Problems solved by technology
Due to the lack of network conditions in most construction areas, the quality control of vibroseis has completely lost its real-time performance, and it is impossible to discover and control the quality-affecting factors in production in time, thus reducing the convenience of vibroseis monitoring, and at the same time giving vibroseis The monitoring of the

specific example
[0050] To give a specific example, such as figure 2 as shown, figure 2 It is a structural schematic diagram of an example of a vibroseis monitoring device provided by an embodiment of the present invention. In the prior art, during the construction of the node system, if the vibrator enters the autonomous excitation mode, since there is no traditional seismic instrument ( figure 2 Marked in ), due to the failure of the data path to send control instructions to the seismic source and receive the vibration state through the data radio station, the excitation state of the seismic source cannot be transmitted through the radio station in time, so it can only be transmitted to the navigation system, which is stored by the navigation system. When the navigation data is recovered, it is recovered and analyzed together, resulting in a blank period of quality monitoring in production. However, the vibroseis monitoring device provided by the embodiment of the present invention can ...

The invention provides a vibroseis monitoring method and device and a vibroseis monitoring system. The device comprises an interface module which is used for obtaining the excitation quality data of avibroseis from a vibroseis box body in real time, and obtaining the operation state data of the vibroseis from a vibroseis controller; a main control module which is used for selecting to transmit vibroseis excitation quality data or vibroseis operation state data to the LoRa module according to the received data switching instruction; and a LoRa module which is used for sending the received vibroseis excitation quality data or vibroseis operation state data to the vibroseis monitoring system by using a LoRa technology. According to the invention, the LoRa technology is adopted to carry out real-time transmission on the vibroseis excitation quality data and the vibroseis operation state data; compared with the prior art, the problem that data stored in the local vibroseis is difficult totransmit is solved, the vibroseis monitoring problem under the condition of no network is solved, the blank period of vibroseis monitoring is avoided, and the monitoring convenience of the vibroseis is improved.
Description
technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to a vibroseis monitoring method, device and vibrator monitoring system. Background technique [0002] With the gradual application of nodal instruments in exploration projects, vibroseis autonomously stimulating production has attracted more and more attention from major geophysical prospecting companies. The self-excitation mode of node instruments plus vibrator means that the production efficiency of geophysical prospecting projects has been improved again, and the traditional instrument carts have gradually faded out. [0003] In the prior art, when the vibrator enters the autonomous excitation mode, because there is no control of the instrument, the excitation state of the vibrator can only be transmitted to the navigation system, and stored by the navigation system, and it will be recovered and analyzed when the navigation data is recovered. Thereby causing a bl...
