SHEAR ACTIVATED INFLATION FLUID SYSTEM FOR INFLATABLE PACKERS

摘要

A subterranean well packer is inflated by a pumped transfer of rheotropic fluid through a tortuous flow channel into a packer sealing element expansio n chamber. The tortuous flow channel and fluid delivery pressure are coordinat ed with the fluid properties to impose sufficient fluid shear stress for inducement of a substantial phase change in said reheotrpic fluid after entr y into expanion chamber.
