| 摘 要： | 对研究区嘉陵江组沉积背景认识的基础上，通过岩心观察、岩石薄片确定了不同类型的储集岩和储集空间，得出本地区储层岩石类型和储渗空间类型均多样化的特点。从成因角度识别出来了溶蚀孔隙型储层、膏溶孔洞型储层、裂缝型储层等三类储层。研究不同类型储层的孔、渗特征及关系表明，溶蚀孔隙型储层物性要优于膏溶孔洞型储层，而溶蚀孔隙型储层中的颗粒云岩溶蚀孔隙型储层物性最好、颗粒灰岩溶蚀孔隙型物性其次、粉晶云岩溶蚀孔隙型储层物性最差，其原因是不同储层受沉积环境和成岩作用控制和影响。

| Abstract: | This paper deals with reservoir rock types and their accumulation spaces in the Triassic Jialingjiang Formation in Luzhou uplift based on observation the drilling core and petrographic thin section. The reservoir may be divided into dissolved-porosity, anhydrite-dissolved and fracture types. The study of porosity and permeability for the different reservoir types indicates that features the reservoir are controlled by sedimentary environment and diagenesis, and that physical property of the dissolved-porosity reservoir is better than that of anhydrite-dissolved reservoir, while the physical property of the grain dolostone dissolved-porosity reservoir is the best. |
