| 摘 要： | 在对南中国海西沙海域地震资料综合对比分析的基础上，本文描述了西沙海域的地震反射特征，并依据地震地层学原理，利用地震反射波的振幅、连续性、内部结构和外部形态等地震反射参数特征，将该区域地层自上而上划分为Ａ．Ｂ．Ｃ．Ｄ四个地震层序：层序Ａ代表从海底到Ｔ＾１１反射界面的地层；层序Ｂ代表从Ｔ＾１１反射界面到Ｔ２反界面的地层；层序Ｃ代表从Ｔ２反界面到５３反射界面的地层；层序Ｄ代表从Ｔ３反射层界面到Ｔｇ反射界

| Abstract: | On the basis of comprehensive comparison and analysis of seismic data from Xishaarea of the South China Sea,this paper presents the characteristics of seismic reflectionsin the area. An interpretation of seismostratigraphy is carried out according to the ampli-tude,continuity,internal structures and external features of the reflection. Therefore,four seismic sequences are divided:sequence A between floor and T,sequence B betweenand T,sequence C between T_2 and T_3,and sequence D between T_s and Tg. In this pa-per,a geological analysis of the four sequences has been made on the basis of the para-metric characteristics of the seismic facies.Finally,author tries to study the history ofthe sedimentary development and potential petroleum resources in Xisha area of theSouth China Sea. |
