摘要

Abstract

Gas hydrate research has significant importance for securing world energy resources

and has the potential to produce considerable economic benefits. Previous studies have shown that the South China Sea is an area that harbors gas hydrates. However

there is a lack of systematic investigations and understanding on the distribution of gas hydrate throughout the region. In this paper

we applied mineral resource quantitative assessment techniques to forecast and estimate the potential distribution of gas hydrate resources in the northern South China Sea. However

current hydrate samples from the South China Sea are too few to produce models of occurrences. Thus

according to similarity and contrast principles of mineral outputs

we can use a similar hydrate-mining environment with sufficient gas hydrate data as a testing ground for modeling northern South China Sea gas hydrate conditions. We selected the Gulf of Mexico

which has extensively studied gas hydrates

to develop predictive models of gas hydrate distributions

and to test errors in the model. Then

we compared the existing northern South China Sea hydrate-mining data with the Gulf of Mexico characteristics

and collated the relevant data into the model. Subsequently

we applied the model to the northern South China Sea to obtain the potential gas hydrate distribution of the area

and to identify significant exploration targets. Finally

we evaluated the reliability of the predicted results. The south seabed area of Taiwan Bank is recommended as a priority exploration target. The Zhujiang Mouth

Southeast Hainan

and Southwest Taiwan Basins

including the South Bijia Basin

also are recommended as exploration target areas. In addition

the method in this paper can provide a useful predictive approach for gas hydrate resource assessment

which gives a scientific basis for construction and implementation of long-term planning for gas hydrate exploration and general exploitation of the seabed of China.
