The Bazhenov Formation of the Western Siberian oil-and-gas province is currently one of the key objects of potential growth in oil reserves and production. Here we present results of a geochemical study of the Bazhenov Formation according to the methodology developed at Trofimuk Institute of Petroleum Geology and Geophysics, Novosibirsk (IPGG SB RA...
This work is devoted to the development of a technique for obtaining an array of multi-walled vertically aligned carbon nanotubes (VACNT) with a thickness of up to 120 μm on Si/Al2O3/Fe substrates and to the study of their absorbing properties in the THz spectral region, as well as to the assessment of their prospects as a broadband THz radiation a...
The features of the petrographic composition of the bath-upper Jurassic silt-sand rocks exposed by wells in the South of the West Siberian oil and gas basin are considered. The study is focused on the parameters that had a significant influence on the reservoir properties of rocks: granulometric and mineral-petrographic composition of the clastic p...
We analyze the results of measurements of the thermal conductivity, porosity, and permeability of Mesozoic sedimentary rocks from wells drilled in the northeast of the West Siberian Plate and in the Cis-Yenisei basin. The thermal conductivity was measured by a “Thermal-conductivity comparator”, and the porosity and permeability were determined usin...
We use high-resolution reflection seismic data and detailed grain-size analysis of a drill core (KDP-01) from Lake Khubsugul
(northern Mongolia) to provide an improved reconstruction of the glacial history of the area for the last 450ka. Grain-size
analysis of suspended sediment load in modern rivers draining into the lake and of moraine material f...
The amplitude and phase lag of surface deformation were determined for a compliant coating under the action of turbulent pressure fluctuations. For this purpose, pressure fluctuations were measured experimentally. The amplitude and duration of coherent wave train of pressure fluctuations were investigated using digital filtration. The transient res...
The measurement method for complex compliance of viscoelastic coatings based on direct determination of deformation amplitude and pressure fluctuations was suggested. The value of dynamic deformation was about 0.02%. The frequency range was from 200Hz to 2kHz. Complex compliance of a viscoelastic coating measured was experimentally compared with ca...
It has been shown that the maximum interaction between turbulent flow and a viscoelastic coating is observed when the coating thickness is equal to one quarter of the wavelength of the longitudinal deformation of the coating surface. The amplitudes of the longitudinal and lateral deformations are equal, which must be taken into account in analyzing...
The experimentally measured complex pliability of a viscoelastic coating is compared with the theoretical calculation carried out on the basis of the measured dynamic elastic modulus and the loss factors of the coating material. The coating thickness was chosen so that the frequency ranges of determination of the viscoelastic properties and of the...
A procedure for measuring the compliance of viscoelastic coatings that are used to reduce the hydrodynamic friction has been developed (the frequency range of measurements is from 400 Hz to 2 kHz). The set of force transducers differing by the diameter of the surface of contact with a coating has been manufactured. The frequency and amplitude chara...
