Description
Summary:A study was carried out on the feasibility of obtaining a modified lignosulfonate reagent by dispersing an additive synthesized using acrylamide, formalin, and malic acid. We determined the optimal component ratios for the preparation of this modifier and the modified lignosulfonate reagent through mathematical modelling using the Statistica 12 program package. The composition of the additive to the lignosulfonate drilling reagent was studied by high-performance liquid chromatography. Analysis of the two-dimensional correlation of the homo- and heteronuclear spectra, integral intensities in the 1H NMR spectra and the mass spectra of an experimental sample of the synthesized additive indicated the structure of this compound. Comparative analysis of the surface tension of the samples studied was carried out by the stalagmometric droplet counting method. The effectiveness of the synthesized additive and the modified lignosulfonate reagent for improving the parameters of the drilling mud at high temperature up to 180°C was demonstrated experimentally.
