摘要: 介绍了一种二维可视物理模型,该模型具有可视性强的特点,可直接观察到注入水在多孔介质中的流动情况.针对辽河冷家油田储层特征及原油性质的差异,在室内建立的二维可视物理模型中进行了多油层同时注水开发、上返式开采和底水托浮式开采的模拟研究,并对比研究了不同注水方式下的开发效果及其开采机理.

Abstract: A two-dimensional physical model is described. lts inside is visible.This is a distinct feature of the model.The flow of injected water through the porous media in the model can be directly observed.In accordance with the geological characteristics of layered reservoirs and the differences of properties of the crude oil in these reservoirs of Liaohe oilfield,simulation studies on waterflooding processes in layered reservoirs were conducted by making use of the above mentioned two-dimensional visible model;these processes included concurrent waterflooding in layered reservoirs,shift of water injection from lower to upper after lower reservoirs haying been water-flooded,and waterflooding only in the lowest reservoirs to form artificial bottom water drive.The development performances of these different waterflooding modes are compared and their respective development mechanisms are studied.

Key words: wnterflooding mode, massive layered reservoirs, two-dimensional model, drive performances, development mechanism, Liaohe oilfield
