DOMESTIC AND FOREIGN STUDIES LUBRICANTS ADDITIVES DRILLING MUD

摘要

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.
