                压裂     要求泡沫具有较长的半衰期和泡沫稳定性,对于一些特殊                  要求稳泡剂溶液具有较高的黏度,从而具有较好的携带支
                       地层,对泡沫有更高的要求,如抗油性、耐高温性等                    撑剂的能力;也要具有较低的残渣含量,这样对储层伤害
                                                                  小,避免了地层的二次污染,达到比较好的增产效果
                驱油     要求泡沫具有较好的稳定性,泡沫流体黏度大,并具有一                  要求稳泡剂可有效增加液膜的表面黏度,延长半衰期,并
                       定的抗油性                                      考虑稳泡剂与发泡剂的配伍性,以达到最佳效果,增强泡
                                                                  沫的稳定性
              洗井作业     要求泡沫流体动切力大,密度低,黏度高,并具有良好的                  要求稳泡剂溶液黏度高,液相黏度的增加可提高泡沫液膜
                       分散性及乳化性,能使其对附着在油管内、外壁、套管内                  的机械强度,使泡沫稳定性变好,但液相黏度不宜过高,
                       壁及井下工具(设备)通道上的石蜡及粘结物有较好的剥                  过高会妨碍气体在液相中的分散,也使表面活性剂分子不
