地层是一切地质问题的基础,地层的划分直接影响着对盆地构造演化、沉积环境甚至对全盆地含油气远景的认识。该文从岩性、电性及地震反射特征等方面对安参1井已钻遇地层特征进行研究,初步建立了合肥盆地中生代地层层序格架,对深入认识和解剖盆地的构造演化、地层展布特征、沉积环境及含油气远景具有一定的指导意义。 Stratigraphy is the foundation of all geological problems. Stratigraphic division directly affects the understanding of tectonic evolution in the basin, sedimentary environment and even the hydrocarbon-rich prospect of the whole basin. This paper studies the stratigraphic features of Ansai-1 well from the aspects of lithology, electrical property and seismic reflection, and initially establishes the Mesozoic stratigraphic sequence framework in the Hefei Basin. It is of great significance to understand and dissect the tectonic evolution of the basin, Distribution characteristics, sedimentary environment and oil and gas prospect has a certain guiding significance.
