On Pwave Seismic Detection Methods for Fractured Reservoirs
Huiqun Xu · Journal of Oil and Gas Technology · 2007
Fractured reservoir prediction was the critical point of hydrocarbon exploration,multiple methods were usually used for research.In consideration of the situation of fractured reservoirs,study on multiple mathads was carried out for predicting fractured reservoirs based on p-wave seismic data.The detecting methods were introduced for NMO velocity azimuth changes,orthogonality seismic survey line with p-wave time-difference,the azimuth changes for p-wave AVO detecting fractures,edge detecting technique for prediction of fracture development band,technique for predicting fracture development band and fracture detecting method of seismic attribute with coherent data.From numerical calculation or application the applications of p-wave seismic data detecting fracture reservoirs is discussed.
