Collection and test system for offshore earthquake data

Abstract

The invention discloses a collection and test system for offshore earthquake data, and relates to the technical field of geophysical exploration. The collection and test system for the offshore earthquake data achieves operation and corresponding processing on the offshore earthquake data. The collection and test system for the offshore earthquake data comprises a control unit, a power module, a test function module and a collection function module, wherein the test function module and the collection function module are connected with the control unit, the control unit is used for issuing a test instruction, and receiving and processing test data sent by the test function module, the test function module is used for configuring parameters of the collection function module according to the test instruction, and receiving test data sent by the collection function module, the collection function module is used for collecting data according to the configuration, carrying out preprocessing on the collected data to obtain the test data, and sending the test data to the test function module, and the power module is used for providing electric energy for the modules. Due to the fact that optical fiber transmission, a CPCI case and the like are not adopted in the collection and test system for the offshore earthquake data, the collection and test system for the offshore earthquake data is more compact in integral structure and convenient to carry, and a good test platform is provided for real-time test operation of the offshore earthquake data.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a marine seismic data acquisition and testing system. Background technique [0002] At present, offshore high-precision seismic acquisition technology, as the core technology for the exploration and development of deep-water oil and gas field resources, directly restricts the technical level of my country's deep-sea oil and gas exploration and development technology and equipment development; Better solve the problem of my country's offshore deepwater oil and gas resource exploration, greatly increase the success rate of deepwater oil and gas resource exploration, increase the recovery rate of offshore oilfield development, and promote the development of my country's high-end offshore engineering equipment and deepwater oil and gas exploration and development technology service industries. Among them, the technical level of the acquisition circuit test system as a ...

Problems solved by technology

[0003] In the seismic data acquisition circuit test system in the prior art, the acquisition board collects data and uploads data packets, and then transmits to the control system through a CPCI (Compact Peripheral Component Interconnect, Compact PCI) chassis via optical fiber, and the control system then performs corresponding tests. And processing; Among them, the data upload process needs to be equipped with a 380V power supply voltage to be transmitted to the control system through optical fibers. The data transmission process is more complicated and can only be realized through optical fiber transmission; the CPCI chassis is relatively large, and the control system and CPCI chassis are not easy to carry; It is necessary to configure a special tow to place the above-mentioned chassis and control system in order to realize real-time testing of marine seismic data

For now, the existing acquisition circuit test system cannot provide services for the acquisition of marine seismic data due to the above-mentioned shortcomings of large volume and complex transmission mode.
