本文提出了反映四川东部嘉陵江组二段储层形成过程的系列模式，即沉积模式、成岩模式和储层分布模式。指出沉积作用、成岩作用和构造作用共同决定了储层的形成和演化，受限海台是储层发育的有利相带，溶蚀和云化作用是孔隙层形成的必要条件，构造裂缝是储层高产的重要因素。
This paper presents a series of models that reflect the formation of the second member of the Jialingjiang Formation in the eastern part of Sichuan Province, namely sedimentary model, diagenetic model and reservoir distribution model. It is pointed out that sedimentation, diagenesis and tectonism jointly determine the formation and evolution of reservoirs. The restricted seawall is a favorable facies belt for reservoir development. Erosion and cloudification are the necessary conditions for formation of the pore layer. The structural fracture is the reservoir An important factor in high yield.
