摘要
下寒武统荷塘组是下扬子地区重要的页岩气勘探层位之一,通过野外地质考察,并结合区域构造演化背景分析,以下扬子地区下寒武统荷塘组富有机质泥页岩为主要研究对象,结合实钻井宣页1井、皖宁2井等分析了下寒武统页岩特征,探讨了其有利勘探方向,认为黄桥—无锡低褶带是下扬子地区下寒武统页岩气勘探的较有利方向。
The lower Cambrian Hetang Formation is one of vital shale gas exploration horizons in the lower Yangtze area. Taking the organic matter rich argillutite as the subject investigated, through field geological survey and regional structural evolution setting analysis, combined with practically drilled Xuanye No.1 and Wanning No.2 wells analyzed lower Cambrian shale features, discussed favorable exploration orientation. The result has considered that the Huangqiao—Wuxi low folded belt is the favorable lower Cambrian shale gas exploration orientation in lower Yangtze area.
