The summarize of multifocusing imaging technology

LUO Yin-he(The Department of Geophysics, China University of Geosciences, Wuhan 430074, China)  
MF(Multi-focus)technology belongs to a group of methods that can be characterized as macro-model and independent imaging methods. In this method large superpose of seismic traces arte stacked, each of which can span many common midpoint(CMP) gathers. This method applies optimized focusing parameters updating instead of traditional velocity updating and MF technology efficiently avoids the "velocity problem" when getting the precise imaging. MF method can be applied widely in the field of seismic data processing and inversion (i.e. near surface problem, multiple removal, etc.), specially it can do well in complex geology problems. Therefore , the MF technology will have many developable chances in seismic exploration.
