摘要
在天然气水合物的地震资料解释过程中,常规(叠加和偏移)地震剖面上难以识别BSR、水合物成矿带以及游离气带的位置。通过多年的实践,笔者认为AVO(Amplitude Versus Offset)反演、波阻抗反演、地震瞬时属性和能量半衰时剖面。能够较好地揭示水合物的地球物理异常特征,从而给识别水合物和划分水合物的存在区域提供了有力的证据。
During interpretation of the profile of natural gas hydrates, it＇ s very difficult to distinguish BSR, gas hydrates zone and free-gas zone from the profile of stack and migration. Through our practice in these several years, we think that the profile of inversions of AVO, inversions of wave impedance, instantaneous profile and half-time energy profile, in which abnormal physical geography character can be shown preferably. So that we can use these kinds of profile to judge seismic character of gas hydrates, and the area of them that exist.
