DELAYED DELIVERY OF CHEMICALS IN A WELLBORE

摘要

Methods and systems of delivering a treatment chemical are disclosed, including providing a plurality of porous particles each having an outer surface, wherein each of the plurality of porous particles comprises a plurality of pores; infusing the plurality of porous particles with the treatment chemical; coating the plurality of porous particles with a degradable film; adding the plurality of porous particles to a carrier fluid, wherein the degradable film substantially separates the treatment chemical from the carrier fluid; introducing the carrier fluid into a formation; and allowing the degradable film to degrade within the formation
