| 摘 要： | 子波提取是采用优化快速模拟退火法进行反演，提高叠加地震波分辨率的关键。本文应用最小平方法计算在合成地震记录与井旁地震记录差平方条件下的地震子波，制作合成地震记录，并进行反演以达到提高信噪比的目的。这是一种通过钻井资料来去噪、提高地震分辨率的方法，该方法原理简单、使用方便、效果较理想，有推广的意义。

| Abstract: | Wavelet extraction is the key to the inversion by means of speed analog annealing in order to enhance the resolution power of superimposed seismic waves. This paper calculates seismic wavelet under conditions of the square of the difference between composite seismic records and well seismic records by method of least square and makes composite seismic records and inversion in order to enhance signal - to - noise ratio. This is an ideal method to enhance the resolution power of superimposed seismic waves. |
