Abstract
An oil reservoir is simulated by a model composed of two rectangular glass plates. The space between the plates is filled with glass chips of the similar chemical composition as the plates have. The model allows studying fluid flow in the spaced dipole array representing two wells located symmetrically relative to a certain center. The wells are simulated by holes drilled in the upper plate. The experimentation aimed to assess potential oil recovery enhancement in case of using GBK-F composition. The dependences of fluid flow rate on time in the pumping well, and on the water percentage in the overall fluid volume are obtained. The influence of the intermission in the fluid flow on the oil pattern in the reservoir after treatment with GBK-F composition is analyzed. The efficiency of the reagent is proved.
