METHOD OF HYDRAULIC FRACTURING WITH CONTROLLED PROPERTIES OF FIXING AGENT

摘要

A method of hydraulic fracturing with controlled properties of fixing agent wherein as fixing agent one uses foamed polyurethane that comprises hematite powder mass and polymer, and after implementation of hydraulic fracturing one forms magnetic field with needed power in the perforation interval. The content of soluble foamed polyurethane is 3-5 % and content of particles of magneto-active material is 30-35 % of the total volume of the fixing agent, and as magneto-active material one uses ferrous particles of milled hematite.
