针对声波测井曲线不能很好地区分岩性、造成传统反演存在储层预测精度较低的问题,通过储层特征曲线重构的方法,利用能够突出反映储层特征的曲线高频部分和声波曲线的低频部分,重构能够准确的反映地层物性变化的拟声波曲线,代替声波曲线进行地震波阻抗反演.结果表明该方法突出了储层响应特征,提高了反演结果的可解释性.文章利用声波曲线重构技术对元坝工区雷口坡组岩溶储层进行了反演,结果与沉积相的认识及宏观预测的储层展布范围一致,有效的指导了生产.

This paper makes an approach to the application ofpseudo acoustic inversion to the prediction of karst reservoir by the example of the Leikoupo Formation in the Yuanba region. The study indicates that seismic wave impedance inversion by use of reservoir characteristics curve reconstruction, low frequency part of the sound wave curve characteristic of reservoir and pseudo acoustic inversion instead of sound wave curve is of good results.
