Problems solved by technology

[0004] The inventors have found that at least the following problems exist in the prior art: when monitoring the monitoring index of the vibrator in the prior art, only the current instantaneous parameter value of the monitoring index can be monitored. Time-continuous monitoring indicators such as the constrained position formed by the time interval and spatial distance between shots, the combined center position of multiple vibrators, and the downtime of vibrators cannot be obtained by the methods used in the prior art. The value of the monitoring index may lead to an incomplete monitoring of the vibrator

Abstract

The embodiment of the invention discloses a monitoring method and system for a controllable hypocenter. The method comprises the steps that aiming at multiple controllable hypocenters in an aim work area, working state information files of each shake frequency of the controllable hypocenters are obtained; according to the working state information files of each shake frequency of the controllable hypocenters, parameter values of a preset monitoring index are obtained; according to threshold values and obtained parameter values of the preset monitoring index, the controllable hypocenters are monitored; the preset monitoring index comprises at least one of the followings: integrity degree of the working state information files, status code, at least one kind of properties of the controllable hypocenters, constraint location, combination center position, and idle time. Overall monitoring for the work state of the controllable hypocenters is achieved.

Description

technical field [0001] The present application relates to the technical field of petroleum exploration, in particular to a monitoring method and system for a vibroseis. Background technique [0002] A vibrator is a source that can pre-control the scanning frequency range and vibration duration. In the process of petroleum seismic exploration and seismic data acquisition, the working state of the vibrator is the key technical index of the seismic data acquisition system, which may directly affect the quality of the acquired seismic data. Therefore, real-time and accurate monitoring of the working state of the vibroseis is an urgent problem to be solved. [0003] Currently, the commonly used vibroseis monitoring method is mainly to send the working status information of all vibrators on the target work area to the control equipment. The control equipment has its own monitoring device. Monitoring indicators for sources perform monitoring operations. The control equipment can...
