摘　　要：莺歌海盆地地层水的化学特征及其石油地质意义邓孝，陈墨香（中国科学院地质研究所北京１０００２９）关键词地层水，水化学与同位素特征，石油地质环境，南海莺歌海盆地旦水化学分析及水的类型４件水样取自南海写歌海盆地的东方卜！－１及东方ｌ－ｌ－２两口钻井中，两口...In this paper the hydrochemical and isotopic characteristics of four formation water samples from DF1-1-1 and DF1-1-2 boreholes in the fault-depression center of Yinggehei Basin of South China Sea have been studied. Based on both the major ions and the trace elements analysis and isotope determination we have concluded that the formation water was originated from marine factes sedimantary water by metamorphism. It is situated in aclose environment isolated from the present cycle system in atomosphere. So it is judged that the geological environment is favorable for the generation of petroleum and gas.
