| 摘 要： | 在碳酸盐岩储层评价中，储层类型的识别与分类是其关键，而储集空间决定了储层类型。储集空间主要以沉积以后的成岩后生及表生阶段改造的次生孔隙为主。由于次生改造作用的千差万别，再加上不同期次的改造作用的叠加，使得碳酸盐岩储层的次生孔隙结构异常复杂，储集空间的复杂性也造成了储层类型的多样性。文章根据研究区块常规、成像测井资料，结合取芯、地质以及测试资料对储层类型进行识别，并应用聚类分析方法对储层进行分类。研究结果表明，储层类型主要分为孔隙型、孔洞型、裂缝型储层，并将其分为四类储层，为研究区碳酸盐岩储层评价奠定了基础。

| Abstract: | In the evaluation of carbonate reservoirs, it is critical to identify and classify the reservoir types.The reservior types are determined by the storage space of reserviors.The storage space of a reservoir is dependent on primary pores generated by the diagenesis of sedimentary rock and secondary voids due to the transformation of the rocks at later supergene stage. Because of secondary transformation is highly variable, together with the alterations of the rock formations at different stages, the secondary pore structure of carbonate reservoirs is very complex, which causes the diversity of reservoir type. To solve this problem, based on the zoning of the carbonate rocks, well imagery and logging data, combined with coring, reservoir geology and testing data, this work attempts to identify reservoir types and categorize them by clustering analysis. The results suggest that the reservoirs in the study area include porous types, vuggy types, and fractured media types, which can be divided into four categories, serving as basis for carbonate reservoir evaluation. |
