FIELD: oil industry.
SUBSTANCE: inventions group relates to compositions and applications methods in oil deposits.
In particular, the present invention relates to novel packages formed from polymer that, when injected into an oil well, provide controlled transformation characteristics and delayed self-linking with each other in fossiliferous bed conditions to obtain strong, elastic materials from a gel mass. Compositions contain polymer, collecting agents and optionally additives used in the re-crosslinking stage, uniformly distributed among the initial gel particles. Both swelling and re-crosslinking are proportionally controlled through the compositions, which must be controlled to provide functional dispersion and subsequent self-crosslinking under various fossiliferous bed conditions.
EFFECT: water seepage decrease.
