摘　　要：玉北地区位于塔里木盆地麦盖提斜坡东段,现今构造格局与西昆仑造山带、阿尔金造山带两大构造域的共同作用密切相关,整体表现为南倾的单斜,具"东西分区、上下分层"特点。发育加里东早期伸展断层、加里东中—晚期走滑断层、加里东中—晚期冲断层、加里东中—晚期滑脱型逆冲断层、海西晚期逆冲断层,构成上下两大断裂系统。玉北地区经历多期构造运动,主要遭受加里东中期—海西早期左行压扭、海西晚期挤压两期重要改造。构造演化控制岩溶缝洞型储层发育,断裂为油气垂向运移提供了良好运移通道,断垒带多期岩溶叠加期区和加里东中期Ⅰ幕岩溶发育区是油气勘探有利区。Yubei is located at the eastern Markit slope,Tarim basin.The current tectonic framework,closely related to in-teraction between western Kunlun and Aerjin tectonic domains,is typical of a south-dipping slope and characterized by east and west divisions and upper and lower layered.Five types of faults are developed,including early Caledonian exten-sional faults,middle Caledonian-late Caledonian strike-slip faults,middle Caledonian-late Caledonian detachment thrust faults,middle Caledonian-early Hercynian thrust faults and late Hercynian thrust faults, and constitute the two major fault systems. Yubei has experienced multiphase tectonic movements,and suffered sinistral compressional and torsional trans-formation in middle Caledonian-early Hercynian and extrusion transformation in late Hercynian.Tectonic evolution have controlling effect on the development of karst fractured-vuggy reservoir.The faults provide access for hydrocarbon migra-tion,the Multi-phase karstification area in faulted horst belt and the karstification area in the 1st Phase of the Middle Caledonian are favorable areas of oil and gas exploration.
