Harness routing structure of generator in drilling tool

Abstract

The invention discloses a wiring harness wiring structure of a generator in a drilling tool, which includes a drill collar, in which a rotary connector, an impeller mechanism, a power generation mechanism and a generator control mechanism are sequentially arranged, and a power generation mechanism is arranged outside the power generation mechanism To protect the outer cylinder, a first wiring trough is provided on the outer wall of the generator mechanism, one end of the first wiring trough extends to the impeller mechanism, and the other end extends to the generator control mechanism; one end of the impeller mechanism is provided with a rotary connector to connect The other end of the multi-core connector is provided with a wiring hole connected to the first wiring trough, and the outer wall of the impeller mechanism is provided with a second wiring trough. The groove and the impeller mechanism protect the inner wall of the outer cylinder to form a second wire harness warehouse, one end of the second wire routing groove extends to the multi-core connector, and the other end extends to the wire routing hole. The invention can effectively protect the wires and communication lines, effectively prevent abrasion, improve the durability, and ensure the normal operation of the drilling tool.

Description

technical field [0001] The invention relates to a wiring harness routing structure of a generator in a drilling tool, and belongs to the technical field of rotary steerable drilling. Background technique [0002] Rotary steerable technology is a cutting-edge automated drilling technology, which is mainly composed of downhole rotary steerable drilling tools, ground monitoring system and two-way communication technology that links the above two parts together. There are many electronic instruments in the rotary steerable drilling tool. In addition to the ground power supply, a generator needs to be installed in the downhole drilling tool. The generator supplies power and communicates with the upper and lower instruments. [0003] In the prior art, the communication and power supply of the generator need to be transmitted by wire. The prior art method is to install a hollow tube in the central axis of the generator, so that the electric wire and the communication line pass thro...

Problems solved by technology

[0003] In the prior art, the communication and power supply of the generator need to be transmitted by wire. The prior art method is to install a hollow tube in the central axis of the generator, so that the electric wire and the communication line pass through the hollow tube, but due to The rotation speed of the generator rotor is very high, and the hollow tube in the central shaft is prone to resonance. On the one hand, because the hollow tube is very thin, the internal wires and communication lines will rub against the inner wall of the hollow tube when it vibrates, and the wires will be worn out. On the other hand, the hollow tube will also rub against the central shaft of the generator, causing the hollow tube wall to be worn out, causing the leakage of electric wires and communication lines, and directly rubbing against the central shaft of the generator to cause damage. Whether the electric wire or the communication line is damaged, it will Affect the normal work of the rotary steerable drilling tool, because the rotary steerable drilling tool works underground and cannot be repaired, even if it is salvaged from the ground, the maintenance work will be very complicated and difficult, resulting in significant economic losses
