COMPOSITION FOR CONTROLLING WORKING OF A PETROLEUM DEPOSIT Russian patent published in 1996 - IPC

FIELD: mining industry. SUBSTANCE: composition contains 0.005-0.8 wt % polyacrylamide, 0.033-2.0 wt % organometallic siloxane (a joiner), the rest being water. As an organometallic siloxane the following compounds are used: organotitanic siloxanes marked AKOR B-100, organoaluminium siloxanes marked Petrosil, and other all having polar linkage formed by interaction of the polyvalent metal chlorides with alkylsiloxanes and easily cleaved by water in the presence of an acid, for instance following the reaction leading to formation of a hydroxyalkylsiloxane, a polyvalent cation, metal-containing hydroxyalkylsiloxanes, an alcohol, and hydrochloric acid, which catalyzes this reaction. The cross-linking of polyacrylamide is accomplished by both a polyvalent cation (titanium, aluminium ions) and an organosilicon compound containing a polyvalent metal. EFFECT: new composition obtained. 1 tbl
