Influence of layered NONUNIFORMITY OF THE RESERVOIR ON THE PARAMETERS OF EXTRACTION AT NON-ISOTHERMAL WATER-OIL DISPLACEMENT
Improvement and creation of essentially new highly effective technologies of oil refining require the deep analysis of the complex mechanisms of intra sheeted processes. Influence on the results of production of the layers at non-isothermal filtration of layered heterogeneity of the collectors on permeability is shown. Many oil fields typically contain paraffinic and asphaltene components. At the fields of high-wax oils with a saturation temperature of the paraffin close to the reservoir temperature, a small reduction can lead to crystallization of paraffin, cooling and plugging of steam channels. At the fields of highly viscous and waxy crude oil the proportion of low permeability formations, exposed primarily to temperature effects, i. e., cooling by injecting cold water in the range from 0.01 to 0.08 µm2, sometimes up to 40 %.
