Abstract：On the basis of derivative Fillippone algorithm,using seismic data,the paper evaluates the formation pressure coefficients and discovers the pressureanomalous zone. The key lies in acquiring highresolution wave impedance volume by loggingconstrained inversion and further computing true formation velocity V_i;then,the normal compaction trend interval velocity V_N and max velocity V_ max can be acquired by using polynomial trend analysis for interval transient time of acoustic log. Because the hypothetic condition of the approach is difficult to be strictly met,the acquired predicted analytic pressure parameters only act as complement of other analytic means. The results from application of the method in KHD oilfield are relatively coincident with real drilling results,which showed that the method is a useful studying tool.
