Abstract

The invention relates to a ground and downhole two-way wireless communication system, device and method for a producing well. The system comprises lifting equipment which is disposed on the ground and is connected with a first communication module; and a connecting piece which is arranged downhole and is connected with the lifting equipment and a second communication module, wherein the first communication module is configured to transmit information / data / signals in such a way that the lifting equipment changes the motion state of the connecting piece, and obtain the information / data / signals by detecting the load change of the lifting equipment; the second communication module is configured to transmit information / data / signals by changing the load of the lifting equipment, and obtain the information / data / signals by detecting the motion state of the connecting piece. By means of the arrangement mode, signals do not need to be transmitted through downhole fluid or a downhole pipe, so that the defects of downhole transmission attenuation and large interference are overcome, and the reliability and stability of ground and downhole two-way wireless communication are improved.

Description

technical field [0001] The invention relates to the technical field of underground energy exploitation, in particular to a ground-underground two-way wireless communication system, device and method for oil production wells, coal mine wells, natural gas wells and other similar scenarios. The present invention can also be applied to underground communication application scenarios. Background technique [0002] Due to the multi-layer and heterogeneity characteristics of domestic oil fields, in order to ensure that the oil fields can be fully exploited, the data monitoring and information transmission of the oil production wells are very important. Specifically, the information transmission between the downhole and the surface is an important research project in the fields of logging, drilling and oil production. It is important for the exploration and development of oil resources, the geological structure of proven oil layers, the status of test oil wells and the maintenance o...
