根据冲绳海槽多道地震资料的处理解释,在16条地震剖面上发现了水合物拟海底反射层BSR,经过AVO、波形反演等特殊的处理技术,首次直接利用BSR圈定了冲绳海槽天然气水合物具体分布范围,直接利用数据得出了天然气水合物稳定带厚度在冲绳海槽的分布趋势,认为海槽南部最厚,中部次之,北部最薄,并通过计算得出了冲绳海槽水合物稳定带的厚度和水合物资源量,对今后海槽水合物勘查和资源量评价具有一定的指导意义。 According to the processing interpretation of multi-channel seismic data in the Okinawa Trough, the BSR of the quasi-seabed reflective layer of hydrate was found on 16 seismic sections. After the special treatment technologies such as AVO and waveform inversion, the BSR was used to define the natural gas in the Okinawa Trough Hydrate specific distribution range, the direct use of data obtained gas hydrate stability zone thickness distribution trend in the Okinawa Trough, that the southernmost trough the middle, followed by the middle of the northern thinnest, and calculated by the Okinawa Trough The thickness of hydrate stability zone and the amount of hydrate resources are of guiding significance for future taphole hydrate exploration and resource assessment.
