On dynamics of changes of the engine Raba-Man D 2156 HM6U lubricant oil characteristics

In the paper the results of research of operational oils Mobil 15W/40 and Powerway 15W/40 used in the bus engine Raba-Man D 2156 HM6U received by a complex method of infra-red spectroscopy and ferrography have been considered. On the basis of these results optimum terms of change of lubricant oils Mobil and Powerway recommended for engines of the given type have been established, and dynamics of oil ageing has been established.

Use of surface-active reagents for stimulation of oil production at the original and secondary opening of layers

A complex study of surface-active substance SCA-515 containing Neonol AF 9-12 – oxyethylated monoalkylphenol as a nonionic surfactant has been performed. It is shown that the SCA-515 does not interact with the deposit water, shows demulsifying properties, reduces the interfacial tension to ultralow values, adsorbs slightly on the core. The effects of ionic strength and nature of electrolyte on the surface properties of surfactant have been studied. The composition of the punching liquid for secondary access technologies based on the surface-active substance SCA-515 and an aqueous solution of potassium chloride has been found. Researches of the designed punching fluid have shown its high inhibitory ability, compatibility with formation fluid and mud filtrate. Industrial (Peschanoozerskoe field) tests have shown high efficiency of surfactants: flow rates increasing, the term reduction of well development and decrease of skin effect.

Use of fish oil as surface-active properties in technological processes

The lubricant additive on the basis of fish oil for improvement of tribotechnical and surface-active properties of a chisel solution has been offered. Surface-active properties of the new lubricant additive have been investigated. Lower consumption of the proposed component as compared to the traditional lubricant additive has been marked. Ecological safety of the lubricant additive on the basis of fish oil has been shown.
