Abstract:The statistics of field data acquisition,data processing,data interpretation,equipment manufacture,education and training demonstrate that China has a versatile geophysical exploration contingent which covers all necessary technical fields and has advanced equipments.In view of the complicated seismic and geological conditions in east and west parts of China,we must solve the following tough problems in geophysical exploration;very low primary signal-noise ratio,terrible static moveout,poor image,low seismic resolution and difficult identification of lithology in continental-fades sandstone and shale series,To solve these problems,we have recently taken the following measures: •using high seismic multiplicity, •developing the necessary field static correction techniques which are suitable to different terrain and various surface layer conditions,•developing new application softwares, •wide use of improved 3-D seismic techniques, •comprehensive use of geological material,logging data and other non-seismic informations, •applying interactive interpretation work station, •bringing the non-seismic exploration methods into play.These effective measures greatly enhance the ability for china's geophysical exploration to ascertain complex geologic structure. Finally,the paper looks into the future of China' s oil geophysical exploration in the 8th national five-year plan period.
