珠江口盆地北坡第三系测井曲线解释沉积环境初步探讨

A PREUMINARY REVIEW ON INTERPRETATION OF THE TERTIARY SEDIMENTARY ENVIRONMENT BY LOG AT NORTH SLOPE OF THE ESTVARY OF ZHU RIVER

南海地质调查指挥部综合研究大队

利用测井曲线解释沉积环境,在目前仍处于摸索阶段。本文根据珠江口盆地现有的测井曲线,重点分析了自然电位测井和自然伽玛测井曲线的形态特征,与国内外某些盆地的典型沉积相测井曲线进行了类比,结合钻井地质录井资料,对盆地北坡第三系沉积环境解释进行了初步的分析和探讨。

It is a matter of common observation that to interpret the sedimentary environment using log is still at its groping stage at present. Based on the existing log obtained from the estuany of Zhu River, an analysis is made with the stress on morphological properties of self-potential and gamma log: Moreover an analogy is dawn between some of the typical sedimentary facies log at home and abroad. And in the light of geological well log data, a prelimiary estimation and remark on the interpretation of Tertiary sedimentary environment at north slope of the basin are made.
