| 摘 要： | 微体化石在解决地层的归属问题上发挥了重大作用,根据新发现的几丁虫将苏泰103井的"上震旦统陡山沱组"、都4井的"中下侏罗统象山群"、葛9井的"葛村组"地层修改归属于志留系,纠正了以前的错误地质结论。在草9井的钻进过程中,根据孢粉化石确定已钻至浦口组,推测油气目的层已钻过或缺失,提前473.03m终孔,节省了钻井费用,创造了无形产值。

| Abstract: | Palynology has played a major role in resolving biostratigraphic issues. For example, the age of the upper Sinian Doushantwo Formation of the drill core Su-Tai 103, the Lower Jurassic Xiangshan Group of the drill core Du 4, the Gecun Formation of the drill core Ge 9 has been constrained by microfossils, and incorrect biostratigraphic assignment of these units has been rectified. In the drill core Cao 9, fossil pollens have been used to determine that the drill core reached the Pukou Formation and that the h... |
