摘要： 将交替注入碱-表面活性剂-聚合物(简称ASP)和氮气时,针对泡沫的生成及稳定性影响因素开展了大量的实验研究,着重探讨在不同流速、不同压力条件下的渗流行为。实验结果表明,泡沫的形成与运移严重受流速和压力的影响,流速太大,存在严重气窜现象,流速太小,不利于泡沫在孔隙介质中的传播,压力越小,越利于形成稳定的泡沫。一旦形成泡沫,流动阻力明显增加,大大降低驱替流体的流度。氮气/ASP交替注入时,在入口端生成的泡沫可以被高粘流体驱替向远处传播。

Abstract:
A series laboratory experiments have been carried out in this paper to investigate foam behaviors during N2/ASP alternative injection, especially its flow behaviors under different flow rate and pressure conditions. Experimental results show that the formation and flow of foam were seriously affected by velocity and pressure. High flow velocity makes gas channeling happen,and low flow velocity makes the difficulty increase of foam propagating along the displacement. Low pressure is beneficial to generate stable foams. Once foam formed, its flow resistance increases and mobility decreases notably. In the process of N2/ASP alternative injection, the foam generated in the input area will propagate along porous media at the displacing of viscous fluid.
