Underground bidirectional communication device

Abstract

The invention relates to the underground communication device technology field and discloses a underground bidirectional communication device. The device comprises a non-magnetic short section, an electronic short section, a pulse generator, a mud turbine generator and a pin connecting sleeve. An inner side of a lower portion of the non-magnetic short section and an outer side of an upper portion of the electronic short section are sealed and fixedly installed together. An outer sleeve is installed on the outer side of the upper portion of the electronic short section in a sealing mode. The structure is reasonable and compact and usage is convenient. During a usage process, under the condition that a traditional channel mode is not changed, a underground signal can be uploaded to a well and a well signal is downloaded to the underground, bidirectional communication of signal transmission is realized and disconnection prevention assembly setting is realized too. When the non-magnetic short section and the electronic short section are connected, a cable fracture phenomenon of a cable between a second line passing channel and a third line passing channel can be prevented, and the device can be maintained to carry out bidirectional communication so that the device can be widely applied to bidirectional communication of oil underground mechanical and electrical equipment.

Description

technical field [0001] The invention relates to the technical field of underground communication devices, and relates to an underground two-way communication device. Background technique [0002] In the development process of oil and gas wells, various electromechanical devices are often used at the bottom of the well to complete related communication tasks, such as directional measurement, data storage, and local control. For such electromechanical products, circuit modules ( Such as voltage stabilizing circuit, rectifying circuit, pulse driving circuit and downlink signal transceiver circuit, etc.) are fixed inside the structure, and the structure itself needs to be used to transmit power, and the circuit part needs to be well sealed, connected and assembled, and finally realize data transmission. During the assembly process of the tool, the cable at the tool connection end is prone to damage or even breakage, especially when the tool is connected with a screw. The damage...
