Prototype and actual measurement method of a seabed seismograph

Abstract

The invention discloses a prototype structure of a seabed seismograph and a method for actually measuring the prototype. The prototype test should mainly focus on the performance indicators of ocean detection functions, supplemented by equipment performance indicators such as equipment reliability and deep-sea pressure resistance, and the testing principle adopts laboratory testing and field testing. Test combined scenarios. The test content mainly includes signal acquisition and recording function test, equipment working mode switching and working status monitoring function test, equipment low power consumption and working time test, equipment deep sea pressure performance test, equipment underwater acoustic remote control and positioning function test, and submarine seismograph Performance testing for underwater target detection.

Description

technical field [0001] The invention relates to a prototype of a seabed seismograph and an actual measurement method. Background technique [0002] Two-thirds of the earth's area is ocean, and today's seabed observation technology has become a new hot spot. With the development and improvement of OBS (undersea seismograph) exploration technology, OBS has a very obvious effect in the fields of deep ocean structure research, oil and gas detection, and underwater target detection. At present, the United States, the United Kingdom, Japan and other countries have invested a lot of manpower and material resources in the development of submarine seismographs. my country has also achieved breakthroughs in related key technologies and carried out many sea trials. [0003] The success or failure of the seabed acquisition work of OBS in the seabed survey and research depends on whether the performance and functional indicators of the acquisition equipment OBS meet the requirements.

Problems solved by technology

Since the research and development of submarine seismographs in my country started relatively late, there is no systematic prototype measurement plan. Therefore, it is necessary to design a set of prototype measurement methods for testing the performance indicators and functional indicators of submarine seismograph prototypes.
