Experimental Application of Salt Slurry in Talimu High Density Drilling Fluid Composed of KCl-Saturated Brine and Polybasic Alcohol

Abstract:

Salt slurry is the semi-solid waste of the salt industry. The study object was the salt slurry before filter in Jianghan Salt & Chemical Complex. In laboratory, this study investigated the application of the salt slurry in Talimu high density drilling fluid which composed of KCl-saturated brine and polybasic alcohol. It indicates that on the premise of the same density and pH value as the basic drilling fluid recipe, when the salt slurry dosage is less than 500 kg/m³, all the salt slurry application-based recipes measure up both the rheology behavior and the filtrate loss of the drilling fluid. This investigate will reduce the cost of the drilling fluid with the salt slurry as a resource.
