FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas field, namely to methods for preparing materials applied for oil and gas well casing. The method for preparing disperse fibre-reinforced backfill containing a mineral binder, mixing water and fibrous modifying agent coiled and mixed with the mineral binder in dry form includes mixing of the dry mix of the binder and fibrous modifying agent with water; portland cement is used as a binder, each fibre of the modifying agent has a dumbbell thickening at the ends or additional fibres with length of 1/3 of the main fibre are connected to the main fibre ends at the angle of 30-90°.
EFFECT: improving adhesion degree of fibres with cement matrix thus allowing use of advantage of disperse fibre-reinforced composites.
