摘　　要：总结前人研究成果和近期勘探成果，重新确立了该区石炭纪地层层序，将原小海子组解体，以其内部存在的沉积间断为界，其上划为下二叠统南闸组，其下归为上石炭统，并命名为喀拉拜勒组；将原巴楚组解体，其上部“双峰灰岩”段及泥岩段仍为下石炭统巴楚组，下部砂泥岩互层段及砂岩段（东河砂岩段）归入上泥盆统，称东河塘组，并对井下石炭系进行了横向对比。A new Carboniferous sequence is obtained based on previous studies and recent exploration results. Primary Xiaohaizi Formation is redivided Into Lower Permian Nanzha Formation and Upper Carboniferous Karabaile Formation seperated from each other by sedimentary discontinuity. Primary Bachu Formation is seperated into two parts. The upper part composed of 'bimodal' limestones and mudstones is still called Lower Carboniferous Bachu Formation, the lower part composed of sandstone and mudstone intercalations and sandstones (Donghe sandstone section) is classified into Upper Devonian Donghetang Formation. And downhole Carboniferous is correlated.
