利用地震反射法评价海底天然气水合物资源
|
摘要
海底天然气水合物是２１世纪的重要新能源，本文介绍了利用地震反射法来识别海底天然气水合物 的存在和分布特征，并对其资源量进行评价的方法。根据地震剖面上的拟海底反射层（ＢＳＲ）识别水合物 的存在，并结合地震弹性参数和利用沉积物的孔隙率等特征，来评估海底天然气水合物的资源前景。
This paper introduces in brief the seismic reflection method for the diagnosis and resource evaluation of the marine gas hydrate deposits. The BSR (Bottom Simulating Reflection) of the seismic cross-section may identify the existence of marine gas hydrate and its distributing characters. We can evaluate the amounts of the gas hydrate according to the BSR characters in the light of the seismic elasticity parameters and sediment porosity characters.
