合肥盆地地球化学空间场属低背景、低湿度和非均匀场范畴。烃类指标浓度在盆地周边高、中间低。化探异常总体上表现为东强西弱、南北分带,异常上方三维荧光图谱以B型为主、P型次之,与轻质油、煤成烃特征相对应。从地球化学角度建议合肥盆地下一步勘探工作应继续采用综合勘探手段,重点解剖吴山庙—双墩集、桃溪—三河、曹庵—朱巷—白龙镇等不同类型的化探异常。 The Hefei Basin geochemistry space field is of low background, low humidity and non-uniform field categories. Indicators of hydrocarbon concentration in the basin around the high, low in the middle. The geochemical anomalies generally show the weakening of the east and the west, the north-south zoning, and the top three-dimensional fluorescence spectra above the anomalies are dominated by type B, followed by p-type, corresponding to the light hydrocarbon and coal-forming characteristics. From the geochemical point of view, it is suggested that further exploration work should be continued in Hefei Basin, focusing on the dissection of different types of geochemical anomalies such as Wushanmiao- Shuangdunji, Taoxi-Sanhe, Caoan-Zhuxiang-Bailong.
