(GuYingfan,Liu Chun,Shi Bin, Wu Jinghong, Zhou Chunhui)

Aquiclude of the second confined aquifer group (Ad2)

Aquiclude of the third confined aquifer group (Ad3-1)

Aquitard of the third confined aquifer group (Ad3-2)

Semi-consolidated formation (G)

    We analyzed the porosity and entropy probability of each aquifer which were obtained by PCAS identification analysis and found that in the second confined aquifer group the porosity was the largest, the probability entropy was the largest, and the pore heterogeneity was the highest.
