Abstract:

The second and third submembers in the third member of Shahejie Formation(Es32+3) in Gaoshangpu Oilfields are lakeshore sedimentary system of fan delta facies.The fan delta facies consists of three subfacies,and delta front subfacies is the main body.Nearshore subaqueous channel sandbodies developed well and these are most potential oil bearing places,distal sheet sands are secondary.It has been proved that sedimental facies and belts bear fine correlation with oil bearing potential.According to this point,fault blooks within the study area were estimated and predicted,the results suggest that thirty of them are favourable hydrocarbon bearing belts and twenty eight of them are secondary favourable belts.
