| 摘 要： | 寒武纪—奥陶纪塔里木盆地经历了4种不同类型的碳酸盐岩台地结构型式的演变。不同台地区带的碳酸盐岩层序结构特征显著不同,柯坪地区寒武系—奥陶系为一套碳酸盐岩为主的地层,发育7种不同特征的碳酸盐岩层序构型。库鲁克塔格地区层序总体表现为半深海—深海盆地相背景下的海底扇沉积。相带和层序界面对储层发育具有重要影响,不同级别的层序界面对其下碳酸盐岩储层的发育具有重要的控制作用,并对埋藏条件下的流体具有输导作用。流体对埋藏岩溶型储层的形成具有重要的改造作用,风化壳岩溶型储层受风化淋滤带和层序界面的控制,白云岩储层和礁滩型储层主要受沉积相和成岩相控制。

| Abstract: | Tarim Basin goes through the evolution of four different carbonate platform structure types.The structure characteristics of carbonate sequences have distinct diversities in different zones.A set of carbonate strata is developed in Cambrian-Ordovician in Keping area and could be divided into 7 kinds of carbonate sequence constituting patterns,while sequence in Kuluketage area mainly is sea floor fan deposition in half deep-sea to deep-sea background.Phase belt and sequence boundary have important impact on reservoir development,and sequence boundaries with different scales have controlled the development of carbonate reservoir under these boundaries and have transportation function on fluid under burial conditions.Fluid has reconstructed the formation of burial karst reservoir,and sequence boundary and weathering-leaching zone have controlled the development of weathering crust karst reservoir.Dolomite reservoir and reef flat reservoir are controlled by sedimentary facies and diagenetic facies. |

| Keywords: | Tarim Basin platform structure sequence constituting pattern tract system karst reservoir |
