ACIDIZING WITH SILANE TREATMENT TO CONTROL FINES MIGRATION IN A WELL

摘要

Methods for treating a zone of a subterranean formation penetrated by a wellbore comprising: (A) introducing an acidizing fluid into the zone of the subterranean formation; (B) forming a treatment fluid comprising: (i) a first chemical having: (a) a single epoxy group; and (b) at least one alkoxy group on a silicon atom, wherein the first chemical is water soluble or dissolves with hydrolysis in an aqueous phase; and (ii) a second chemical having an amine group, wherein the second chemical is water soluble or dissolves with hydrolysis in an aqueous phase; and (C) introducing the treatment fluid through the wellbore into the zone of the subterranean formation. In various embodiments, the treatment fluid has a viscosity of less than 5 cP measured at a shear rate of 511 sec−1.
