业已证明 ,地震振幅及其随炮检距变化显著时 ,在好的远景圈闭勘探中具有较好的效果 ,与仅仅使用构造信息相比 ,它能显著地降低勘探风险。当烃类物质取代了地下无处不在的盐水时 ,岩石特性的变化将引起地震振幅的变化。这些岩石特性的变化反过来控制了ＡＶＯ响应和反射的强度。1
It has been shown that seismic amplitudes and their significant variations with offset can provide good results in good prospect-trap exploration and significantly reduce exploration risks compared to the mere use of tectonic information. When hydrocarbons displace underground ubiquitous salt water, changes in rock properties can cause changes in seismic amplitude. These changes in rock properties in turn control the intensity of the AVO response and reflection. 1
