川东铁山、雷音铺构造嘉陵江组二段二亚段储层非均质性迥异。前者孔隙度分布不均匀且相差悬殊，储层密度及分层系数高，孔隙层呈带状分布，隔层不稳定，白云岩段所占比例大；后者孔隙层呈透镜状分布，储层密度及分层系数低于前者，隔层稳定。二者高孔隙段位于上部，孔隙层横向连通性都较好，隔层岩性均为膏质白云岩。网格化后建立的储层非均质模型显示，它们的嘉陵江组二段二亚段上部孔隙层均较发育，而下部则极不发育，铁山构造呈层状，横向连通性较透镜状分布的雷音铺构造为好。经检验与模型预测结果相吻合。
The heterogeneity of reservoirs in the second member of the second member of the Jialingjiang Formation in the Tieshan and Leiyinpu formations in East Sichuan is very different. The former has uneven distribution of porosity and great disparity, high reservoir densities and delamination coefficients, zonal distribution of pore layers, instability of interbeds and large proportion of dolomite sections. The latter is lenticularly distributed and reservoir layers The density and delamination coefficient are lower than the former, and the compartment is stable. Both the high porosity section is located in the upper part, and the horizontal connectivity in the pore layer is good. The lithology in the interbedded layers are all asphaltic dolomite. The reservoir heterogeneity model established after gridding shows that the upper two sub-layers of the Jialingjiang Formation are relatively well developed in the upper part of the sublayer, whereas the lower part is extremely undeveloped. The Tieshan structure has a layered structure with lateral connectivity more lenticular Distribution of Leiyin shop structure as well. The test and model predictions match.
