Abstract
Reliable fluid identification results are very important for us to improve the success rate of oil exploration. At the present stage, recognition of reservoir fluid mainly rely on seismic amplitude anomalies and elastic parameters difference, in practical applications, there are often problems that seismic amplitude response is not obvious to hydrocarbon and the elastic parameters distinction between hydrocarbon and water is not strong. So, using conventional methods would lead to multiplicity of hydrocarbon detection. The oil-bearing reservoir leads to more strong velocity dispersion and energy attenuation of seismic wave than water-bearing reservoir, it is feasible to use velocity dispersion and energy attenuation to detect hydrocarbon reservoir. In this paper, we obtain hydrocarbon-sensitive factor by merging velocity dispersion property and energy attenuation property and using the information of hydrocarbon information of wells to control the merge answers, and proposed the velocity dispersion and energy attenuation attributes fusion hydrocarbon detection method. The practical data test of Bohai A oilfield proved that this method can effectively predict hydrocarbon reservoirs.
