摘　　要：塔里木盆地台盆区的构造单元划分对深入研究台盆区沉积构造演化、指导台盆区下古生界油气勘探具有重要意义。在分析了以往使用多年的塔里木盆地构造单元划分方案和有关的地质研究报告、相关地震剖面的基础上,充分利用全盆构造编图的最新成果,提出了台盆区构造单元新的划分方案。根据本方案对构造单元的边界划分依据和命名原则,将台盆区划分为10个一级构造单元,并对其中4个一级构造单元共划分出16个二级构造单元。本方案与以往方案的主要差别体现在:麦盖提斜坡升为一级构造单元,多个一、二级构造单元边界有微调整,对二级构造单元的缓坡作了新的划分。How to divide structural units of the Paleozoic platform-basin region in Tarim basin is significant to researching sedimentary and structural evolutions and guiding petroleum exploration in it. Based on the analysis of some previous division programs that have been used, relative geological research reports and available seismic profiles, and referring to the latest achievements on the structural mapping of the whole basin, a propagable division program of structural units in the platform-basin region is proposed. According to the division concept of structure boundaries and the nomenclature in this program, this platform-basin region are divided into 10 Grade- I structural units, among which 4 Grade- I units are further subdivided into 16 Grade - Ⅱ units. In comparison with previous division programs, Markit Slope is ranked from the Grade- Ⅱ up to the Grade - I and a number of structural boundaries of Grade - I units and corresponding Grade- Ⅱ units are micro-corrected. Some Grade -Ⅱ units of gentle slopes are also re-divided.
