REAGENT TREATMENT OF THE SURFACE OF THE PETROLEUM LAYER, WITH THE USE OF A SURFACTANT COMPOSITE.(SAW)

Abstract

In the paper, the issues of oil production at the 15th petroleum well . of the supsa field and the factors
affecting its productivity are discussed. in details: watering of the bottom hole zone, high viscosity of the
extracting oil, residual oil, as well as the deposition of heavy oil components asphaltenes, resins and paraffins.
here, we recommend a reagent method for solving problems, namely: the introduction of a multifunctional
composite solution of sas [alkan-202 + sulfanol] into an oil reservoir to improve the fluidity of the oil flow and
the filtration of rock aggregates. the article presents the results of laboratory studies conducted to determine the
effect of sas on the rate of filtration of rocks. the process of moving the water-oil contact in the reservoir layer
depends on the surface properties of the rock, such as capillary wetting ability, oil and water permeability,
hydrophilicity of the rock surface, filtration rate, etc. in this regard, the introduction of the sas solution into the
formation allows us adjust, increase or decrease the rate of filtration. which provides the intensity of the flow of
oil in the plast.
we investigated the dynamics of wetting of the surface of hydrophobic rocks on quartz. the effect of sas on the
rate of filtration of collectors is shown. the filtration rate was determined from the average value, and it was
found that by mixing the composite sas mixture, the flow velocity increases. the work was conducted on the
basis of scientific contacts and cooperation, the oil academy of Azerbaijan.
