COMPOSITIONS CONTAINING FURNACE DUST AND WOLLASTONITE AND METHODS FOR USING THEREOF IN UNDERGROUND FORMATIONS Russian patent published in 2018 - IPC E21B33/13 C04B18/08 C09K8/467 C04B18/04 C04B28/02 C04B111/20 

Abstract RU 2640621 C2

FIELD: mining.

SUBSTANCE: method for cementing includes: providing a hardening composition containing furnace dust, wollastonite, and water. The content of wollastonite in the hardening composition forms about 1% to about 75% by weight relative to total number of cementing components contained in the hardening composition, in this case, the content of furnace dust in the hardening composition is from 5% to about 90% by weight relative to the total number of cementing components, in the hardening composition, providing possibilities for setting of the composition. The hardening composition is intended for introduction into the underground formation. The invention is defined in the dependent claims.

EFFECT: decreased cost of slurry for cementing.
