THE OFFSHORE MULTI-WAVES AND MULTI-COMPONENTS SEISMIC ACQUISITIONTECHNIQUE--A CASE STUDY OF YINGGEHAI BASIN
海上多波多分量地震采集技术的应用――以莺歌海盆地为例

Offshore multi-waves and multi-components seismic technique is been made much progress.Succeeding apply was got and its exploration effect was good.The main one of reasons of succeeding was the acquisition technique (OBC) was basicly mature.The high quality seismic data was gotten on offshore.Usually,we use three components velocity detector to measure X-component,Y-component and Z-component of velocity field.We use the hydrophone tu measure stress field.The offshore multi-waves and multi-components seismic acquisition system include mainly receive subsystem,focus subsystem,cable subsystem,acoustics subsystem,navigation subsystem and quality control subsystem.The main acquisition manner is using two sailers and double-lines firring a gun to get seismic data.The data connecting system controls two sailers.
