The effect of surfactants on hydrocarbon filtration by porous media

We studied the effect of a surface-active substance on the filtration of hydrocarbons by the core of a porous medium. The dependence of the flow rate of hydrocarbon filtered by the core on the pressure at constant temperature was obtained. It was established that the surface active substance effectively affects the filtration of hydrocarbons by a porous medium and increases hydrocarbon filtration by tens of percent. The use of surface-active substances to pre-treataround the filter space of an oil well allows for an increase in the well’s flow rate.
