| 摘 要： | 在深水钻井中,浅水流是一种常见的地质灾害。中国正在进行深水油气勘探,十分有必要开展这方面的地质灾害研究。介绍了浅水流的形成机制及地球物理特性。目前用于识别和预测浅水流的手段有测井和反射地震两大类方法。主要介绍了几种用于参数提取的地震反演方法,如传统Dix反演、叠后振幅反演、层析反演、叠前振幅反演等。 |
| 关 键 词： | 浅水流 异常高压 Vp/Vs 测井方法 地震反演 深水油气 |

| Abstract: | Shallow water flow (SWF) is a type of common geohazards in deepwater drilling. China is exploring the deepwater hydrocarbon, and it is essential to study the SWF geohazards. The formation mechanism and geophysical characteristics of SWF sands are firstly introduced. At present, the techniques for detecting and predicting include logging and reflection seismic exploration. Several seismic inversion methods for parameters picking are mainly introduced, such as, conventional Dix inversion, poststack amplitude inversion, tomographic inversion, and prestack amplitude inversion. |
| Keywords: | SWF overpressure Vp/Vs logging seismic inversion deepwater hydrocarbon |
