The Study And Research On DSU3Three Component Digital Acquisition Unit

With the gradual development of oil and gas exploration in recent years, multiwaveseismic acquisition technology is be attracted more and more attention, and multiwave seismicacquisition work depends largely on the quality of the performance of the three componentdigital detector. DSU3produced by French Sercel,which is the major domestic threecomponent seismic digital equipment. Because of the high price of the DSU3digital geophoneand influenced by subsequent processing technology, make its applications have no large-scalepromotion,but we found DSU3digital geophone test greatly influenced by the environmentand the test result is instability. It brings new problems to the production line workers.Through analysis and research to improve and perfect the manufacturers productiontechnique.It has important practical significance to reduce the technology gap with theinternational and advanced to the world of digital geophone trackingBased on the analysis and research of the conventional detector and the working principleof the new digital geophone,This paper systematically introduces the development, presentsituation of digital three-component geophone and the relative advantages and disadvantagesof the traditional geophone; analysis the working principle and test of digital three-componentgeophone; through specific experiments to find out the specific reason for the test results.This article on the basis of the study of the DSU3crosstalk testing put forward a newcircuit design schematic diagram.
