METHOD FOR SELECTIVE INSULATION OF CONES OF INFLOW OF MINERALIZED STRATAL WATER OF CALCIUM CHLORIDE ûMAGNESIUM CHLORIDE TYPE

摘要

Method for selective insulation of cones of inflow of mineralized stratal water of calcium chloride ûmagnesium chloride type includes termination of well to get static pressure, injecting to pipe or annular space of well of blocking reagent solution, this interacts with the waters named, with pressing it to stratum, with soaking solution of blocking reagent in stratum till its complete flowing over large contact area stratal water û gas or stratal water- oil, till formation in stratal conditions of impermeable layer of blocking material, development of well. Before injecting blocking reagent to well one supplies solution of potassium chloride with concentration 0.2 û 5 mass % to the well. Asblocking reagent one uses water solution of carbonic acid salts and ammonium polyphosphates in arbitrary ratio between those within 1:100 and with total concentration within solubility of those.
