FIELD: methods or devices for cementing, for plugging holes, crevices, or the like, particularly for well killing. ^ SUBSTANCE: method involves determining vertical and side rock pressure in formations along well depth; determining formation pore channel dimensions and dimensions of solid natural material particles, which may be introduced in the pore channels, and number of particles; reconstituting conditions identical to that in undrilled surrounding rock at formation location levels by filling well bore with mixtures including plastic natural materials and solid natural material particles instead of cement, wherein the materials are inert to formation product and rock. The mixtures have volumetric densities, which provide well bore pressure equal to that of formation outside well. ^ EFFECT: increased well killing efficiency. ^ 4 cl |
