| 摘要 |
The present invention provides a method of temporarily plugging or sealing a subterranean formation by introducing a rapidly viscosifying liquid hydrocarbon into the formation. The method is accomplished by admixing a first component comprising an alkyl orthophosphate acid ester and an alkali metal hydroxide present in an amount sufficient to at least partially neutralize said ester and a second component comprising an amine complex resulting from the reaction of an aqueous source of aluminum or ferric ions and a C8-C18 surface active amine in the presence of a water miscible organic solvent with the liquid hydrocarbon. The mixture rapidly viscosifies to a level sufficient to temporarily plug or seal a subterranean formation or wellbore into which it is introduced.
