BSR的波形剖面对判断地层中是否存在天然气水合物及其下伏游离气具有重要的意义。当地层中富含水合物及下伏游离气时,其波形剖面有明显的反映,BSR波形极性与海底反射极性相反,大致代表含水合物层的底界。本文根据国内外的研究成果,综合分析了BSR的反射系数、极性和波形特征。
The waveform profile of BSR is of great significance for judging the existence of gas hydrate and its underlying free gas in the strata. When the formation is rich in hydrate and the next free gas, the waveform profile is clearly reflected. The polarity of the BSR waveform is opposite to the polarity of the seafloor reflection and generally represents the bottom boundary of the hydrate layer. Based on the research results at home and abroad, this paper comprehensively analyzes the reflection coefficient, polarity and waveform characteristics of BSR.
