摘　　要：用静态和动态吸附方法研究了三元复合驱油体系中各个化学剂在地层温度（６８℃）下的吸附损耗。复合体系与单一体系相比，Ｎａ＿２ＣＯ＿３和ＯＰ－１０的吸附量较小，而３５３０Ｓ的较大。在复合体系中，Ｎａ＿２ＣＯ＿３、ＯＰ－１０、３５３０Ｓ的静吸附量分别为１．３３、２．４、０．２１５ｍｇ／ｇ油砂，动吸附量分别为０．６７、０．２４、０．０５５ｍｇ／ｇ油砂。The 48 hrs static adsorption on reservoir sand of Gudong Oil Field,Shengli, from A(alkaline)/S (surfactant)/p (polymer) flooding solutins for Na_2CO_3 and OP-10 is lower and for HPAM 3530S is higher than that from single solutions of these chemcals. The dynamic adsorption of OP-10 from a ASP solution in sandpack flow tests is lower than its static adsorption. The static adsorption of Na_2CO_3, OP-10 and 3530S amounts to 1.33 , 2. 4 and 0. 215mg/g sand,respectively,and the dynamic adsorption (and retention, or loss of these chemicals in sandpack flow tests-to 0. 67,0.24 and 0. 055 mg/g sand, respectively(the ASP solution contains 1.5% A, 0. 4.0% S and 0.1% P). All measurements are porformed at reservoir temperature 68℃.
