【摘要】 随着油气勘探开发的不断深入,地震勘探的目标越来越复杂,勘探深度不断增加,勘探难度越来越大,对勘探精度的要求也不断提高。为了满足精确勘探开发的要求,各种提高地震资料分辨率的方法技术应运而生。为此,对小波变换分频重构、广义S变换、反Q滤波这3种提高地震数据分辨率的方法进行了探讨,并将其应用于叠后地震资料的提高分辨率处理,结果表明,它们都能在一定程度上提高地震资料的分辨率,但各有其缺点,在实际使用时,要根据原始地震资料的特征及具体的处理解释需要,选取合适的提高分辨率方法和适当的处理参数。更多还原

【Abstract】 With the development of oil and gas exploration,the seismic exploration targets are getting deeper,more complex and difficult.Therefore,requirement in accuracy is becoming more rigorous.A variety of techniques for improving seismic data resolution has emerged.This paper evaluates the frequency-division reconstruction with wavelet transform,the generalized S-transform,and the inverse Q-filter method in terms of resolution improvement.Though all methods are capable of improving seismic data resolution to some extent,each has its own defects.In practice,the method for resolution enhancement and its parameters should be selected according to the quality of the data and the objectives of the data processing.更多还原
