The based on natural raw materials and waste compositions of raw mixtures allowing to receive a oil-well portland cements are developed. Oilwell technical properties of cements correspond to the requirements of state standards by consistency, thickening time, water separation, strength and other parameters. Replacement of quartz sand on electrothermophosphoric slag allows to improve clinker burning process and to reduce specific fuel consumption.
