驱油剂在双河油砂上的静态吸附研究

Static Adsorption Research of Oil Displacement Agent on Shuanghe Oil-sands

采用静态吸附法研究了驱油剂OCS(石油磺酸盐)和HPAM(部分水解聚丙烯酰胺)在河南油田双河油砂上的吸附特性,求出了在使用浓度下的表观静态吸附量和饱和吸附量,并用Langm u ir和F reund lich公式对其吸附趋势进行了预测,发现OCS和HPAM都具有典型的单分子层的吸附规律。

Using the static adsorption method, we have studied the adsorption characteristic of OCS（mahogany petroleum sulfonates） and HPAM （partially hydrolyzed polyacrylamide amide） on the Shuanghe oil-sands of Henan oilfield, and have extracted their static adsorptive quantity under the using density and saturated adsorptive quantity. We also have carried on the forecast to its adsorption tendency with Langmuir and the Freundlich formula and have discovered that OCS and HPAM all have the representative rule of the monomolecular adsorption.
