Research Of Multi-scale Matching Methods For Well And Seismic Data

Because different data represents different scale information, so the multi-scale data can not be used for interpretation directly. This is a disadvantage for us to combine multi-scale data. So it is very important to study the matching methods for well and seismic data, which is also the startingpoint of this paper.Paper discusses well tie to seismic using VSP , matching of different seismic section, as well as the correlated problem and actual requirement. Then study the detailed question for getting logging data reflectivity precisely, analyse different wavelet extracting mothods in different situation, point out that resolving the well to seismic tie, fine synthetic seismogram must be made, also fitness estimation methods must be availabl, and making perfect calibration, VSP data should be paid more attention.In order to resolve the seismic to well tie, fine synthetic seismogram must be made; also fitness estimation methods must be available. And to make calibration perfect VSP data should be paid more attention. When resolve the mis-tie of different seismic data (or synthetic seismogram), we firstly describe the theory and algorithms to compute seismic amplitude, time, frequency and phase differences at each intersection point, then give some mis-tie correction results through synthetic and real seismic data. The results show that the mis-tie correction methods are correct and efficient.At the end, paper introduces the algorithm for seismic data extracting briefly, taking particular points and convex hull algorithm for example, illustrates the interface we compiled using part of our result.Paper adopts the way that through combining theoretical model and actual data to proof an idea, and is not only limited in theoretical research, bu also take it's practicability into account.
