Abstract

The invention relates to a hybrid remote measurement seismic prospecting method. Most basic data acquisition link are constructed by use of data conversion devices and acquisition units, and data transmission on the links employs a wired communication mode. Host computers and data exchange devices form independent network measurement units, and high-speed data communication between the host computers and the data conversion devices is realized by use of local area networks in the network measurement units. The host computers and a master control computer form networks by use of a 4G technology, and the master control computer can realize control of the acquisition units and real-time recovery of acquisition data. According to the invention, the hybrid remote measurement seismic prospecting method is formed by making full use of advantages of such communication technologies as the 4G network technology, a local area network technology and a wired communication technology in the acquisition links, such that the working efficiency is improved and the field construction cost is reduced under the condition that the real-time monitoring requirement for seismic prospecting data is satisfied.

Description

technical field [0001] The invention relates to a seismic prospecting method based on traditional geophysical methods, in particular to a method for realizing the control of seismic acquisition units and the monitoring of data under complex terrain and multi-channel (ten thousand channels) conditions. Background technique: [0002] Seismic prospecting method is the main method of mineral resources exploration. With the development of science and technology, the ability of this method to solve complex mineral geological problems is continuously enhanced. Seismic exploration instruments are the key equipment in seismic exploration methods. In the past 60 years, seismic exploration instruments have gone through five development stages: light spot recording seismograph, analog tape recording seismograph, digital seismograph, telemetry seismograph, and all-digital telemetry seismograph. The concept of its design has realized the transition from centralized to distributed, from wi...
