小波波阻抗反演技术的改进及应用

针对松阵盆地中部组合油层在空间上分布薄且横向变化快的特点，以提高复杂地质条件下的储层横向预测精度、提高探井成功率为目的，对小波波阻抗反演技术在应用中存在的问题进行了改进，一是针对大倾角地震资料信噪比低的问题了倾角扫描技术；二是针对波阻抗剖中常出现锯齿状波形而引入中值滤波技术，结果表明，改进后的小波波阻抗反演技术，能够改善大倾角地层地震资料的反演效果，可以进一步提高油藏描述精度，效果较好。

Improvement of Wave Impedance Inversion Technique of Small Wave and Its Application in Reservoir Description

According to the characteristic of special thin distribution and much horizontal change of the consistent reservoirs in the central part of Songliao Basin, this paper reforms the application problems of wave impedance inversion technique of small wave in order to increase the horizontal prediction accuracy in complicated geologic condition and increase the success percent of exploration wells.
