oil and gas production. SUBSTANCE: composition consists of, wt parts: cement 100, cross-linked acryl polymer 0.15-0.35, and water 50. Polymer is capable of absorbing water or water solutions in amounts by 100 to 1000 times (depending on polymer type) exceeding own mass of polymer, which water is retained by polymer even under pressure. EFFECT: reduced hardening time and increased thixotropic properties of composition. 1 tbl
