Tazhong No.1 tectonic belt is an important oil and gas exploration zone in Tazhong area, the found oil and gas fields generally distribute along Tazhong No.1 tectonic belt, the development of Tazhong No.1 tectonic belt was closely related to the formation and evolution of Tazhong lower uplift. In order to reveal the activity period, formation mechanism and the formation and evolution of Tazhong No.1 tectonic belt, use the new earthquake, logging, drilling data, combining with fault related fold theory and balanced section recovery technology, analyzes the geometry and kinematics characteristics of Tazhong No.1 tectonic belt. Research results show that: 1）Tazhong No.1 tectonic belt is an anticlinal belt which was formed in the process of moving forward of the fault-bend fault in the base of Tazhong lower uplift; 2）Upper Ordovician and Siluric growth strata were identified in Tazhong lower uplift, indicating that the main activity time of Tazhong No.1 tectonic belt was in the Middle-Late Ordovician and the Silurian. 3）The tectonic activity in the east is stronger than that in the middle and west in Tazhong lower uplift, and the cumulative shortening in the east is 58.14 km, with the cumulative shortening rate is 20.84%. In conclusion, it is believed that the formation and evolution of Tazhong lower uplift was controlled by the fault-bend fault in the base which developed under the background of compressive stress, and the compressive stress continued from the late Early Ordovician to the Late Ordovician. After the Late Ordovician, Tazhong lower uplift entered into the structural broadening period. In the Early Hercynian period, the fracture activity in the base basically stopped, and Tazhong lower uplift was basically shaped.
