蒸汽驱低压比例物理模型改变注采井网试验

Experiment of changing injection production pattern with low pressure scaled physical model of steam drive production

为了改变注采井网关系，在蒸汽驱高压比例物理模型和蒸汽驱真空比例物理模型基础上，建立了蒸汽驱低压比例物理模型。利用试验温场图，可明显地观察到蒸汽驱油的宏观过程，为研究蒸汽驱工艺机理提供了较完善的物理模拟方法。

In order to change injection production pattern, on the basis of high pressure and vaccum scaled physical models of steam drive production, low pressure scaled physical model has been set up. Through test temperature diagram, the macroprocess of steam flooding can be watched clearly. This method provides a better physical modelling method for studying of technological mechanism of steam drive production.
