On the basis of previous research results, a series of studies on black shales of the Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Formation in southeastern Chongqing have been carried out with thin sections and scanning electron microscopy. The results show that the pore types of black shale reservoirs in Wufeng-Longmaxi Formation in southeastern Chongqing include intergranular pore, intragranular dissolution pore, organic pore and fracture.
