【摘要】 由于不同井地资料代表不同的尺度信息,也就不能够直接将多尺度井地资料进行对比解释评价,这也给多尺度井地资料的联合应用带来了不便。因此,做好井地资料多尺度匹配是精细储层预测的必要一步,它具有举足轻重的作用,这也是论文的出发点。论文主要讨论了测井资料联合VSP与地震资料之间的匹配、地震资料之间的匹配整合以及相关理论问题和实际需要。其中详细研究了反射系数精确求取中的细节问题、子波提取方法以及考虑空变时变的子波处理,强调了合成记录的精细制作,及其与地震剖面匹配检验。同时在匹配中要注重VSP对于合成记录标定的作用;在剖面的匹配整合处理中,对存在时差,振幅差异,相位差异和频率差异的不同地震资料(或是合成记录)进行相应的校正处理,介绍了匹配滤波方法、多分辨率匹配技术和迭代匹配方法。其中迭代匹配方法是一种将交点时差、振幅、频率和相位一次性解决的地震资料匹配方法,有一定的新意,且通过模型试验和实际数据测试都得到较好的闭合效果。论文最后就数据抽取算法(特殊点法和凸包算法)做了简单介绍;同时也对我们就部分工作编制的成果界面做了说明。论文在论证方法上大量的采用理论模型与实际资料相结合的方式,在宗旨上不局限于理论方法研究也考虑了方法的实用性。更多还原

【Abstract】 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.更多还原
