摘要
安参1井是胜利油田取得合肥盆地油气勘探权之后钻探的第一口区域探井,但因化石极少,更没有发现具有划时代意义的化石,因而选择K-Ar法、40Ar/39Ar法、砂岩中石英电子自旋共振(ESR)及大理岩的铅-铅等时线法测年等同位素年代学法进行安参1井的地层划分,从而准确地确定了安参1井的地层时代及划分界限,为合肥盆地基础地质的深入研究奠定了坚实的基础.
Ancan 1 was the first exploratory well drilled in the Hefei basin after Shengli Oilfield acquired the oil-gas exploration right in this area, however, due to few fossil data, especially no typical fossils to identify the ages of strata, K-Ar, Ar/Ar and electron spin resonance （ESR） for quartz in sandstone and lead-lead isochronal approaches to marble were applied to delimitation of strata encountered by the well Ancan 1, which gave precise stratigraphic ages and division boundaries for the well Ancan 1, laying a solid basis for further study of the fundamental geology of the Hefei basin
