珠江口盆地文昌A凹陷恩平组沉积环境分析
Analysis of Sedimentary Environment of Enping Formation in Wenchang A depression of Pearl River Mouth Basin
摘要
珠江口盆地恩平组为一套含煤碎屑岩地层。通过对岩性，测井曲线，微量元素和地震反射特征的综合分析，结合区域构造背景，分析了该盆地文昌A凹陷及其周边恩平组的沉积环境。研究发现：恩平组是湖泊萎缩形成的，岩石普遍为暗色，南部临近物源，可见分选差、磨圆差的粗碎屑岩。沉积相类型主要包括滨浅湖相，中深湖相，扇三角洲前缘相等。滨湖相是碳质岩的有利分布区。
Abstract
Enping Formation of Pearl River Mouth Basin is a set of coal-bearing clastic rock formation. Through observation and comprehensive analysis of lithology，well logging，microelements and seismic reflection characteristics，in combination with regional tectonic background，analyzed sedimentary environment of Enping Formation in Wenchang A depression.The research shows that Enping Formation formed from atropous lacustrine，the rock color is generally dark，the south is close to the matter-source，coarse clastic rocks of poor sorting and bad rounding can be found. Sedimentary facies types mainly include shore-shallow lacustrine facies，semideep-deep lacustrine facies，fan delta front facies. The shore lacustrine facies is the favorable distribution area of carbonolite.关键词
