Abstract:Belonged to fluvial facies deposition,thin reservoirs of Minghuazhen formation in the 4th structure zone of Nanpu,are vertically superimposed with rapid lateral variance.From geologic and geophysical characteristics of Minghuazhen formation in the 4th structure zone,we investigate regional sedimentary features by seismic attributes,qualitatively predict sand bodies of meandering river by spectrum decomposition,predict the favorable reservoirs distribution by lithologic indicator simulation,and carried on oil and gas detection combining with drilling and logging data.According to our results of reservoir prediction,two wells deployed got good oil gas show.
