Key words:hydrophobization composition, low-permeability reservoir, limination of water inflow, phase permeability.
The technology of limitation of the water supply by using hydrophobic acid compound is based on the cationic surfactant and hydrochloric acid, is recommends using on production wells started after drilling, hydraulic fracturing for process development, 1, 2 stage of development oilfield and having low water saturation.
The pilot program was developed for treatment production wells after hydraulic fracturing at the final stage of development after drilling or performing geological and technical measures, section of the reservoirs Tyumen deposits were determined.
The criteria of selecting wells indicators and wells candidates were determined and substantiated, the way to compare main geological characteristics and work parameters of wells, the effectiveness of water supply limitation was done.
