在塔里木盆地构造特征分析及地层研究的基础上 ,利用沉积盆地波动过程分析的原理和方法 ,建立了塔里木盆地典型井的剖面波动方程。研究表明 ,S/AnS ,D3/AnD3,T/AnT及J/AnJ是塔里木盆地重要的不整合 ,它们对盆地内的油气生成、运移、以及聚集、保存起控制作用。志留系与下伏地层的不整合发生在奥陶纪末 ,隆起剥蚀主要分布在塔中—巴楚及塔北地区。塔中地区剥蚀较大 ,塔中 18至塔中 5一带剥蚀量达 80 0~ 110 0m ,向南北两侧剥蚀量变小。三叠系与下伏地层的不整合发生在早二叠世末期 ,这次构造运动在塔里木盆地北部表现明显。不整合剥蚀量在塔北及塔东地区等值线近北西—南东向分布 ,由北东向南西逐渐减小 ,由提 1、草 2井区的 2 0 0 0m减至学参 1至塔中 32井区的 10 0m。巴楚地区为 10 0~ 60 0m ,从东南向北西剥蚀量增大。侏罗系与下伏地层的不整合是印支运动的结果 ,剥蚀量具有由塔中向塔东地区逐渐增大 (由 2 0 0m增加到 2 50 0m以上 ) ,巴楚隆起由南东向北西方向增大。塔北隆起大部分地区剥蚀量为 50 0~ 10 0 0m。
Based on the tectonic characteristics analysis and stratigraphic study of the Tarim Basin, the profile wave equation of the typical well in the Tarim Basin was established by using the principle and method of the analysis of the fluctuation process of the sedimentary basin. The results show that S / AnS, D3 / AnD3, T / AnT and J / AnJ are important unconformities in the Tarim Basin. They control the formation, migration, accumulation and preservation of hydrocarbons in the basin. The unconformity between the Silurian and the underlying strata occurred at the end of Ordovician. The uplift and erosion were mainly distributed in Tazhong - Bachu and Tabei areas. The denudation in Tazhong area is larger, and the denuded area in Tazhong 18 to Tazhong 5 is 80 0 ~ 110 0 m. The denudation to the north and south sides becomes smaller. The unconformity between the Triassic and the underlying strata occurred at the end of the Early Permian, and the tectonic movement was evident in the northern part of the Tarim Basin. The amount of unconsolidated denudation in the North and East Tarim areas is nearly NW-SE distribution, decreasing from NE to NW, decreasing from 2000m to 1 Tower 10 wells in 32 wells. The Bachu area is 10 0 ~ 60 0 m, and the denuded amount increases from southeast to northwest. The unconformity between the Jurassic and the underlying strata is the result of the Indosinian movement. The amount of denudation increases gradually from Tadong to Tadong (from 200m to 250m), and from the Bachu uplift from south to east Northwest increased. The denudation amount in most parts of Tabei uplift is 50 0 ~ 100 000 m.
