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.
The effect of lubricant additives DRC-KTM-TMI DRC, DRC-TM-10, DRC-4mm, and Glitall DIPENTEN the basic and special properties of bentonite suspensions and natural polimerglinistyh drilling muds November oil and gas regions of Western Siberia. The information on the physico-chemical properties of the reactants. The results of testing the solubility of the reagents in different environments. The experience to identify the level of foaming clay dispersed systems, depending on the concentration of lubricant additives. In the same range of concentrations of reagents was studied in detail the stickiness of clay crust, created from natural and artificial solutions. Preliminary conclusions and recommendations.
All of the above reagents have lubricating properties, but not all reagents are suitable for use without any defoamers. Technologically acceptable concentrations of reactants are in the range of 1-3% (vol.). Reagents DRC-KTM DIPENTEN and do not affect the rate of filtration of bentonite suspensions and reagents DRC-TMI, DRC-TM-10, DRC-4mm, Glitall lead to a decrease in filtering by about a quarter. However, the influence of the same reagents on the filtration rate of natural muds immaterial. The final decision on the possibility of using the reagents provided in the Noyabrsk region should be taken after the industrial tests, but at this stage of the research the most suitable properties are inherent lubricant additives DRC-PM10. For other reagents necessary to choose an effective anti-foaming agents. Otherwise the success of field tests is questionable. In addition, the lubricant additive Glitall does not have sufficient frost resistance for use in the Far North.
