摘　　要：剩余油研究是高含水油田面临的重大课题 ,是实现“稳油控水”目标的重要手段。深入分析了地质条件和开发条件对剩余油形成的影响机理 ,认为 ,地质条件 (储层非均质性 )是剩余油形成最主要的控制因素 ,并从宏观和微观两个层次剖析了储层非均质性对剩余油形成的控制作用。地质条件是客观的、内在的主要矛盾 ;开发条件是主观的、外在的次要矛盾。二者相互作用、相互影响 ,加剧了对剩余油的认识难度。It is a very important task to study remaining oil in high water-cut stage,which is a very important means for the aim of 'maintaining the oil production rate and controlling water producing'.Based on thorough analysis of effect mechanism of geology condintions and development conditions for forming of remaining oil,the paper thinks that geology conditions(reservoir heterogeneity)is the primary controlling factor in forming remaining oil.And the paper analyzes controlling function of reservoir heterogeneity during forming of remaining oil from macro level and microscopic level.Geology conditions are impersonal,inherent,mostly antinomy;development conditions are subjective,extrinsic,subordinative antinomy.The two factors function and affect each other,which increase recognization difficulty of remaining oil.
