摘　　要：正确识别含油气构造中的油、气、水分界面一直是含油气构造评价的一个关键问题。由于油、气和油、水两个分界面的地震反射响应非常微弱 ,再加之环境噪音和仪器设备的限制 ,在通常的地震剖面上很难识别它们。本文利用小波变换的分频显微功能 ,通过正演模型分析 ,比较好地解决了油、气、水分界的识别问题。It is a key question that exactitude recognition of interface between gas and oil and between oil and water in the oily construction. Because of faintness for seismic reflexion response on the interface between gas and oil and between oil and water, forbye the affections of environment noises and the restrictions of the instrument devices, it can not be recognised on usually seismic sections. In this paper, we utilize the component and display fineness functions of the wavelets, and better solving the recognition of the interface between gas and oil and between oil and water for forward model.
