| 摘 要： | 在低信噪比地区，由于受地震波有效频带的限制，传统的反褶积方法、谱白化方法均不能得到令人满意的结果，而ＢＣＩ技术又存在严重的多解性，因此文中提出以“接近地震子波”的小波函数作为基本小波，利用小波变换技术提高过井地震剖面分辨率的新方法．经实测资料验证表明，该方法是有效的．

| Abstract: | The conventional deconvolution or spectrum whitening method can not yield high resolution seismogram due to restriction of "effective band width" in the low S/N ratio area. Ambiguity due to the band constrained inversion (BCI) method is serious. A new method is proposed to enhance the resolution of the seismogram across a well by letting the wavelets to approach those of the seismic wavelets. Efficiency of the method is demonstrated using field data from oil field. |
