Abstract:

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.
