摘要： 针对靖边老庄延安组延9 油层组展开储层综合研究，依据岩心资料、铸体薄片、压汞等分析测试，在沉积相、
砂体展布的宏观控制下，结合储层岩石学特征、物性、孔隙结构等相关微观参数及有效厚度，建立储层综合分类标准，
将研究区延9 油层组各小层划分为好、一般、差3 类储层，以指导有利区块下一步的开发部署。

Abstract: A comprehensive reservoir study was carried out for the Yan 9 oil reservoir group of the Yan'an Formation in Laozhuang
in Jingbian. Based on the analysis and tests of core data, casting thin section and mercury injection, the comprehensive reservoir
classification standard was established under the macroscopic control of sedimentary facies and sand body distribution, combined
with relevant microscopic parameters such as lithology, physical properties and pore structure, and effective thickness of the
reservoir. Each small layer of the Yan 9 reservoir in the study area was classified into three types of reservoirs: good, general and
poor, to guide the next development and deployment of the favorable block.
