合肥盆地综合物探解释效果分析及油气勘探潜力

合肥盆地是经历40多年勘探的老区,但就勘探程度而论,至今仍处于普查勘探阶段,各家的认识、分歧较大。本文应用重、磁、电、震等综合物探资料,综合分析研究,发现了下侏罗统“影子盆地”,进行原型盆地恢复,凸现了原沉积盆地范围,并将盆地划分为4个勘探区带;指出下步勘探方向为盆地南部。

Comprehensive geophysical interpretation and oil and gas exploration potential in Hefei Basin

Heifei Basin has experienced over 40 years of exploration, but with regard to the degree of prospecting, it is still in reconnaissance stage and there is a big disagreement in understanding. This paper uses gravity, magnetic, electric - log and seismic survey data to analyze and study comprehensively, and thus discovers a "shadow basin" in lower Jurassic. The shape and scope of original basin is resumed and presented. The basin is divided into 4 exploration plays. It is pointed out that the south of the basin will be the objective of next step exploration.
