Adsorption Research of a Polymer on Oil Sands in Xinjiang Conglomerate Reservoir

Abstract:

In the process of polymer flooding in porous media, polymer was detained because of interactions between surface adsorption and polymer molecules, and this could lead to negative effects on oil displacement. For polymer static adsorption in Xinjiang conglomerate reservoir, both of the HPLC analysis and Langmuir isothermal method were adopted to study on the rules. Results have showed that the adsorption process could be divided into 3 stages: rapid growth, slow growth and stable state. The adsorption of polymer KA on oil sands is in line with the Langmuir isotherm law. The adsorption amount is different for polymer KA on four types of oil sands. For equilibrium adsorption, the maximum value is from argillaceous sandstone, followed by conglomeratic sandstone. The third is argillaceous gravel, and the minimum is sand gravel. Adsorption equation analysis is consistent with the experimental principle statement.
