KILL FLUID FOR OIL FIELD OPERATIONS

摘要

KILL FLUID FOR OIL FIELD OPERATIONSABSTRACTA flowing crosslinked polymer gel is employed as a kill fluidor as an additive to a kill fluid in a process for preventing theintrusion of formation fluid into a wellbore while minimizingwellbore fluid leakoff in the formation during conventional oilfield operations in the wellbore. The gel comprises an acarboxylate-containing polymer and a chromic carboxylatecrosslinking agent.
