Development and applications of a new intelligent 3-component geophone

New intelligent 3-componented geophone was designed. The geophone has the characteristics of high sampling speed, high dynamic range, data acquisition and power supply system were integrated in, intelligent control and portable etc. Its inner three sensors were placed in cartesian coordinates and its encapsulation crust has the function of elastic coupling and the structure of composite leveling which can be used for the precise 3-D orientation. As it can convert analog signals to digital datum in original site and eradicate the transmit of analog signals in the system, it has the extremely ability to resist the outside interference and offer a higher guarantee to achieve high resolution of the multi-wave exploration and to furthest reduce the bottle-neck effect of the seismic prospecting. The geophone can communicate to host computer to make an intelligent control network with serial interface bus and a 3-component seismic data sampling system which is all digital is build up. Field test shows this system can be applied to probing fine structure and to analyse the gas-bearing or water-bearing attribute of strata.
