【摘要】：表(biao)面活性(xing)劑吸附在油水界面上，使油水的(de)界面張力(li)降低，減(jian)小(xiao)粘附功，從而提高了洗(xi)油能(neng)力(li)，所(suo)以從油田提高采收率的(de)角度看，表(biao)面活性(xing)劑溶液的(de)配置與篩選(xuan)起到十分(fen)重(zhong)要作用。不同表(biao)面活性(xing)劑不僅對油水界面張力(li)降低程度不同，而且(qie)起泡性(xing)能(neng)也(ye)各有差異。

針對16種不同的(de)表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)性(xing)(xing)劑(ji)，采用(yong)改進Ross-Miles法(fa)和(he)(he)TX-500C旋轉滴界(jie)(jie)面(mian)(mian)(mian)(mian)張(zhang)(zhang)力(li)儀，從起(qi)(qi)泡性(xing)(xing)能(neng)和(he)(he)降低油水界(jie)(jie)面(mian)(mian)(mian)(mian)張(zhang)(zhang)力(li)兩(liang)個方面(mian)(mian)(mian)(mian)來篩選(xuan)出理想的(de)起(qi)(qi)泡劑(ji)。根據實(shi)際的(de)操作(zuo)和(he)(he)實(shi)驗(yan)結果，HK-MAC、KB-6等表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)性(xing)(xing)劑(ji)起(qi)(qi)泡性(xing)(xing)能(neng)強(qiang);JVR-35、2011040301等能(neng)更好地降低油水界(jie)(jie)面(mian)(mian)(mian)(mian)張(zhang)(zhang)力(li);但(dan)從表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)性(xing)(xing)劑(ji)的(de)起(qi)(qi)泡性(xing)(xing)能(neng)和(he)(he)油水界(jie)(jie)面(mian)(mian)(mian)(mian)張(zhang)(zhang)力(li)兩(liang)個方面(mian)(mian)(mian)(mian)來考慮JVR-35表(biao)(biao)面(mian)(mian)(mian)(mian)活(huo)性(xing)(xing)劑(ji)最佳。
