摘要
The Tertiary high quality reservoir was mainly developed in the fine, but not coarse granular detrital rocks of eastern Kuqa depression of the Tarim basin. The reservoir evolution is reconstructed in this paper, based on a deeper analysis of tectonic, sedimentary and diagenetic process of these two rocks combined with the paleo-climate of this area. A deep analysis of sedimentary and evolution of the fine and coarse granular detrital rocks suggests that the two rocks underwent multi superimposed diagenetic effects, including syn-sedimentary, local ground water in low depth, compaction in intermediate depth, structurally fracture and burial solution, and structurally extrusion. Therefore, the present reservoir features of the two rocks vary largely. The reconstructed model for the reservoir evolution enriches the study of forming mechanism research of detrital clastic rocks.
