One-excitation multi-receiver seismic data acquisition system

Abstract

The invention discloses a one-excitation multi-receiver seismic data acquisition system. The one-excitation multi-receiver seismic data acquisition system comprises an earthquake focus, a wired acquisition device, a wireless acquisition device, a control center, a first GPS receiver and a second GPS receiver; first data are obtained by the wired acquisition device; second data are obtained by thewireless acquisition device; the control center is connected with the earthquake focus; the control center is connected with the wired acquisition device; the first GPS receiver is connected with thecontrol center; and the second GPS receiver is connected with the wireless acquisition device. According to the one-excitation multi-receiver seismic data acquisition system, the problems that layoutof a single set of acquisition device in the field is inconvenient, and the wired acquisition device is difficult to lay out in special places such as urban areas, mountain areas, jungles, and farmland are effectively solved, arrangement is expanded, and the construction efficiency is improved. Synchronous acquisition in real time can be achieved, and the data obtained by the wired collecting device and the wireless collecting device are consistent in data format.

Description

technical field [0001] The present invention generally relates to the field of seismic wave exploration, and more specifically relates to a single-stimulation multiple-shot seismic data acquisition system and method for the exploration of underground resources such as cities and mountains. Background technique [0002] At present, underground resource exploration is gradually changing from simple to complex, from data collection of hundreds of channels to data collection of hundreds of thousands of channels. Seismic acquisition is investing more and more equipment, the coverage frequency is getting higher and higher, and the bins are getting smaller and smaller, and it is developing in the direction of high density, wide azimuth, and wide frequency. [0003] In the case of complex surface conditions, such as cities, mountains, etc., especially in urban areas, the layout of existing wired acquisition equipment will be subject to various obstacles, and at the same time, it wil...
