sealing plugs; [0005] 3. External pressure-bearing hard pipe, because the shape of the pressure-beari...
