Research of invert-emulsion solutions properties on the basis of "Argunit RX" emulsifiers
The paper describes the "Argunit RX" emulsifier properties, which is a mixture of nonionic surfactants based on unsaturated fatty acids, and (or) its solution in petroleum products, manufactured by LLC "RudChem". The emulsifier is designed to produce reverse emulsions of aqueous solutions of nitrate salts used in the mining industry, as well as to obtain hydrophobic-emulsion hydrocarbon-based solutions used when drilling oil and gas wells. The advantages of using invert emulsion solutions for opening productive deposits at large zenith angles are described. The physical-chemical parameters of various grades of the "Argunit RX" emulsifier are given, as well as the technological parameters of an invert emulsion with the specified emulsifier at various temperatures. The results of a comparative assessment of the "Argunit RX" emulsifier quality and "Cleave FM" emulsifier produced by LLC "Mirrico" are shown, the structural-rheological properties of invert emulsion solutions using these reagents, their stability, electrical stability and other indicators are presented.
