| 摘 要： | 针对强非均质油藏和大孔道稠油油藏提高采收率的需要,开展了自生气耐温冻胶泡沫调驱技术研究.冻胶泡沫是由起泡剂、聚合物和交联剂的溶液在气体作用下发泡形成的.它是以冻胶为外相的泡沫,比以水为外相的普通泡沫稳定性好.通过Ross发泡仪测定冻胶泡沫体系各组分对起泡和稳泡性能的影响,进行耐温性能评价,确.定了自生气耐温冻胶泡沫复合交联体系配方,即0.2%起泡剂AOS+0.1%复合交联体系+3 500 mg/L聚丙烯酰胺+3.45%亚硝酸钠+2.7%氯化铵+0.1%催化剂+0.1%热稳定剂.封堵实验结果表明,该体系在150 ℃下具有很好的选择性封堵能力和耐冲刷能力;并联岩心调驱实验结果表明,该体系具有明显的提高采收率效果,提高采收率为4.68%～47.73%.

| Abstract: | Technical application of authigenic gas heat-resistant gelled foam is studied for purpose of enhancing oil recovery in heavy oil reservoirs with strong heterogeneity and big channel.Gelled foam is generated with a cross-linking polymer solution con-taining a foaming agent under foaming action.Gelled foam has an external phase of gel which makes gelled foam more outstanding stability than general foam.This paper investigated the effects of different concentration of ingredients on the foaming ability and sta... |
