METHOD FOR PRODUCTION OF CARBONATE WEIGHTING MATERIAL FOR DRILLING MUDS

摘要

FIELD: well drilling; production of weighting material for drilling muds. SUBSTANCE: method includes crushing of carbonate raw material in crusher of selecting crushing with screen, drying and grinding of final product. During crushing, in crusher of selecting crushing with screen, silicon is removed from carbonate raw material. Silicon may also be removed after crushing of carbonate raw material in drum separator. Clay and sand are removed from carbonate raw material before grinding of final product in gravity separator. EFFECT: higher efficiency. 1 dwg, 2 tbl.
