Аннотация

The search for small hydrocarbon deposits is the a difficult task for seismic exploration. For such reservoirs often there is no connection with the structural factor and they are weak manifested in the dynamic characteristics of the wave field. As a result, many small hydrocarbon deposits can be missed. The developed technology based on the Prony decomposition is a tool for studying the dynamics features of reflected waves at different frequencies. Take into acount that high-frequency oscillations react most acutely to the presence of collectors and the type of fluid, it is possible to identify them. The report provides several examples of relevant analysis. In particular, the reaction of seismic sygnals on the water deposit is demonstrated. It manifests itself at a frequency of 39 Hz, and with increasing frequency, such a reaction decreases to complete disappearance. At the same time, in the presence of oil or gas, there is an increase in the response of reflected signals at frequencies of 47 or 75 Hz, respectively, and its preservation at higher frequencies. The nature of the response of the reflected wave amplitudes is illustrated on figures and tested drilling.
