A method for monitoring the seismic source in high-efficiency acquisition

Abstract

The present invention is a seismic source monitoring method for seismic exploration technology. A base station and a host computer are arranged in the seismic team camp, an antenna is set up, a digital transmission station is installed at the seismic source and the base station, and communication between the seismic source and the base is established; the real-time position of the seismic source is obtained through the digital transmission station. , scanning parameters, and attributes are sent back to the base, and the main system of the base performs production statistics and efficiency statistics on multiple vibrator vehicles. The invention can meet the requirements of high-efficiency acquisition on site, effectively monitor the simultaneous construction of multiple seismic sources in the field in real time, and the control center can monitor the position of multiple seismic sources, GPS status, output, distortion, and phase information of each earthquake in real time, improving efficiency and quality , The high-quality rate of blasting has reached more than 99%, and the average daily efficiency has reached more than 5,200 shots.

Description

technical field [0001] The invention relates to seismic exploration technology, and is a seismic source monitoring method in high-efficiency acquisition. Background technique [0002] With the development of seismic exploration acquisition technology, high-efficiency acquisition technology is more and more widely used. In the existing high-efficiency seismic exploration acquisition technology, due to the increase in the number of vibrators involved in the operation, the monitoring of the source has always been a weak link. , in conventional projects using seismic instruments for acquisition, the instrument is generally used for real-time monitoring and production management of the seismic source; for example, the currently commonly used Sercel408, Sercel428 series, etc., can monitor the state and position of the seismic source, but if There are too many seismic sources, and a free and independent scanning method is adopted, that is, the seismic source is not controlled by th...

Under such circumstances, these seismic instruments are helpless and cannot monitor the seismic source
