摘要

摘要: 为了深入探讨神狐海域BSR特征及其影响因素,对天然气水合物钻探区高分辨率地震资料进行了精细解释。结果表明,神狐海域天然气水合物与BSR具有较好的对应关系,研究区BSR总体表现出多轴(或不光滑)和连续性较差的特征;BSR振幅强度主要与水合物稳定带之下的游离气有关。结合世界典型水合物发现区BSR特征分析认为,"神狐型"BSR的形成可能主要与不同成因水合物在纵向上的相互叠置有关。

Abstract: The high-resolution seismic reflection profiles from gas hydrate drilling zones of Shenhu area in South China Sea were interpreted precisely so as to analyze the features and the controlling factors of BSR (Bottom Simulating Reflector).It has been concluded that gas hydrate and BSR are closely related.In the study area,BSR is characterized by multi-axes and is discontinuous.The amplitude of BSR is mainly controlled by the free gas underneath the base of gas hydrate stable zone.BSR in Shenhu area might be influenced by the vertical combination of gas hydrates of different origins.
