Preliminary Research of Stratigraphic Sequence and Paleosedimentary Environments of Tertiary System of Baoshi-1 Well in the East China Sea

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.
