摘　　要：针对常规泡沫在高温、高矿化度条件下稳定性差,无法满足哈拉哈塘油藏条件的问题,研制了一种稳定性较好的泡沫凝胶体系,并对其进行了稳定性及微观结构评价。其基础配方为:1.0%纳米材料+1.0%SAV333聚合物+0.6%醛类交联剂+0.4%酚类交联剂+1.5%APG0814-CHSB(2:1)。通过显微镜分析其稳定机理,泡沫凝胶增加了泡沫液相黏度及液膜厚度,泡沫凝胶体系的液膜厚度较泡沫体系增加了32%,大幅度降低泡沫析液速率,减缓消泡速度,进而提高泡沫的稳定性。本文为泡沫凝胶提高高温、高矿化度油藏水驱后剩余油的采收率提供理论依据及指导。Aiming at the problem that conventional foam has poor stability under high temperature and high salinity conditions and cannot meet the conditions of the Halahatang oil reservoir,a foam gel system with good stability was developed,and its stability and microscopic properties were tested.Its basic formula is:1.0%nanomaterials+1.0%SAV333 polymer+0.6%aldehyde cross-linking agent+0.4%phenolic cross-linking agent+1.5%APG0814-CHSB(2:1).Through microscopic analysis of its stabilization mecha-nism,foam gel increases the foam liquid phase viscosity and liquid film thickness.The liquid film thickness of the foam gel system is 32%higher than that of the foam system,which greatly reduces the foam liquid drainage rate and slows down the defoaming speed.This in turn improves the stability of the foam.This paper provides theoretical basis and guidance for foam gel to improve the recovery rate of remaining oil after water flooding in high-temperature and high-salinity reservoirs.
