摘要
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。
The formation of reservoir in the section Ⅱof JialingJiang Formation in East Sichuan is controlled by sedimentation, diagenetic and tectonic action. The environment of limited submarine plateau is a favourable facies belt for reservoir development. Early exposed corrosion and dolomization are necessary conditions for the formation of pore layers. A series of models which can reflect the forming mechanism,evolution and distributive laws of reservoirs are also put forward in the paper, including sedimentary models, diagenetic models and the distributive models of reservoirs. These multisided formative models are of guidance significance for the explOration, development and potentiality-tapping of gas pools in the section Ⅱof Jialingjiang Formation.
