摘要： The present invention relates to methods useful during sand control operations and, more particularly, to using water-soluble relative permeability modifiers that are useful for controlling fluid loss during sand control operations. In one embodiment, the present invention provides a method of providing fluid loss control during sand control operations comprising introducing a fluid that comprises a water-soluble relative permeability modifier into a well bore; and stabilizing unconsolidated formation particulates in a section of a subterranean formation penetrated by the well bore. In other embodiments, the present invention provides methods of providing fluid loss control during sand control operations and methods of reducing fluid loss from carrier fluids used in sand control operations.
