地震平衡技术及其在地震反演中的应用
|
摘要
地震平衡技术是一种在地震反演中改善井震关系的新技术。它通过单井对比、空间分形建模以及平衡处理的手段 ,克服地震反演中子波空变的影响 ,使得经过地震平衡技术处理的地震剖面井震关系得到较好改善 ,从而可以用统一的子波对研究区的地震资料进行反演
The seismic balance is a new technique that can be used to improve the relationship between seismic trace and well log data. Through well interpretation, 3D fractal modeling and balancing process, it can eliminate the effect of wavelet space?_varying in seismic inversion, making the seismic_well relationship to be obviously improved after the balancing process. As a result, it is possible to use a unique wavelet to conduct seismic inversion for the whole area.
