IMPROVING THE IMPACT OF CEREAL CLAME IN OIL HOLDERS ACCORDING TO GEOLOGICAL INFORMATION CONTAINING POULTRY OR POULTRY STOCKS

摘要

Methods of treating wells for cementing operations and for improving placement of cement in wells containing water swelling clays include treatment of the well with a fluid containing clay precipitating agents capable of coagulating clays in the well. The coagulating fluid can contain quaternary ammonium salts, aqueous salts of potassium or cesium, or silicates as the clay coagulating agent. The coagulating fluids can be applied to convert soft mud cake into hard mud cake prior to placement of cement.
