Abstract: To improve the environmental safety of tires the use of plasticizers derived from extracts of selective treatment by propane de-asphalting in commercial tire stocks for passenger cars was studied. Comparative tests with commercial samples of environmentally friendly oils were carried out. It is shown that plasticizers obtained by propane de-asphalting are flexible in processing rubber and possess better physical and mechanical properties in comparison with control samples. Thus, the presented plasticizer is a promising alternative to aromatic oils. This product allows reducing the impact on the environment and contributes to the expansion of the product line of domestic agents

Abstract: There are no qualified applications of the extracts oil distillate selective treatment, wherein the extracts contain surface active agents, which show antiwear, antioxidant and adhesive properties. The possibility of using solvent refining extracts oil distillate selective treatment as a component of lubricants dispersion medium was investigated. Rheological, low-temperature, oxidation and surface properties of solvent-refined extracts oil distillate selective treatment and its mixtures of mineral base oils were determined. It was established that at concentration 40 % by weight of the extract in a mixture of industrial oil tensile strength, oil separation characteristic, oxidation stability, low temperature properties, adhesion to metal surfaces and lubricity are increased. Greases based on the extracts have a lower cost in comparison with conventional lubricants based on oil mixtures

Abstract: This paper investigates the effect of viscosity modifiers on the low-temperature properties of alkylbenzene oils as well as the resistance of additives to mechanical destruction. It is shown that copolymers of ethylene and propylene as well as polyisobutylene are also effective viscosity modifiers for alkylbenzene oils, however they show inadequate resistance to mechanical degradation as compared with foreign counterparts

Abstract: Development of new transducers of water content of oil with higher measurement accuracy and sensitivity is an important task, since the use of existing electric moisture meters of both commodity and crude oil is significantly limited in operating conditions. A considerable additional error up to 1-5 %, occurs when the resistance of the formation water in the emulsion bypasses the capacity of the measuring sensor. The article discusses the digital pulse electric transducer of water content with automatic error correction, taking into account the influence of the conductivity of water-oil emulsion

Еxpansion of resource BASE of diamond-like structure hydrocarbons
Chemical sciences

Authors: Maxim V. GIRUTS graduated from Gubkin Russian State University of Oil and Gas in 2004. PhD (Chemical Sciences), assistant professor of the Department of organic chemistry & petroleum chemistry, Gubkin Russian State University of Oil and Gas. Specialist in chemistry and geochemistry of petroleum hydrocarbons. Author of more than 60 scientific publications. E-mail: moxixh@yahoo.com

Abstract: Diamond-like structure hydrocarbons due to their physical and chemical properties features find a wide range of applications in various fields of science, technology and industry: nanotechnology, medicine, manufacturing of highly resistant polymer materials and others. However, the existing methods for the synthesis of diamondoids are complex and multistage, and require further improvement. We performed thermolysis of asphaltenes, resins and high-molecular saturated (boiling above 350 °C) petroleum fractions of different genotypes, catalytic transformations of paraffin-cycloparaffinic fractions (boiling within 180-350 °C above 350 °C) of oils, catalytic thermal transformations of oxygen-containing compounds - precursors of petroleum hydrocarbons, thermo-lysis of macromolecular n-alkanes, as well as catalytic transformations of biomass of bacteria. Analysis of the hydrocarbon composition of the original oils, paraffin-cycloparaffinic fractions, thermolysis products and catalytic transformations was carried out by capillary gas-liquid chromatography and chromato-graphy-mass spectrometry. We have found that diamond-like structure hydro-carbons C10 to C23 form as a result of the above transformations. Thus a possibility of obtaining hydrocarbon of adamantane series from alternative sources was shown

The influence of porosity and permeability of carbonate reservoirs on oil recovery factor
Drilling and development of hydrocarbon fields

Authors: Larisa N. NAZAROVA graduated from Gubkin Moscow Institute of Petrochemical and Gas Industry in 1979. She is Candidate of Technical Sciences, Associate Professor of the Department of Development and Exploitation of Oil fields of Gubkin Russian State University of Oil and Gas.

Abstract: One of the main technological parameters of efficiency of development of oil fields has been oil recovery factor (ORF). Its value is influenced by a number of natural factors. 197 layers were analyzed to assess the impact of reservoir porosity and permeability of a carbonate porous type reservoir on the magnitude of the calculated and actual final ORF. It is shown that the calculated and actual values of the ORF do not always correspond to a certain set of reservoir properties. The degree of divergence of the calculated and actual values of the ORF depends on the reservoir porosity and permeability of the productive strata
