FLUID DIVERSION SYSTEM FOR WELL TREATMENT OPERATIONS

摘要

A fluid diversion system for injection into a subterranean formation undergoing hydraulic fracturing operations. The fluid diversion system includes a carrier fluid comprising water; a cross-linked polymer; and a dispersion of “substantially insoluble” degradable bridging particulates in the carrier fluid. The degradable bridging particulates are exemplified by PLA, HEC, CMC, Guar gum, and/or HPS. When injected into a subterranean formation, the fluid diversion system is operative for diverting fluid for a predetermined period of time until degradation of the degradable components of the fluid diversion system restores permeability.
