地震反射波中隐含着大量地下地质信息, 如波形的振幅、频率、速度、相关等, 反映了地下和油气藏等特征。这些特征在油藏描述中是储层横向预测的重要手段、在勘探初期资料不多的情况下, 进行综合研究评价, 使用本方法简单、实用。我们用本方法对已知有油气井和无油气井进行验证, 结果绝大部分参数在油气井附近都有异常反映。

There is much gcologie information in scismic rcflection waves, such as the amplitude,frequeney. vclocity, corrclate, and so on. These characteristics are important tools for thetransvcrsc prediction of oil-bcaiing beds. When enough data is available in thc carly period ofexploration, the charactcristic parameter mcthod is simple and suitable to comprchensive studyand evalution of the data. The method was used in the known wells that bears oil and not, thercsults show that most of the parameters are anomalous in the vicinity of the oil-bearing well.
