摘要
Prospecting area is located in a high-steep complex area in east Sichuan.Surface and seismic geological condition are complex in work area.Because the geological structure was subjected to the stress action of multi-stage multi-formation systems,it is difficult to beat out the interrelationship among structures and breakpoint location and combination relation of fault although 2D seismic prospecting has been performed in this area for many times.The seismic resolution is improved and the various structural characteristics and their interrelationship are made sure through selecting the field acquisition operation mode,optimizing the seismic data processing technology and using the 3D visualization technology to conduct the comparison and interpretation of seismic data.The fault is finely described from a 3D angle to obtain an accurate and reliable result.In particular,a large concealment high zone is found to provide the rich and reliable information for further potential tapping,which proves that the method is the most accurate prospecting method to make sure the interrelationship among various structures in complex structure areas with multi-formation system.
