文章对广泛用于分析和识别天然气水合物稳定带的BSR特征,即,似海底反射特征进行了阐述,并讨论了引起BSR多解性的因素,及其判识天然气水合物稳定带的优劣性,指出了BSR能够预测天然气水合物稳定带的局限性,并探讨了如何应用BSR技术与地质、测井、气源岩地球化学、地球物理等综合研究判识天然气水合物存在范围及其资源量评价。
A seismic technology BSR is used to determine natural gas hydrate. It is expounded that what causes the bottom simulating reflector, and the advantage and disadvantage of BSR in further detail. We elaborate BSR exploratory ranges of natural gas hydrate, BSR reflection characteristics and physical properties of BSR, and meanwhile point out BSR limitations about identifying natural gas hydrate. In addition, we advocate a methodology, which combines, applied conditions of BSR, geologic analysis, well logs and geochemistry. These methods describe a new sight about exploration of natural gas hydrate.
