摘要: 卡塔克隆起位于塔里木盆地中部的沙漠腹地,是加里东中期形成的继承性古隆起。研究认为鹰山组风化壳岩溶是加里东中期构造运动时发育、在后期构造变形中得到加强的产物,分布广泛,溶洞和裂缝发育;钻井揭示岩溶储层发育区主要分布在古地貌及今构造的高部位和斜坡部位,与北东向调节断裂关系密切。风化壳岩溶储层受控于加里东中期栺幕古地貌及后期的构造变形。综合以上分析,并结合卡1区块鹰山组处于古地貌高部位、构造变形强烈、成藏条件有利,认为卡1区块勘探突破重点要加强断裂精细解释和储层识别。Abstract: The Katake Uplift locates in the central desert of the Tarim Basin.It is an inherited palaeo-uplift formed during the middle Caledonian.The widespread karst weathering crusts of the YingshanFormation generated during the middle Caledonian tectonic movement,and strengthened during the lat-ter tectonic evolutions.Caves and fissures generated in the crusts.Drillings have indicated that the karstweathering crust reservoirs mainly distribute in the higher part and the slope of paleogeomorphology andpresent structures,closely related to NE oriented adjusting faults.The reservoirs are controlled by thepaleogeomorphology of Phase-Ⅰ,the middle Caledonian as well as the latter tectonic deformations.TheYingshan Formation of Ka1 region locates in the higher part of paleogeomorphology.It has experiencedstrong tectonic deformation and is favorable for accumulation.The key for exploration in Kal regionshould be fault accurate interpretation and reservoir identification.
