A new approach to block evaluation in Xihu Depression,the East China Sea;

The Tertiary drilling, logging and seismic interval velocity data from the Xihu Depression of the Donghai Sea were used to calculate the residual pore fluid pressure of hydrocarbon source layers.

The Pinghu Formation, which is the major hydrocarbon-generating horizon in the Xihu Depression of the East China Sea, was in the threshold of hydrocarbon generation during the sedimentation period of the Huagang Formation and has good conditions for hydrocarbon generation and expulsion.

Based on the detailed analyses and discussion of petroleum geological conditions of the Xihu Depression, the East China Sea, this paper systematically calculated the potential petroleum resources, resources in leads and total resources, and then established the series and structure of resources and presented the distribution characteristics of discovered and undiscovered resources.
