摘　　要：跃进二号油田为陆源碎屑岩为储集空间的油田,近年开发过程暴露出油田地下油水分布错综复杂、储层非均质性严重等问题,对储层地质特征仍需要进一步研究分析。依据岩石薄片进行储层微观非均质特征分析,包括对岩矿非均质、成岩非均质性、孔喉结构非均质性,并从断层影响、沉积微相、成岩作用三个方面分析储层非均质性的影响因素。The Yuejin No.2 oilfield is an oil field of terrigenous clastic rock. In recent years, the development process has revealed that the distribution of oil and water in the oil field is complicated and the reservoir heterogeneity is serious, and the geological characteristics of the reservoir still need further study and analysis. In this paper, according to rock slice analysis, the microscopic heterogeneity of the reservoir was investigated, including rock and mineral heterogeneity,diagenetic heterogeneity and pore throat structure heterogeneity. And the factors affecting the heterogeneity of the reservoir were analyzed from three aspects of fault influence, sedimentary microfacies and diagenesis.
