摘　　要：珠江口盆地碳酸盐岩展现了良好的油气勘探前景,B6-1井碳酸盐岩厚度为白云凹陷之最,灰岩段纵向分布在珠海组和珠江组,被玄武岩分隔为三段。对其灰岩段系统的碳氧同位素及各类元素测试分析研究,对恢复灰岩段沉积期古环境、古气候、古盐度、海平面变化及三级层序界面等,为该区碳酸盐岩油气勘探提供新的依据具有重要意义。The carbonate rocks in the Pearl River Mouth Basin show good oil and gas exploration prospects. The carbonate rocks in well b6-1 are the thickest in Baiyun sag. The limestone sections are longitudinally distributed in Zhuhai Formation and Zhujiang Formation,which are divided into three sections by basalt. The test and analysis of carbon and oxygen isotopes and various elements of the limestone section system is of great significance to restore the paleoenvironment,paleoclimate,paleosalinity,sea level change and third-order sequence boundary of the limestone section in the sedimentary period,and provide a new basis for carbonate oil and gas exploration in this area.
