Methods plugging of a permeable Zone within a wellbore, using a composition comprising a sealing material and a reduced amount of Cement cross-linking

摘要

A method of maintaining a Well Hole, which comprises preparing a sealing material composition which comprises a cross-linking Agent, a entrecruzador, a Fluid Loss Control Additive and Water, place the Sealing composition on a permeable Zone in the hole and Shaft To Forge the Sealant composition.A method of maintaining a Well Hole, which comprises preparing a composition Gasket material, through the combination of a cross-linking Agent, a entrecruzador, a Fluid Loss Control Additive, Water and cementWhere a quantity of Cement is reduced to an amount that is effective to increase the gelation time of the Sealing composition to more than or equal to about 4 hours when the Sealing composition is exposed to Ambient temperature in the Hole Well, to place the composi ING on a permeable Zone Sealing The Hole HoleAnd Stop Sealing gel composition.
