摘要
Abstract
This paper analyzes the mechanisms under which the hard and brittle shale formations destabilize,introduces the characteristics and application of nano materials,and summarizes the progresses made in the studies of drilling fluid nano material plugging agents,including organic and inorganic nano plugging agents.Also discussed in this paper are several case histories of the application of nano plugging agents.The authors believe that plugging agents having core-shell structures,which take advantage of the rigidity of inorganic nano materials and the deformability and filming ability of organic polymers,do not heavily affect the viscosity and gel strength of the drilling fluids in which the plugging agents can well dispersed.This kind of nano plugging agents can plug the pore throats of shales at low concentrations,thereby produce a pseudo hydrophobic "borehole wall" with some strength.This pseudo "borehole wall" not only hinders the invasion of drilling fluids,it also increases the pressure bearing of formation.The authors thus believe that the combination of inorganic nano materials and organic polymers indicates the direction for the development of anti-collapse additives in the future.关键词
