The invention discloses high-water-loss plugging agent
solid-phase plugging particles for a
drilling fluid. The high-water-loss plugging agent
solid-phase plugging particles are prepared from the following raw materials in parts by weight: 50-60 parts of
bisphenol A
epoxy resin, 10-20 parts of an auxiliary agent, 50-60 parts of a
fiber material and 16-20 parts of a curing agent; a
fiber material is added in the preparation process, so that the strength, the
hardness, the fullness and the stability of the
solid-phase plugging particles are enhanced; the
fiber material is small in size and can be used for filling gaps in the solid-phase plugging particles, so that the solid-phase plugging particles become more compact and are not easy to deform due to change of external conditions. An auxiliary agent is also added in the preparation process; azo diamide and
sodium bicarbonate in the auxiliary agent have a foaming effect, so that a microporous structure is formed in the generated solid-phase plugging particles, the
drilling fluid can quickly lose water on the plug surface, the influence caused by overlarge pressure due to quick water loss is reduced, and meanwhile, small-particle-sizeparticles can be effectively blocked.
