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.

Abstract

The invention discloses a seabed seismograph prototype and actual measuring method; a prototype test process should mainly test sea detection functional performance indexes, and also tests the equipment reliability and deep sea pressure resistance equipment performance indexes as supplements. The testing principle combines lab tests and field tests; the testing contents comprise the following parts: signal acquisition recording function test, equipment work mode switching and work state monitoring function test, equipment low power consumption and work time test, equipment deep sea pressure resistance performance test, equipment underwater remote control and locating function test, and performance test of the seabed seismograph applied to 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. Th...
