TEMPERATURE SENSITIVE VISCOELASTIC WELL-TREATMENT FLUIDS |
摘要 |
<p>The present invention is directed to fracturing fluids having temperature- sensitive viscosities. The fracturing fluids may include a mixture of a hydrophobically associative polymer (HAP) and a surfactant in an aqueous medium, wherein the surfactant imparts a critical solution temperature (CST) to the fluid. The fluid is more viscous at temperatures lower than the CST as compared to temperatures above the CST.</p> |
