In this paper, we have studied the changes in the rheological and hydromechanical properties of oil environments (oil, fuel oil, diesel fraction) at various rates of their flow and turbulence in the temperature range. A formula has been developed and the mechanism of action of a viscous-turbulent additive with a nanocomplex in the temperature range from 20 ° C to -5 ° C has been studied. The action of this composition (additive) is based on the formation of new straight-chain structures - "macromolecules" due to a...

The work is devoted to the investigation of the viscous properties of a nanostructured additive based on sevilene, as well as the evaluation of its structure by the method of IR Fourier spectroscopy on the Shimadzu IR Prestige-21 Fourier spectrometer. The structure of agglomerates of the additive is proposed, which consists of a core-nano-sized particle of aluminum oxide bound to polymers (sevilene) by associative bonds. In this case, a partial restructuring of vinyl acetate units occurs. The absorption band of 13...

In connection with finding - out of a question about probable feeding of deposits by hydrocarbons, acting from the basement, the results of integrated geologicalgeochemical research of the dynamics of variation of chemical and geochemical parameters of oils and bitumen from the rocks of sedimentary cover and basement in the zones of probable inflow of hydrocarbons at the central areas of the Romashkino oil field are presented in this work. Also the results of researches on comparative studying of changes in organi...

The work is devoted to the West Siberian sedimentary basin Bazhenov formation (or Bazhenov shale) ? a unique oil-generating and oil-bearing geological formation. Bazhenov shale is an analog of the known shale oil deposits: Bakken, Eagle Ford and Monterrey (USA). Geological and geophysical exploration of bazhenites is an important problem today, which is connected with development of new methods and technologies of unconventional oil and gas reservoirs exploitation. The work is devoted to physical and chemical prop...

The article presents the results of research on basic parameters of screw-type device designed to lift off, mix, and re-suspend sediments which build up on the bottom of the oil tank. When crude oil is stored in tanks, invariably solid particles and heavy paraffin sediments are deposited. To prevent any sediment from building up on the bottom of the storage tank and to ensure all oil requirements are met, screw-type devices or propellers which are installed at the first horizontal ring of a tank are basically used...

Many oil and gas low permeable reservoirs have been stimulated to enhance productivity. Acid fracturing is one of the commonly used well stimulation treatment in carbonate formations, such as limestone, dolomite, and chalk. Carbonate reservoirs are good candidates for acid fracturing since strong acids such as hydrochloric acid react easily with carbonate. The acid reacts within the fracture to create a differentially etched surface that will maintain a conductive pathway. Habitually, a pad fluid is injected ahead...
