| 摘 要： | 依据2D和3D地震资料解释及钻井分层数据得到的不同时代地层的残余厚度图和现今埋深图,在对主要构造不整合面剥蚀量恢复和去压实校正的基础上,采用古构造、古地貌恢复方法,利用盆地模拟软件(PetroMod10)计算了不同地层的在不同构造时期的古埋深和古厚度,系统深入研究了巴楚-麦盖提地区古构造演化历史,阐明了巴楚隆起与和田古隆起构造演化关系及迁移规律,结合奥陶系岩溶储层发育特征,探讨了古隆起演化与岩溶储层发育之间关系,建立了岩溶储层发育的构造演化模式,预测了奥陶系有利岩溶储层分布地区.结果表明:巴楚-麦盖提地区古构造演化经历了加里东期、海西期、印支-燕山期和喜山期等4个构造旋回阶段;不同时期古构造面貌受控于不同构造期的区域构造应力场变化,巴楚隆起是海西早期开始发育,显现出隆起的雏形,到喜山中期开始大幅度隆升,并最终定型.构造演化经历了二个阶段,即海西运动的隆起形成和喜山运动强烈隆升改造阶段,隆起位置迁移不明显,主要表现在隆起规模上的变化.而和田古隆起则是在加里东期-海西期发育的一个大型古隆起,现今呈现为一个向南倾斜的大型麦盖提斜坡带;构造演化经历了早加里东运动雏形形成、加里东中期-海西早期运动持续隆升、海西运动中晚期的沉降埋藏、印支-喜马拉雅运动期的掀斜消失等四个阶段,且古隆起位置在平面上发生了明显逆时针方向的迁移.受和田古隆起构造演化的控制,奥陶系发育了加里东中期、晚期和海西早期等三期风化壳岩溶,其中以海西早期岩溶最发育;玉北地区遭受了三期构造抬升剥蚀,为三期岩溶的叠置区,是巴楚-麦盖提地区岩溶储层发育的最有利地区.

| Abstract: | Basd on the residual thickness map and present buried depth map of different strata interpreted from 2D and 3D seismic data and drilling data, after recovery of erosion amounts of main structural uncomformity surface and strata compaction correction, the paleo-structure, paleogeomorphologic restoration method and basin modeling software are employed to calculate the paleo-buried depth and the thickness of different formations during different tectonic periods. This paper also systematically studies on the tectonic evolution history in Bachu-Markit region, and illustrates tectonic evolution and migration of the Bachu and Hetian ancient uplift. The Ordovician karst reservoir is characterized, and its relation to ancient uplift evolution is discussed. Tectonic evolution model of the development of karst reservoir is established to forecast the favorable distribution area for Ordovician karst reservoir. The results show that Bach-Markit ancient tectonic experienced four stages of tectonic cycle, including Caledonian stage, Hercynian stage, Indosinian-Yanshan stage and Himalayan stage; tectonic appearance is controlled by the changes of regional tectonic stress field of different geologic period, Bachu uplift began to develop in the Early Hercynian and form the prototype of the uplift. Until to the Himalayan it substantially uplifted, and finally came into its present shape. The structural evolution experienced two stages, namely the uplift formation by the stage Hercynian Movement and the strong transformation by the stage Himalayan Movement, but the migration of uplift position is subtle, which appears as the change of uplift scale. However, the Hetian ancient uplift is a large ancient uplift which developed in Caledonian-Hercynian, now appears as a large slope belt named as Markit tilted to the south; The structural evolution experienced three stages, including the formation of embyro during the stage Hercynian Movement and the Continued uplift stage in Himalayan Movement, the settlement burial stage in Middle-Late Hercynian Movement and the tilt transformation and extinction stage during Himalayan Movement. The position of the ancient uplift obviously changed in the plane by moving counterclockwise. Being controlled by the tectonic evolution of Hetian ancient uplift, the Ordovician developed three stages about weathered crust of karst, including the Middle Caledonian, the Late Caledonian and the Early Hercynian, among which karst in Early Hercynian was the most developed; And the region of Yubei, suffered three stages of structural tectonic uplift, was the overlapped area owning three stage of Karst, and therefore is proved to be the most favorable area of the development of the karst reservoir in Bachu-Markit. |
