Environmentally benign viscous well treating fluids and methods |
摘要 |
Environmentally safe viscous well treating fluids and methods are provided by the present invention. The treating fluids are basically comprised of water, a viscosity producing polymer, a boron cross-linking agent for cross-linking the polymer, and a delayed cross-link delinker that chelates the boron and breaks the treating fluid into a low viscosity fluid selected from polysuccinamide and polyaspartic acid.
