中文摘要：

塔里木盆地是中国重要的油气资源战略接替区之一,其海相碳酸盐岩油气勘探难度大,地层划分与对比的准确性与精度直接影响油气勘探各个环节工作的开展。本文对寒武—奥陶系碳酸盐岩层序地层学理论体系的应用、层序界面类型与识别标志及具代表性的层序划分方案等基础问题进行了论述,重点探讨了层序地层格架中烃源岩与岩溶型储层的预测及层序界面对于流体的输导作用,提出了塔里木盆地碳酸盐岩层序地层学研究中存在的一些关键问题,并对今后的发展趋势提出了初步设想。

英文摘要：

Tarim Basin is one of the most important strategic succeeding regions of hydrocarbon resources in China,where petroleum exploration in marine carbonate rocks is very difficult. The veracity and accuracy of stratigraphic division and comparison have directly influenced each step of petroleum exploration. The authors discuss on the application of sequence stratigraphic theory,the style and identification sign of sequence boundary and the typical sequence division scheme of Cambrian--Ordovician carbonate rocks,particalarly on the forecast of source rock and karst reservoir in sequence stratigraphic framework and the migratory effect of sequence boundary to fluid. A series of key questions about carbonate rock sequence stratigraphic research and the primary imagination of development trend in the Tarim Basin are proposed in this paper.
