В Таблице приведены результаты испытани предлагаемого состава в сравнени с составом по Прототипу.The invention relates to the oil and gas industry, in particular to polymer cement compositions and can be used to isolate zones of absorption and water inflow into the well, & also to restore casing tightness. Known composition containing urea nofs rmaldehyde resin, water polyacrylamide and ferric chloride i. The disadvantages of this composition. Low adhesion properties and shrinkage of the cured material. The closest to the present invention is a composition containing, urea-amino acid-furfurol resin, polyvinyl alcohol and hardener 2Q. The disadvantages of the well-known coaxinge are the low compressive strength and shrinkage of the composition. The value of the invention is an increase in compressive strength and a reduction in the reduction of the composition. This goal is achieved by haem, which is a substitute composition for insulating formations in a well, containing urea-formaldehyde-furfurol resin, polyvinyl alcohol and a hardener, additionally contains dibutyl phthalate, and as a hardener it contains a synthetic tartaric acid, a body dimension, which is a simple tweeter, also contains a synthetic tartaric acid, a dibutyl phthalate, and has a synthetic tartaric acid, and a metric will include a synthetic tartaric acid, a dibutyl phthalate, and a body hint containing a synthetic tartaric acid, and a metric will include a synthetic tartaric acid, a dibutyl phthalate, and a metric will contain a synthetic tartaric acid, a body dimension, and a metric will include a synthetic tartaric acid, a dibutyl phthalate, and a metric that contains a synthetic tartaric acid, a body dimension, a tweeter, and a synthetic hint of tartaric acid that contains synthetic tartaric acid, and contains a synthetic tartaric acid and a hardening agent that contains synthetic tartaric acid and a hint of synthetic tartaric acid; nofurfural-, for resin81, 97, 9 Polyvinyl СЯП1ФТ.1,43-5,0 Dibutyl phthalate Q, 57-2.0 Synthetic tartaric acid 0.1-2.0 Prepared as follows. Credible polyvinyl alcohol solvents are dissolved in water and a 4% aqueous solution is obtained; to this solution dibutyl phthalate is added. Gshi 1: 2,5. The resulting mixture is injected into urea urea resin and resin, and then synthetic tartaric acid is added. Composition is tested using laboratory conditions:. , .. The table shows the results of testing the proposed composition in comparison with the composition according to the Prototype.
