储层油藏动态模型及剩余油研究

Research of Reservoir Dynamic Model and Remaining Oil Distribution

经长期注水开发，储层宏观、微观参数一般都随着油藏开发程度的加大而发生有规律的变化，但不同类型的参数有各自的特征和变化规律。以胜坨油田胜二区沙二段8^3层低渗透砂岩储层为例，综合应用多学科的理论和技术，建立了储层宏观和微观动态模型，揭示了不同含水阶段油藏参数的变化规律，剩余油的形成机理、分布规律和控制因素。

Due to long-term water injection, reservoir nmcro and micro parameters may generally change regularly with the increase of reservoir development level, but different types of parameters have their own characteristics and variety. Shengtuo Oilfield Sheng II Zone Sha Ⅱ section 83rd layer low permeability sandstone reservoir is taken as example, multi-disciplinary theory and technology are comprehensively applied to establish reservoir macro and micro dynamic models, to reveal the change rules of reservoir parameters of different water-containing stages, formation mechanism of residual oil, distribution rules and control factors.
