摘要
为了探索塔里木盆地区域构造演化对盆地内沉积相带展布和储层发育的控制,文章在综合了前人对塔里木盆地板块构造演化研究成果的基础上,深入分析了塔里木盆地周边早古生代区域地球动力学从伸展向挤压转换的时间及其所对应的盆地内部的沉积作用响应,认为古隆起的形成演化、台内相带的分异和台内台缘高能礁滩相带的展布、沉积基准面的转换、岩性岩相的突变以及盆地内奥陶系中多个不同级别不整合面的形成等均与周边的区域地球动力学环境具有密切的成因联系。受区域动力学背景所控制的盆内的这一系列沉积作用响应,对碳酸盐岩储层的发育具有重要的影响。它一方面控制了礁滩相储层的分布,同时也制约着受不整合面控制的岩溶储层的发育与分布,这为我们进一步分析和评价有利储集体的分布提供了宏观地质依据。
In order to search after the control of tectonic evolution over depositional facies and reservoir development in Tarim Basin,the geodynamic reversion from pull-apart to convergence surrounding the Tarim Plate and its sedimentary response in the Basin have been discussed in detail on the basis of the knowledge of the tectonic evolution of Tarim Basin.It has been considered that the formation of paleo-uplifts,migration of facies,distribution of reef and bank zones with high energy condition,reversion of base level from fall to rise,lithological change from dolomite to limestone and occurrence of unconformable surfaces in different orders are closely related to the geodynamic environment surrounding the Basin.These sedimentary responses to the geodynamic reversion,on one hand,control the distribution of reef and bank reservoirs and,on the other,restrict the development and distribution of karst reservoir under the unconformable surfaces,which provides us with geological basis for predicting and evaluating favorite reservoirs.
