Fluid viscosity control |
| 摘要 |
A method of treating a subterranean formation penetrated by a wellbore includes introducing a treatment fluid comprised at least a crosslinkable component, and a metal crosslinker to the subterranean formation, forming a crosslinked treatment fluid, and de-crosslinking bonds of the crosslinked treatment fluid by manipulating a pH of the treatment fluid with a pH triggering agent, wherein the pH triggering agent is an amine-precursor compound or a derivative thereof. |

1. A method of treating a subterranean formation penetrated by a wellbore, the method comprising:
introducing a treatment fluid comprised at least a crosslinkable component, and a metal crosslinker comprising a polyvalent metal ion to the subterranean formation; forming a crosslinked treatment fluid, and de-crosslinking bonds of the crosslinked treatment fluid by increasing a pH of the treatment fluid with a pH triggering agent, wherein the pH triggering agent is an amine-precursor compound or a derivative thereof. |
