摘　　要：随着塔里木盆地油气勘探的发展,人们对盆地的构造格局有了新的认识,提出了一些新的构造单元划分方案,但没有一种方案获得广泛的认可,其重要原因是没有建立起有说服力的构造单元划分标准、依据和原则。本文根据前人有关构造单元划分惯例、构造单划分规范,结合塔里木盆地实际情况,提出了塔里木盆地构造单元划分标准、依据和原则。划分标准包括命名标准和填色、标注和界线标准,规定一级构造单元名称为隆起和坳陷;二级构造单元名称为凸起、凹陷、斜坡、冲断带和低凸起。划分依据包括界线依据和定名依据,界线依据为深大断裂、-6500m等深线、地层的尖灭线、深大断裂走向趋势线、构造体系包络线和坡折带转折端;定名依据为深大断裂上、下盘、勘探目的层和烃源岩层、构造演化、基底和构造体系,其重要程度在台盆区和前陆区有所不同。根据油气勘探实际和盆地构造演化,提出了七项构造单元划分原则。With the development of hydrocarbon exploration in Tarim basin, some new opinions to the structural framework and schemes of structural units division of Tarim basin are put forward. However, any new schemes do not acquire comprehensive acceptance, which is mainly related to the absence of convictive division standard, evi- dence and principle of structural unit. A series of new division standard, evidence and principle of structural unit for Tarim basin is established based on the routines, standard of division of structural units and real condition of Tarim basin. It comprises of the standards of nomenclature, color, label and borderlines, the first-order structural units including uplift and depression, the second-order units including rise, sag, slope, thrust belt and low rise. On one hand, dividing evidences are related to borderlines and denomination, and the types of borderlines are deep fault, -6500m contohr, trending line of deep fault, envelope line of structural system. On the other hand, the denomination evidences include deep fault, target horizon and source rock, structural evolution, basement and structural system. On the basis of the data acquired from field investigation, geophysical exploration, drilling and logging and tectonic evolution in Tarim basin, seven dividing principles of structural units are put forward.
