Methods for mitigating precipitation during matrix acidizing of a subterranean formation. The methods generally comprise introducing a treatment fluid into a subterranean formation. The treatment fluid comprises a chelating agent; a hydrofluoric acid source; and a stabilizing compound. The stabilizing compound has two or more quaternized amine groups. In some cases the treatment fluid further comprises alkali metal ions.

1. A method comprising: providing a treatment fluid that comprises:a chelating agent; a hydrofluoric acid source; anda stabilizing compound having two or more quaternized amine groups;introducing the treatment fluid into a subterranean formation; andexposing the stabilizing compound to dissolved aluminum and silicon in the presence of alkali metal ions in the subterranean formation to mitigate precipitation by forming an ion pair,wherein the stabilizing compound comprises a bis-quaternary ammonium compound;wherein the bis-quaternary ammonium compound has a structure of wherein R1-R6 each comprise a carbon-containing group comprising 1 to about 20 carbon atoms, R1-R6 being the same or different;wherein Z comprises a linker moiety comprising two or more atoms;wherein X is an anion;wherein Z is selected from the group consisting of —CH(R7)CH2—, —CH(OR7)CH2—, —CH(NR7R8)CH2—, —CH(R7)CH2CH2—, —CH2CH(R7)CH2—, —CH(OR7)CH2CH2—, —CH(NR7R8)CH2CH2—, —CH2CH(OR7)CH2—, and —CH2CH(NR7R8)CH2—; andwherein R7 and R8 are independently selected from the group consisting of H and a carbon-containing group comprising 1 to about 20 carbon atoms. 2. The method of claim 1, wherein the treatment fluid further comprises the alkali metal ions. 3. The method of claim 2, wherein the chelating agent comprises an alkali metal salt of the chelating agent, the treatment fluid further comprises a carrier fluid comprising an alkali metal salt, or any combination thereof. 4. The method of claim 1, wherein the chelating agent comprises an ammonium salt of the chelating agent, the treatment fluid further comprises a carrier fluid comprising an ammonium salt, or any combination thereof. 5. The method of claim 1, wherein the subterranean formation contains the alkali metal ions, the alkali metal ions not being removed from the subterranean formation before introducing the treatment fluid thereto. 6. The method of claim 1, wherein the subterranean formation contains an aluminosilicate material. 7. The method of claim 6, wherein the subterranean formation further contains about 1% to about 35% of a carbonate material. 8. A method comprising: providing a treatment fluid comprising: a chelating agent;alkali metal ions;a hydrofluoric acid source; anda stabilizing compound having two or more quaternized amine groups;introducing the treatment fluid into a subterranean formation;at least partially dissolving a surface within the subterranean formation; andexposing the stabilizing compound to dissolved aluminum and silicon in the presence of the alkali metal ions in the subterranean formation to mitigate precipitation by forming an ion pair,wherein the stabilizing compound comprises a bis-quaternary ammonium compound;wherein the bis-quaternary ammonium compound has a structure of wherein R1-R6 each comprise a carbon-containing group comprising 1 to about 20 carbon atoms, R1-R6 being the same or different;wherein Z comprises a linker moiety comprising two or more atoms;wherein X is an anion;wherein Z is selected from the group consisting of —CH(R7)CH2—, —CH(OR7)CH2—, —CH(NR7R8)CH2—, —CH(R7)CH2CH2—, —CH2CH(R7)CH2—, —CH(OR7)CH2CH2—, —CH(NR7R8)CH2CH2—, —CH2CH(OR7)CH2—, and —CH2CH(NR7R8)CH2—; andwherein R7 and R8 are independently selected from the group consisting of H and a carbon-containing group comprising 1 to about 20 carbon atoms. 9. The method of claim 8, wherein the chelating agent comprises an alkali metal salt of the chelating agent, the treatment fluid further comprises a carrier fluid comprising an alkali metal salt, or any combination thereof. 10. The method of claim 8, wherein the subterranean formation contains an aluminosilicate material. 11. A method comprising: introducing a chelating agent, a stabilizing compound having two or more quaternized amine groups, and a hydrofluoric acid source into a subterranean formation;at least partially dissolving a surface within the subterranean formation; andexposing the stabilizing compound to dissolved aluminum and silicon in the presence of alkali metal ions in the subterranean formation to mitigate precipitation by forming an ion pair,wherein the stabilizing compound comprises a bis-quaternary ammonium compound;wherein the bis-quaternary ammonium compound has a structure of wherein R1-R6 each comprise a carbon-containing group comprising 1 to about 20 carbon atoms, R1-R6 being the same or different;wherein Z comprises a linker moiety comprising two or more atoms;wherein X is an anion;wherein Z is selected from the group consisting of —CH(R7)CH2—, —CH(OR7)CH2—, —CH(NR7R8)CH2—, —CH(R7)CH2CH2—, —CH2CH(R7)CH2—, —CH(OR7)CH2CH2—, —CH(NR7R8)CH2CH2—, —CH2CH(OR7)CH2—, and —CH2CH(NR7R8)CH2—; andwherein R7 and R8 are independently selected from the group consisting of H and a carbon-containing group comprising 1 to about 20 carbon atoms. 12. The method of claim 11, wherein the chelating agent, the stabilizing compound, and the hydrofluoric acid source are combined in a treatment fluid that is introduced to the subterranean formation. 13. The method of claim 11, wherein the stabilizing compound is introduced to the subterranean formation before the chelating agent, the hydrofluoric acid source, or both. 14. The method of claim 11, wherein the subterranean formation contains an aluminosilicate material.
