摘要
以南海北部为研究区,利用MODIS SST(sea surfeca temperatare)数据探讨了海水表面增温异常与海域油气藏和天然气藏区分布的关系。研究发现,已勘探的油气区域在临震前有64%的增温概率,可以将临震前海面温度的增温异常作为一种指示深部油气藏赋存的重要标志;结合地质构造与断裂活动特征,认为南海珠江口盆地深水区、台西南盆地、西沙海槽以及笔架南盆地等是油气或天然气水合物可能的赋存地带。
This paper aims at interpreting the formation of the temperature anomaly of the South China Sea before earthquake.The relationship between the high temperature and the occurrence of oil and gas reserves and gas hydrates is also discussed according to the mechanism of high temperature shown in images.It is found that the temperature increasing probability comes to 64% before earthquake in areas where the oil and gas reserves have been found.It is an indirect method for the exploration of oil and gas resources based on temperature increasing caused by methane emitted from leakage of oil and gas before earthquake.The areas of high temperature shown in the images are mainly distributed in the abyssal zone of Zhujiang River mouth basin,Taixinan（southwest Taiwan） basin,Xisha Islands trough,Bijianan（south Eijia Mountain） basin of the South China Sea,showing probable potentials of oil and gas reserves and gas hydrates.
