Abstract选择某商品阴离子起泡剂用于胜利孤岛油田渤21块稠油油藏的热(85℃)氮气泡沫驱。在25℃测定了泡沫体积和半衰期及长填砂管模型中的阻力因子,确定气液比应在0.5~1.0范围,最佳值为0.5,起泡剂溶液浓度应在0.3%-0.5%,最佳值为0.3%。在渗透率1.91时、用目的油藏油井原油(20℃、85℃密度分别为0.9793和0.9377g/cm^3)饱和的长管模型上,氮气泡沫驱采收率为41.6%,比热水驱采收率高21.3%;在注入初期压差下降之后,注泡沫压差持续上升。在饱和同一原油、渗透率分别为5.59和1.02心的并联双长管模型上,氮气泡沫驱的采收率分别为69.8%和58.3%,平均值63.8%,而在5.60和1.11时的饱和原油并联双长管模型上,热水驱的采收率分别为43.3%和13.8%,平均值32.6%;压差曲线表明氮气泡沫改善波及体积的效果更好。图8表4参6。
