两种地震道反演方法的比较

对地震道积分法和沃尔什（Ｗａｌｓｈ）函数相对层速度反演法，从方法、处理结果和地震解释等方面进行了比较和分析，并用这两种方法处理了层状模型数据和实际地震资料．结果表明：沃尔什函数相对展速度反演技术和地震道积分技术是两种值得推广的地震资料处理技术；沃尔什函数相对层速度反演技术不仅具有地震道积分技术的优点．而且还具有追踪井间薄地层、高精度计算储层厚度和孔隙度、与油气预测技术相结合计算区块的油气地质储量等特殊用途．

Comparision of Two Seismic Trace Inversion Methods

The trace integral method and the relative interval velocity inversion using Walsh function are theoretically comparied. Model and field seismic data are processed using these two methods. The results show that both methods are useful in seismic interpretation and that the relative interval velocity inversion has not only the same advantages as the trace integral method, but also some special uses such as tracing thin layers, calculating the thickness and the porosity of reservoir, and estimating oil/gas reserve volume of reservoir combining with oil/gas prediction techniques.
