USE OF DIRECT EPOXY EMULSIONS FOR WELLBORE STABILIZATION

摘要

A direct emulsion wellbore fluid, including: a continuous non-oleaginous phase; a discontinuous oleaginous phase; a stabilizing agent; an oil-miscible epoxy- based resin; and a hardening agent; wherein the wellbore fluid is a stable emulsion having a viscosity greater than 200 cps. In some embodiments, the hardening agent is an oil-miscible hardening agent; in other embodiments, the hardening agent is an oil-immiscible hardening agent.
