摘要： The invention provides a method. The method injects into a wellbore, a fluid comprising at least one of an acrylamide polymer and an acrylamide copolymer, and at least one of an oxidizing agent and a radical initiator; and allows viscosity of the fluid to increase for a first period of time; and subsequently, allows viscosity of the fluid to decrease for a second period of time. In a further aspect the invention provides a fluid for use in a well within a subterranean formation penetrated by a wellbore. The fluid is in a first embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein concentration of the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity. The fluid is in a second embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity.

摘要： A method of treating a subterranean formation penetrated by a wellbore utilizes a treating fluid formed from an aqueous solution of a water-soluble polymer. The treating fluid further contains a crosslinking agent and an optional delayed release alkaline additive. The delayed release alkaline additive may be at least one of urea, a urea derivative, a solid alkaline earth metal carbonate, a solid alkaline earth metal oxide and combinations of these. The treating fluid further includes an acidic pH adjusting agent used in an amount to provide the treating fluid with a pH of less than about 5. The treating fluid is then introduced into the formation.
