Study abroad lubricant additives muds Duna-Drill DL-365 and ClearLube-6156

摘要

The article presents the results of laboratory studies of foreign lubricating additives Duna-Drill DL-365-6156 and SlearLube in the compositions of bentonite slurry and natural mud Noyabrskiy oil and gas region of Western Siberia. The physicochemical properties of environmentally foreign reagents, their solubility in organic and inorganic media, foaming properties in the clay dispersion systems. Furthermore, the obtained data of numerous experiments on the influence of foreign judge reagents and special core (in particular, the stickiness of the mudcake), artificial and natural properties of drilling fluids. Recommendations on the use of lubricating additives in the oil fields of the region with its characteristic processing of various chemicals alluvial muds. To achieve the necessary technological parameters of drilling fluids lubricating additive Duna-Drill DL-365 should be used with defoamer (eg Pentor-2001) in an amount of more than 1.5%, and lubricant additives SlearLube-6156 can be used without defoamer in an amount of more than 1%. Industrial model DL-365 led to more effective foaming muds and prototype had faint blowing effect. Stickiness mudcake decreased by adding a sufficient level of mud in the industrial model DL-365 with multiple higher concentration than with the prototype. Introduction Industrial sample DL-365 resulted in a bentonite slurry to increase the structural and mechanical properties, and processing of the experimental sample solution - decreasing. Consequently, the chemical composition of samples submitted reagents with various parties differed significantly from each other. This situation is typical for the supply of domestic chemicals.
