The research on basic geology has been done for Upper Carboniferous carbonate lithologic gas pools in the Huanglong Formation in the eastern Sichuan Basin.  Based on the development characteristics of terrigenous clastic deposit and the development location of suspending gravels with some psephicity,  the transgression direction and tidal depositional system distribution are deduced.  It is believed that,  two transgression channels were developed in southeast of Yunyang and northwest of Dazhou in the area,  two tidal-flat depositional systems in Chongqing-Wanzhou and southeast of Dazhou respectively were formed,  and a suit of complete type-I sequence composed of lowstand systems tract, transgressive systems tract and early highstand systems tract was developed.  Sedimentary microfacies features of each member of the Huanglong Formation were delineated finely.
