Abstract:China's 3一D seismic exploration began in 1966.At that time,the 3一D seismic data were recorded, by D571 photographic seismograph,in a triangle grid seismic layout,which was shot with split一dip spread 600 meter in length.3-D migration of seismic data was performed manually,and the experience of 3一D fault interpretation was obtained.In 1970/s,the analog magnetic tape recording and the swath layout were used,and multiple coverage introduced.The seismic data were processed by computer.In 1980's,th0 seismic data were collected by multichannel digital recording system, and processed by supercompeter.Now,the new techniques are used in field data acquisition and processing,which results in good exploration result and economic effect.3一D seismic exploration must be prudently used because it is much more expensive than 2一D seismic exploration.
