摘要:

通过对青海木里冻土区三露天井田三维地震资料进行处理,在岩石物理分析和地震响应特征分析模拟的基础上,获得了研究区深部构造和地震特殊处理如AVO 特征分析等结果。结果显示,该区天然气水合物的分布与构造关系极为密切,研究区的天然气水合物分布主要受构造控制。在构造发育区,断裂和裂隙发育,其内的天然气水合物分布特征明 显,这一结果与实际钻探结果亦相吻合。

Abstract:

Through processing 3D seismic data acquired in Sanlutian mining field in Muli permafrost area, Qinghai, based on the petrophysical analysis and the seismic responsefeature analysis, the deep structure and special seismic processing results such as AVO characteristics of the study area were obtained. The results reveal that there exists extremely close relationship between the distribution of gas hydrates and the structure; the distribution of gas hydrates is mainly controlled by the structure. In the area where faults and fractures are developed, the distribution feature of gas hydrates are obvious; it is coincident with the drilling result.

Key words: Muli area, permafrost area, gas hydrate, deep structure, 3D seismic profile
