METHOD FOR LIMITATION OF WATER INFLOW TO WELL

摘要

A method for limitation of water inflow to a well includes sequential pumping-in to the bed of two portions of polymer solution “Polikar”. Preliminarily the first portion is prepared of dissolved in fresh water polymer “Polikar” and cation-active surfactant added to the last one. Then the second portion is prepared, of polymer “Polikar” dissolved in fresh water, and non-ionic surface-active substance additionally included to the last one. The second portion is pressed in to the bed with mineralized water in volume exceeding the volume of the producing string minimum by 1.2 times. The well is left at pressure for 12-48 hours for formation of hydro-insulating screen.
