Research On Testing Method Of The Shallow Four-Component Geophone

Judging from our country coastal waters geology and seismic prospecting current situation, the earthquake prospects four component exactly being to face Duoboduo component the seismic prospecting forging ahead, four component prospects a technology being able to resolve many difficult problems prospecting, effect forecasting aspect in structural identification, rock sex and shallow tier of gases Tibet resolving the small fault and low extent is very good, also can arrive at fairly good effect up in the field of aeolotropism research.A lot of Petroleum Company, exploitation and application contracting business and "R&D" institution beginning to hanker to prospect this technology in four component, but running after prospecting the degree of difficulty increasing by having aroused people to new technique, detector testing method research is very necessary therefore, to four component. Main part being completed works as follows:First, be completed from being composed of the characteristic and effect aspect theoretically, to four-component the geophone analysis. That the geophone is that a hydrophone (piezoelectric geophone), perpendicular one geophone and mutually orthogonal horizontal two geophones (moving-coil geophone) assembling is become as well as having direction fixer system one geophone guarantee serviceability for, it does four-component receive the earthquake signal.Secondly, have accomplished the detecting to four-component. Using a vertical, two horizontal electric incentives stimulate circulation mode, the various parameters (frequency, sensitivity, damping, resistance, etc.) were individually tested.Thirdly, have accomplished the hardware wiring design to STC12C5A60S2monolithic machine and their circuital peripheral design, especially, have carried out necessary analysis on each modules structure, connection, operating principle and relevance parameter, have solved the problems encountered in the design.Fourth, has been completed hard hydrophone software designs that to fourth components. And have realized the data collected, data sending, signal happening preparing liquid crystal display function, the anti-interference having carried out a software on system designs that, messenger system stabilizes especially reliably.Fifth, the software has accomplished to four component has been designed, has related functions implemented.
