Fault Sealing is very important for both hydrocarbon accumulation and injection production well arrangement. The diagnostic method of fault sealing for the complex block flauted oil field in Dagang is presented in this paper. Two methods are used in this example. First, In order to calculate the pressure on either side of the fault, its interval velocity is extracted based on the model inversion from seismic data, and the fault sealing is determined according to the pressure continuance in that formation. Second, numerical simulation is applied to analyze the fault sealing. On the controlled conditions (Fault Sealing), WWCT is simulated, and then to fit with WWCTH in the producction well. The degree of fitting is used to determine fault sealing.
