Abstract:

It is stated that the propagation of seismic wave in oil & gas reservoirs is accompanied by intense energy attenuation, and the frequency component is higher, the energywill be absorbed more. Thus energy attenuation gradient can be used to detect hydrocarbon sensitively. Conventional Fourier transformsuffers fromtime-frequency resolution problems, while Pseudo-Margenau-Hill distribution has many favorable properties, such as time-frequency marginal distribution, “weak” finite support, time-frequency location, which is one ofCohen class time-frequency distribution. The time-frequency analysis based on Pseudo-Margenau-Hill distribution is presented for energy attenuation gradient estimation, and the log of energy and frequency of higher band is used to calculate the energy attenuation gradient. The practical application shows the effectiveness of the method in hydrocarbon reservoir prediction.
