摘要
天然气水合物作为一种新的烃类资源在人类未来能源中具有极大的潜力,由于天然气水合物大多储藏在水深300 m以下的海底沉积物及冻土地带中,因此研究的重要内容之一就是利用地震准确地识别和预测其分布与资源量。地震识别的特征有似海底反射(BSR)标志特征、BSR强反射界面之上的高速异常带、BSR附近存在的弱振幅或振幅空白带、AVO的正负异常和BSR的极性反转。文章在综合分析的基础上,指出了天然气水合物研究中存在的主要问题,并论述了该项研究在地震资料的特殊处理技术研究、海底地球化学探测技术、水合物高保真度取心技术、人工源海底电磁探查技术和遥感图像信息处理技术等方面的发展趋势。
As a kind of new hydrocarbon resources, the natural gas hydrate is of very -great potential in the coming energy resources of mankind. Because the natural gas hydrate is mainly stored in the sea bottoms with water depth of over 300 m and in the permafrosts, one of the key researches is to identify and predict accurately its distribution and resources. The seismic identificafion characteristics include the bottom simulating reflection (BSR) mark, the high-ve-, locity anomaly zone above the strong BSR boundary plane, the weak or blank amplitude zone near BSR, the positivel/ negative anomaly zone of AVO, and the polar reversion of BSR. The main problems existing in natural gas hydrate research are pointed out and the expanding trends of the research on the following aspects, such as the specially processing techniques of seismic data, the detection techniques of submarine geochemistry, the high-fidelity coring techniques of hydrate, the submarine electromagnetic detection techniques of man-made explosion and the information processing techniques of remote sensing image, are stated in the paper on the basis of comprehensive analysis.
