Abstract:
Shawan formation of Chunguang oilfield in Neogene system is the"bright spot"of main reservoir type for increased production and enhanced efficiency.Firstly through speed statistical analysis,the sand mudstone speed characteristics of Shawan formation have been made clear.Based on quality analysis of seismic data and detailed calibration of synthetic seismogram,by using seismic attribute technology and in combination with fine seismic forward modeling technology,the cascading phenomenon of reservoir development zone has been identified.With further application of oil-bearing detection technology,the favorable oil-bearing areas can be identified.Through comprehensive analysis,the well location has been deployed and good development effect has been achieved.
