摘要:

三元复合驱作为大庆油田新的开发技术即将进入规模推广阶段。注入三元复合剂后,储层的物理性质、流体分布形式发生了改变,测井响应特征随之也发生了变化,原有的水驱开发水淹层测井定性、定量解释方法已经不再完全适应注三元复合剂储层测井解释。利用岩石物理实验,分析了三元复合驱条件下储层电学、声学、核磁共振等特性的变化规律。结合密闭取心井资料,提出了三元复合驱储层受效判别方法和三元驱后剩余油饱和度计算模型,为三元复合驱后水淹层测井解释提供依据。

Abstract:

ASP flooding in Daqing Oilfield is a new technique for oil development and will enter the popularized stage of the commercial scale. The injection of ASP compound impregnant can change the physical properties of reservoir and fluid distribution, which can result in the change of log response characteristics of reservoirs. The former logging qualitative and quantitative interpretation method for water flooding is no longer suitable for the log interpretation of ASP flooding layer. On the basis of reservoir petrophysical experiment, the characteristics of electricity, acoustics and nuclear magnetic resonance of the ASP flooding reservoirs were analyzed. The discriminate measures for ASP flooding reservoir and new calculation model for remaining-oil saturation were proposed in combination of sealing core drilling information. The calculation can provide the basis for the log interpretation of water-flooded zone in the ASP flooding reservoirs.

Key words: ASP flooding reservoir, water-flooded zone, remaining-oil saturation; , petrophysical experiment, logging interpretation method, calculation model
