ASPHALTENIC-RESINOUS COMPONENTS AND NITROUS COMPOUNDS OF RESIDUAL OILS

Abstract

There the study was executed with the samples of extracting and residual oils from number of deposits of West Siberia and Ural-Volga Region. The samples of extracting oils have been made from the producing pools of deposits to be exploited by the flooding method. The residual oils have been extracted according to the offered procedure by the alcohol-chloroform mixture from the tight packed cores from the well-irrigated zones of corresponding pools. The purpose is to study the nature and the surface-active properties of high-molecular components and nitrous compounds of residual oils from the flooded pools which were formed by the sand deposite of different age. The data about the composition and about the surface-active properties of residual oils have been obtained for the first time, the distinctions of structural-group composition of asphaltenic-resinous components and nitrous compounds have been brought out. They exhibit the influence of oxidizing and sorption processes which take place in the flooding terrigenous collectors on the composition of native oils. The new scientific results about the surface-active properties of residual oils and their components have been obtained. The deductions which are concerned with the surface activity of concentrates of nitrous bases in the oil - aqueous phase interface are of interestAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
