Abstract
The article presents the results of laboratory studies of lubricating additives Flotoreagent oxal , tall oil (TM) MCHAS 30% MCHAS TM and DRC - 4mm in the compositions of bentonite slurry and natural mud Noyabrskiy oil and gas region of Western Siberia. Physico-chemical properties of the reagents and their solubility in organic and inorganic media to the foaming properties of clay dispersed systems. However, the results of experiments to assess the degree of influence on the main reagents listed (the density, rheological and structural and mechanical properties, the pH, the rate of filtration, the thickness of the mudcake) and special (stickiness mudcake) the properties of natural and synthetic muds both before and after incubation. Recommendations on the use of additives in lubricants and natural weighted drilling fluids in the oil fields of the November region. To achieve the necessary technological parameters of natural muds need concentration and oxalyl DRC - 4mm not less than 1%. They exhibit less negative side effects, in particular, foaming of a solution, stable in time have a consistency exhibit good lubricating properties. Different batches of chemical products DRC - 4mm somewhat different with different characteristics and properties. Nevertheless, the level of necessary technological properties of natural clay solution treated with the lubricating additives of the data corresponds to the wiring requirements for deep oil wells.
