Annotation:

Recently, there exist a lot of industrially used polymer compositions used for repair and insulation works, water influx control and oil recovery enhancement. One of the promising areas of these problems solution is using polymer hydrogels, which are actively used in the oil and gas industry.

A repair-insulation composition based on domestic raw materials has been developed, which is a copolymer based on acrylates in the form of a hydrogel, which allows for simultaneous and/or sequential work to eliminate several complications in the well, such as behind-the-casing flows, leaks in the production column and alignment of the injectivity profile.
