在钻井层位标定的基础上,系统解释塔里木盆地西南部(简称塔西南)典型地震剖面,建立区域性的地质格架剖面,进而恢复各构造时期的剥蚀厚度,并编制寒武系盐下白云岩各时期古构造平面形态图,以分析早古生代晚期古隆起的空间展布、形成演化以及迁移规律。研究表明:早古生代晚期,塔里木盆地存在1个广布塔西南地区、统一的区域性古隆起,称之为塔里木西南部古隆起。前人所提出的“塔西南古隆起”和“和田古隆起”不是两个独立的古隆起,而是本次所识别出古隆起的时空迁移演化的结果。该古隆起始于中奥陶世末;晚奥陶世古隆起初具规模、幅度增大;志留纪时期古隆起稳定隆升,隆起范围快速向东部扩大,皮山—和田等区域成为古隆起的一部分,其构造高部位迁移到皮山—和田地区;泥盆纪古隆起开始逐渐缩小,范围仅限于塔里木盆地南部的皮山—和田一带;石炭纪古隆起成为水下隆起,古隆起逐渐消亡。塔里木盆地西南部古隆起属于早古生代晚期塔西南前陆盆地的前缘隆起,其形成演化与塔里木盆地南部西昆仑早古生代造山作用有关。塔里木盆地西南部古隆起从塔西南的西北部迁移到南部的皮山—和田一带,表明西昆仑早古生代造山作用从中奥陶世末开始于西段,呈“剪刀式”自西向东发展。古隆起的迁移演化控制了塔西南地区中奥陶世末、晚奥陶世末和中泥盆世末3期不整合的发育和不整合之下风化壳溶蚀缝洞储集层的空间分布,而古隆起构造高部位的迁移对风化壳溶蚀缝洞储集层的发育也具有重要的控制作用。

Based on well horizon calibration, the typical seismic profiles in southwestern Tarim Basin were interpreted systematically, regional geological sections were established, and the regional denudation thickness of each tectonic period was restored. On this basis, the plane morphology maps of ancient structures of the Cambrian pre-salt dolomites in different periods were compiled, and the spatial distribution, development, evolution and migration of paleo-uplift in the late Early Paleozoic were analyzed. In the late Early Paleozoic, there existed a unified regional paleo-uplift widely distributed in southwestern Tarim Basin, which is called the southwestern Tarim plaeo-uplift. The “Tarim SW paleo-uplift” and “Hotan paleo-uplift” proposed in previous literatures are not independent, but the result of the spatio-temporal migration and evolution of the southwestern Tarim paleo-uplift identified in this paper. The southwestern Tarim paleo-uplift emerged at the end of Middle Ordovician, and took its initial shape with increased amplitude in the Late Ordovician. During the Silurian, the southwestern Tarim paleo-uplift rose steadily and expanded rapidly to the east, incorporating Pishan-Hotan and other areas, with the structural high locating in the Pishan-Hotan area. During the Devonian, the southwestern Tarim paleo-uplift began to shrink gradually, to a limited range in the Pishan-Hotan area in the southern part of the basin. During the Carboniferous, the southwestern Tarim paleo-uplift became an underwater uplift, that is, the paleo-uplift gradually died out. The southwestern Tarim paleo-uplift belongs to the forebulge of the southwestern Tarim foreland basin in the late Early Paleozoic, and its formation and evolution are related to the early Paleozoic orogeny of the West Kunlun orogenic belt in the south of the Tarim Basin. The migration of the southwestern Tarim paleo-uplift from the northwestern part of the southwestern Tarim Basin to the Pishan-Hotan area indicates the early Paleozoic orogenic process of the West Kunlun orogenic belt, which started in the western section at the end of Middle Ordovician and extended from west to east in a “scissor” style. The migration and evolution of the southwestern Tarim paleo-uplift controlled the development of unconformities at the end of Middle Ordovician, the end of Late Ordovician, and the end of Middle Devonian, and the spatial distribution of dissolved fracture-cave reservoirs in weathered crust below the unconformities in the southwest of Tarim Basin. The migration of the structural high of the southwestern Tarim paleo-uplift also played an important role in controlling the development of dissolved fracture-cave reservoirs in weathered crust.
