The author paid attention to studying the properties of various supplies “Uniflok” reagent batches. Checked his influence on the properties of natural and artificial wells with mud. Reagent was injected into the drilling fluid, both in dry form or after dissolving in water. We studied the compatibility of the polymer “Uniflok” with others, used in the November oil and gas region of Western Siberia, the reactants. It is found that the properties of inhibiting the hydration of clays has no reagent. At the same time, “Uniflok” additive in water lead to positive decrease surface tension at the liquid paraffin. Reagent “Uniflok” is compatible with the reagents SNPCH 6012 and “Emultal” and “Ak-Drill”. In the former case, this leads to an increase in hydrophobic properties and improved lubricity of the system and in the second case to reduce the filtration rate to required values. Because by itself “Uniflok” along with an increase in the structural and rheological parameters of the solution does not provide the necessary filtering of decline in the mud.
Samples “Uniflok” agent of the Tomsk higher quality, but they also do not meet all the requirements. It is also desirable to introduce muds in dry form. Although a reduction in filtration rate, but this is still not enough for low reagent concentrations, and at higher – beyond the boundaries of acceptable values of the rheological parameters. However, the active agent with these characteristics may well find application in thickening drilling fluid used to drill a conductor hole, a high viscosity solution when required.
In view of the currently existing problems of import agent “Uniflok” may well be used in drilling muds in combination with other filtration reducers and thinners muds.
