| In order to improve the production of oil, natural gas, the development of mineral exploration technology is heading for 3D high-precision multi-component seismic exploration, looking for the minerals product stored in shallow, thin layer. Geophone as the reflection wave receiver in seismic exploration, it must satisfy 3C3D seismic exploration's various property requirements such as frequency band, crosstalk, sensitivity and adaptability in field operation.This paper is based on"MOEMS three-component acceleration seismic geophone"which funding by the national natural science funds projects. It introduced the working principle of single component detection unit, structure design and key components'characteristics. We found the dynamic behavior of detected signals has nonlinear, time-variation, multi-variable and strong-coupled. And research for the 3D oscillators'coupled problem in three three-component acceleration seismic geophone. Aimed at this problem, on the basis of realized research we proposed a method used a multivariable fuzzy-neural net work decoupling controller, designed and simulated the corresponding decoupling scheme. The results show that this method is stable and reliable, giving some help to the development of three-component acceleration seismic geophone. |
