摘要
///In this paper, the authors divide the tectonic evolution of Tazhong area into three periods: the late middle-Caledonian cycle period, the late Caledonian kinematic period to the early Hercynian kinematic period and the Permian period. Through this tectonic evolution, it was identified tree types of reservoirs in Ordovician: the strike-slip faults-related paleocarst collapse reservoirs, the synsedimentary reverse faults-related inter-platform beaches reservoirs of Lianglitage Formation and the igneous rock activity-related reservoirs. Carbonate high-quality reservoirs were formed by tectonic activity. These three types’ reservoirs were different performances of different tectonic activity. They developed with the time and overlapped in the space. They were influenced with each other, which presented a relative independent carbonate paleokarst-fracture-cave system and indicated an important significance for exploration.
