Composite high-filled polymer reagents for drilling fluids that improve the performance of rock-breaking tools in the process of drilling oil and gas wells

The paper presents the results of studies of the important physicochemical and technological parameters of the CCR-2 composite highly filled polymer chemical reagent, consisting of Na-CMC, alumac, soda ash and caustic soda and waste from the production of chemical fertilizers, as well as drilling fluids based on it. The compositions and physicochemical properties of the waste-slag of the chemical plant of Farg'onaazot JSC, which increases the density and water index of drilling fluids, were studied in detail. The optimal compositions of composite polymer chemical reagents of CCR-2 class using waste-slag from chemical production of fertilizers have been developed. The physicochemical and technological characteristics of the developed composite highly filled polymer chemical reagents KHR-2 (from KHR-2-1 to KHR-2-5) and 10% low and medium density drilling fluids based on them are given.
