摘　　要：根据测井、录井及薄片等资料,研究了云安厂构造带嘉二1储层特征,认为云安厂构造带嘉二1为低孔低渗储层,在孔隙较为发育地区可以形成裂缝-孔隙型储层,储层主要受沉积、成岩与断裂三种作用影响。通过岩相学的单因素综合分析法,确定了嘉二1时期的微相环境,优选出有利构造区块。综合研究表明:位于云坪环境的大猫坪—福禄场地区与三岔坪—沙塘地区储集性能较好,其中沙塘中东部到三岔坪的中西部是嘉二1储层最发育的地区,是今后深化勘探的有利区域。T1J21 reservoir characteristics of Yun'anchang Structural Belt were studied based on some data from well logging,mud logging and thin-section analysis. It is considered that :(1) T1J21 is a low-porosity and low-permeability reservoir,and fractured-porous reservoir may be formed in a certain area with developed pore and (2) it is affected by sedimentation,diagenesis and faulting. In addition,a microfacies environment during T1J21 was determined and a favorable structural block was optimized by petrographical study. The results illustrate that the reservoir property in both Damaoping-Fuluchang and Sanchaping-Shatang areas,which are located at Yunping,is better. And the area from middle-east of Shatang to middle-west of Sanchaping is the most developed one of T1J21 reservoir,which will be a favorable zone for further exploration.
