地层时代的研究是石油地质研究的基础。文章详细分析研究了宝石一井第三纪地层古生物、岩性和电性等资料,并与区域资料对比,论证了新钻遇地层的地质时代及沉积环境。尤其是对平湖组以下地层时代的认定,完善了东海西湖凹陷新生代地层层序,对石油资源评价将产生重大影响。

Research of the geologic time of strata is the basis of petroleum geology study. This paper analyzes the fossil, lithography, logging and so on in detail, correlating with regional materials, and points out the geological age and paleosedimentary environments of a stratum which is drilled first time, and eventually establish the stratigraphic sequence of Tertiary of Baoshi-1 Well.
