摘要： 对塔里木盆地西南地区的地震和井下资料进行综合研究认为,巴楚隆起与塔中隆起之间可能存在震旦系；中。上奥陶统在塔西南坳陷南侧是否有分布,尚不清楚；下石炭统只分布在塔西南的西部；巴楚地区的卡拉沙依组与卡拉沙依剖面所定的卡拉沙依组不是同一组地层,并在此基础上提出了盆地南、北石炭系、二叠系对比意见。

Abstract: Having calibrated, correlated and comprehensively studied the seismic and downhole data from southwestem area in Tarim basin, this article shows that there might be a Sinian between Bachu uplft and Tazhong uplift; the distribution of Middle and Upper Ordovician in south side of the southwest depression of Tarim basin remains not clear; while Lower Carboniferous lies almost in its west part. Also, it is confirmed that Kalashayi formation in Bachu area is not the same one as that determined by Kalashayi profile.
