| 摘 要： | 对孤东油田馆上段四、五砂层组之间发育的生物标志层的特征进行了研究.这种生物组合形成于河湖相中,由于水介质条件突变,生物死亡并堆积成层.它不仅可以作为地层对比的标志,也可为解释沉积环境提供依据。

| Abstract: | Bioclasic maker bed developed between the forth and fifth sand body of the upper Guantao formation in the Gudong oilfield. The bioclastic assemblage is of fluvial-lacustrine origion. When the water body conditions changed suddenly, the organisms perished and setted down. It is not only taken as the criteria of strati graphic correlation, but also as a basis for sedimentary environment analysis. |
