摘要:
A gellable composition for oil field operations and a process for accelerating the gelation of the gellable composition for shut-in well are disclosed. The composition comprises: (1) an ammonium ion donor; (2) a water soluble acrylamide-containing polymer; (3) a first crosslinking component selected from the group consisting of aldehydes and aldehyde-generating compounds; (4) a second crosslinking component selected from the group consisting of an aromatic compound and an alcohol where the aromatic compound is selected from the group consisting of phenols and acids; and (4) water.
