Mechanically degradable Polymers for Applications of working Fluids in Drilling

摘要

A composition that includes a working Fluid in Drilling and a Polymer that is mechanically labile Chemical Bonds is injected into a well and is combined with the Fluid in the wellbore to provide a Fluid Compound.It provides Mechanical Energy (e.g. Ultrasonic Energy to the Fluid in the wellbore) Compound to Cleave the mechanically labile Chemical bonds in the polymer. The Polymer can be used as a viscosifier, or Friction Reducing additive for Fluid loss. The cleavage of Chemical bonds with mechanically labile allows a precise Mechanical Energy degradation in the well.
