摘　　要：针对稠油油藏研制封窜发泡剂OA。在保持相同的气液注入压力的情况下,优选注入方式、气液比、段塞大小和注入速度,评价油对泡沫的影响。实验结果表明,交替注入优于同时注入,气液比值优选为3时综合效果最好,段塞越大,阻力越大,注入速度优选为1mL/min。In view of heavy oil reservoir,it develops sealing foam agent OA. In the condition of the same injection pressure of gas/fluid,it optimizes the way of injection,the ratio of gas/fluid,the size of slug and the injection rate,and evaluates the influence of oil on foam. The experiment result shows that alternating injection is better than simultaneous injection;the gas/fluid ratio 3 leads to the best effect synthetically;with larger slug comes larger resistance;the best injection rate is 1ml/min.
