2D Seismic Facies Analysis Constrained by Multi-source Information
Hui Yi · Journal of Oil and Gas Technology · 2011
In consideration of the characteristics of seismic data and the problem of seismic facies analysis,a method based on fuzzy neural network was proposed which was constrained by multi-source information.By arranging the object function of its cluster algorithm constrained by multi-source information,the characteristics of seismic wave shape,the special changes of seismic data,the type of well sedimentary faceis,variety of seismic attribute and sand thickness in wells are integrated into the seismic wave cluster analysis,by which the geological information supervision was implemented in waveform cluster process.The application in southern Sulige Gasfield shows that the method is of high information possess ability,efficient integration and provides more geological information than the traditional method.
