Problems solved by technology

It can be seen that the test workload of the digital package to be tested is heavy, and the test content is also many and complicated. It is obviously difficult to complete through manual testing.
[0009] However, in the existing seismic data acquisition system, there is no technical solution that can automatically test the digital package, which obviously does not meet the requirements of the growing seismic data application technology

Abstract

The invention discloses a system and method for realizing testing of a geophysical exploration digital packet, wherein the system comprises a digital packet testing device, and the method is as follows: the digital packet testing device is used for sending an analog signal to the digital packet to be tested and comparing the signal received from the digital packet to be tested with the analog signal for testing the signal transmission function of the digital packet to be tested; and the digital packet to be tested is used for taking the signal sent by the digital packet testing device as a downlink signal for receiving, and the received signal is taken as an uplink signal for sending to the digital packet testing device. By adopting the system and the method, the difficult problem of testing the geophysical exploration digital packet can be solved, the reliability and the stability in a seismic data acquisition system are improved and accurate reference data are provided for late-stage fine development of an oilfield, marine reservoir exploration and other applications.

Description

technical field [0001] The invention relates to geophysical prospecting technology, in particular to a system and method for testing and realizing geophysical prospecting digital packages. Background technique [0002] Seismic data acquisition system is the most critical equipment in seismic exploration. Seismic exploration operation has the characteristics of large working range and many data acquisition and transmission devices. Therefore, it is very important to test a large number of data transmission units. [0003] The seismic data transmission unit is called a digital package, and the digital package can connect multiple acquisition channels and other transmission packages of the front and rear stages. Usually, multiple cascaded digital packets are towed by the ship responsible for seismic exploration operations. The digital packets close to the towing ship are called the front-level digital packets, and the digital packets far away from the towing ship are called the...
