Abstract：D seismic exploration has basically been carried out in whole area of Zhongyuan Oilfield,among which the 3-D seismic data in Baimiao area was acquired in 1987.Because of the characteristic of complex sub-surface conditions,developed underground minor faults,rapid-changed lithology and deep-buried targets in this area,the oil/gas accumulation rule was not clearly defined although the data was repeatedly processed many times.Therefore,a 3-D seismic exploration was again carried out in a period from winter of 2001 to spring of 2002.Using 3-D geometry with changeable bin for field acquisition,adopting hi-fi processing modules in data processing and using such advanced interpretation techniques as high-precise synthetic layer-labeling,seismic forward analysis,coherent data volume analysis and visualization in interpretation of seismic data,so that the resolution and S/N ratio of seismic data have been greatly improved,providing condition for lithologic inversion,attributes analysis and reservoir prediction.The second 3-D seismic exploration in Baimiao area had characteristic of instantly becoming effective and short investment period,which can provide a shortcut for increasing resource potential and production capacity in maturing oilfield.
