Analysis of the directions for improving the development systems for oil fields at the later stage

The object of research is oil fields at a late stage their development. most problematic issues in the development are formation and withdrawal residual reserves. This problem especially acute or final stage, when productivity wells decreases water cut production catastrophically increases. acceptable system such conditions use methods for increasing recovery and, first all, by injecting into reservoir. At same time, issue lack reliable information on paths movement from injection to imperfection aligning injectivity profile flow wells.
 In course study, statistically analytical were used analyze state industrial approbation tracing substantiation reagent base align inflow.
 A set reagents technological ensuring regulation process flooding have been investigated developed. It has proven that promising direction 0.1 % aqueous solution Polycar polymer together with water. all penetrates highly permeable, water-washed, intervals, contributing leveling profile, reducing surrounding productivity.
 Thanks carried out, directions means improving systems field later developed organizing targeted (selective) waterflooding deposits based high-quality comprehensive control filtration flows will ultimately contribute achieving maintaining design value reservoir pressure, preventing decrease rate decline production, obtaining sweep efficiency waterflooding, withdrawing
