FIELD: oil and gas production.
SUBSTANCE: invention refers to oil and gas field, namely to methods for preparing materials applied for oil and gas well casing. A method for preparing a fibre-reinforced backfill containing a mineral cementing agent, tempering water and a fibre builder dry-mixed with the mineral cementing agent, and each fibre of the builder is coiled, and it is uncoiled when mixing the backfill with the tempering fluid.
EFFECT: maintained compositional uniformity of the prepared backfill, and prevented locking of a preparation unit aperture with the fibre builder in cementing units.
