| 摘 要： | 地震剖面上的反射同相轴只有在代表原始沉积界面的情况下才具有等时意义，也才能成为地震解释和层序地层学研究的基础。但是，挠曲构造作用、成岩、碎屑流沉积作用、重力滑塌、天然气水合物等均可改变或形成新的、具有足够波阻抗差的地层界面并形成地震反射。因而在层序地层学解释中必须识别并排除此类反射轴，否则就会导致年代地层框架的错误认识，所以掌握此类界面的特征和分布规律非常必要。

| Abstract: | In seismic exploration,only after the seismic events on seismic sections are confirmed to represent the sediment interfaces they can be entrusted with isochrone meaning and they can become the basis for studies of seismic interpretation and sequence stratigraphy.However the flexing structure lithogenesis,debris flow sedimentation,gravitational sliding and formation of gas hydrate and so on can lead to form new interfaces which result in seismic reflection,Therefore in sequence stratigraphy interpretation th... |
