| 摘 要： | 运用层序地层学的方法对珠江口盆地白云凹陷13.8 Ma以来的深水扇进行分析,建立了浅海、陆架区的沉积物(高位时期)与深水沉积(低位时期)之间的联系,进而研究了白云凹陷13.8 Ma以来的深水扇体的岩性和沉积物组成,此方法对于预测不同深水沉积单元的岩性和预测深水沉积系统的沉积物粒度及潜在储层的质量有重要意义。深水油气勘探的关键是精确地预测深水沉积储层,白云凹陷深水勘探有别于浅水陆架勘探,应先预测深水目标的岩性特征和储层条件,再进行地球物理、圈闭评价等工作的勘探流程。

| Abstract: | The deep-water fan since 13.8 Ma in the Baiyun sag of the Pearl River Mouth Basin is analyzed using sequence stratigraphy method.The relationship between shallow water and continental shelf sediments(highstand) and deep water sediments(lowstand) is established to study the lithology and sediment composition of the deep-water fan since 13.8 Ma in the Baiyun sag.This method is of great significance to prediction of the lithology and sediment grain size in deep water unit as well as the quality of potential re... |
