Abstract: In order to study polymer distributing law after polymer flooding and the feasibility of polymer recycle,two three-dimensional anisotropic models of 50×50×10 cm were designed.One of the models had a clapboard to simulate the polymer distribution under multi layers condition,and one model had no clapboard to simulate polymer distribution under a single oil-bearing layer.The rule of polymer adsorption post polymer flooding was studied by analyzing the gross polymer production volume and absorption volume.The results show that more than 60% of total injecting polymer has been adsorbed,where more than 90% of total adsorption is held up by high permeability or medium permeability layers,and the adsorption content gradually increases from injecting well to picking well.The research results provide favorable evidence for recycling the adsorbed polymer.
