塔里木盆地北部坳陷阿瓦提凹陷三叠系划分对比

THE CLASSIFICATION AND CORRELATION OF TRIASSIC IN AVATI DEPRESSION,NORTH DEPRESSION,TARIM BASIN

阿瓦提凹陷三叠系沉积厚度大、地层对比精度低,已成为制约该区勘探的重要因素之一.文章从岩性、电性、古生物等方面对该凹陷三叠系划分对比进行了探讨,建立了阿瓦提凹陷三叠系的划分数据表.

The Triassic of Avail depression in the Tarim basin is very thick and the precision of strailgraphic correlation is very low. This reason is one of the important reasons that restrict the exploration in this area.This paper discussed the classification and correlation of Triassic in Avati depression by researching the characters of lithology electricity and fossils.And then, we set up the data of Triassic strata in the Avail depression.
