Specifying the Methods to Calculate Thermal Efficiency of a Dual Production Well System "Fluid-Geoheat"
(2022) Fyk, M. I.; Biletskyi, V. S.; Abbood, M.; Desna, N. A.
Methods to calculate thermal efficiency of dual production well system “fluid-geoheat” have been specified for conditionally thin productive fluid-saturated seam in terms of radial planar filtration. It has been demonstrated that relative to a variant, ignoring Joule-Thompson effect, and variant of discrete Joule–Thomson coefficient substitution, calculation accuracy as for the well heat efficiency increases by 33% and 9% respectively. It has been proved that it is expedient for a conditionally thin seam to use effective temperature within the heat-exchange equitation with Fourier substitution as related to heat transfer while considering heat input in terms of unidirectional input to a virtual disk plate from the seam floor. In the context of the proposed calculation methods, increase in numerical estimations of thermal efficiency of a well results from the consideration of extra heat pumping owing to Joule-Thompson effect by rocks adjoining the productive formation.
Phenomenological model of an open-type geothermal system on the basis of oil-and-gas well
(2020) Fyk, M. I.; Biletskyi, V. S.
This paper relates to mining-well technologies. A theoretical and methodological approach is proposed to modeling geothermal well systems, which includes the development of: principal technological scheme of a geothermal system; schemes of transformation and movement of energy and a heat-transfer medium; the geothermal system phenomenological model; analysis of subprocesses and obtaining their mathematical models and, on this basis, the mathematical model of the geothermal model as a whole. An example of an advanced open-type geothermal well system is studied, which is based on the oil-and-gas well with one loop of circulation and the parallel connection of heat pumps at characteristic points of the system. The subprocesses of the developed phenomenological model are analysed and the characteristic features of their mathematical description are revealed; in particular, it is substantiated that the redistribution of heat power entering from a fluidsaturated bed is substantially dependent on the lateral wellbore geometry. Another important feature is to model the downhole heat pump and the modes in the scheme as a whole, which is based on the mass flow rate of a heat-transfer medium in its circulation loop. A generalized formula is presented for the heat power of the analysed advanced geothermal well system.

(2018) Fyk, M. I.; Biletskyi, V. S.; Abbud, M.
The objective of the work is to substantiate the actualization of the problem of obtaining geothermal energy from oil and gas wells of oil and gas production facilities in the central-eastern part of the Dnieper-Donetsk Depression (DDD). The research methodology is based on the collection and statistical processing geophysical data of the DDD oil and gas deposits, the use of balance equations for energy and substance matter. The main result of the work is that the principal technological scheme of the geothermal system has been developed and the geothermal potential of oil and gas wells in the experimental zone has been analyzed. There have been considered the technological and ecological aspects of geothermal heat usage from depleted deposits of the DDD wells, which were disclosed into сarboniferous deposits productive horizons.
Improved thermogasodynamic model of a geothermal gas condensative deposit with production well
(2019) Fyk, M. I.; Biletskyi, V. S.; Al-sultan, M. B.; Abbood, M. H.
It is shown in the work that the wells-fluid are extracted from rocks by heat-retaining fluid from the open geothermal reservoir as from object with distributed cross-sectional parameters. This is due to the fact that the actual temperature distribution of the geothermal reservoir in dynamics affects the thermal properties of fluid-retaining rocks, which in turn affect the coefficient of heat exchange and heat transfer along the cross-section between the moving fluid, the fluid-retaining layer and adjacent rocks. The static temperature field of the original geothermal gradients in the case of outflow injection of the circulating coolant changes from the sides of the reservoir to the wellbore. A model of geothermal reservoir of gas-condensate well has been developed, which takes into account changes of thermal conductivity of rocks from the reservoir counture to the well bottom. The model includes refined equations of thermal energy balance for radial filtration of well production, containing convective and conductive components of heat exchange and heat flow. This allows, in comparison with the known methodological approaches, to clarify by 12-14% the forecast of heat extraction from a geothermal reservoir with a circulating coolant thrue the bottom and productive layer of a gas-condensate well.
Analysis of Dynamical Heat Conductivity of the Reservoir and Fluid Evacuation Zone on the Gas Condensate Well Flow Rate
(2020) Anzian, Kouadio Fabrice; Fyk, M. I.; Mohammed, Bassam Al-Sultan; Abbood, Mohammed Khaleel; Abdullatif, Haval Mohammed; Shapchenko, Ye. A.
This study shows that the thermal conductivity of the rock borehole adjacent to the wells varies depending on the operation of the well. This is due to the fact that the actual temperature and temperature difference affect the humidity and other thermal properties of the rocks, which in turn affect the heat transfer coeffcient across the section between the moving gas and the rocks. The static temperature field of primitive geothermal gradients acquires changes in a dynamic form. Theoretical consideration of changes in the thermal conductivity of rocks near the face and the wells is proposed to improve the prediction of gas condensate wells production. The result is achieved by introducing the specified equations of the thermal energy balance in the radial filtration and lifting of well products, which contain the coeffcients of heat exchange and throttling. The refinement bias estimation of the 10%–15% level of gas condensate well extraction is shown using proposed methodological approach to relatively well-known (traditional in the field development practice) methods for estimating the extraction of a “medium well” from a particular oil and gas field evaluation. The results of this work demonstrate important scientific, applied, educational and methodological significance of using the methodology presented by the authors.
Analysis of the technology to manufacture a hightemperature microstrip superconductive device for the electromagnetic protection of receivers
(Технологічний Центр, 2018) Fyk, Oleksandr; Kucher, Dmytro; Kucher, Larisa; Gonchar, Roman; Antonets, Volodymyr; Fyk, M. I.; Besedin, Yuri
Technological features of the process of manufacturing a high-speed high-temperature superconducting microstrip protective device which can reduce in a picosecond period (the time of switching or operation speed) the incoming power from the antenna-feeder path and the power passing through it to a level safe for sensitive semiconductor elements of the receiver (preventing current destruction of p-n junction). The study enables determination of the features and conditions for the use of modern technological methods for creating a superconducting microstrip protective device taking into account influence of the substrate material, superconductor and contacts and the method of their connection on the switching properties of superconducting films of the proposed protective device. The switching properties of superconducting films include speed of phase transition of a film from a superconducting to a nonconducting state. To determine degree of material influence on switching properties, it was proposed to use the following: lattice parameter, thermal expansion coefficient of materials, degree of interaction of molecular structures of the contacting surfaces, probability of local defects on the surface (nonconducting zones). The study outlines basic conditions (methods of film deposition, applying a certain superconducting film (YBCO) on the chosen substrate) which should be met in order to create an operable protective device. The study results make it possible to assess the degree of influence of contact materials and the method of deposition (of both film on the substrate and contacts on the film) on microstructure and switching properties of the superconducting protective device. Such results can be used in synthesis of high-temperature superconducting devices for protecting receiver elements from current destruction of their p–n junctions.
Examining the current of drilling mud in a power section of the screw down-hole motor
(Технологический центр, 2018) Biletskyi, V. S.; Vitryk, V.; Mishchuk, Y.; Fyk, M. I.; Dzhus, A.; Kovalchuk, Yu.; Romanyshyn, T.; Yurych, A.
By using the module Flow Simulation from the programming environment SolidWorks, we obtained parametric fields of turbulent flow of drilling mud in the subject of research – a power section of the screw down-hole motor (SDM). The subject of research is the characteristics of turbulence of the drilling mud flow. An analysis of the obtained model parametric fields of turbulent flow of drilling mud in the power section of SDM shows two distinctive regions that differ by the characteristics of turbulence in the drilling mud current. These sections are localized in the neighborhood of contact points "rotor-stator", and along the distance between these points. In the first section, the developed flow turbulence almost disappears; the dissipation of flow energy significantly decreases. In the second section, there is a developed turbulence of drilling mud, which causes increased dissipation of flow energy and a possible damage to the stator by a solid phase of drilling mud. Turbulent time scale in the second region reaches the minimum values of 0.001 s, and the metrical scale of pulsations is comparatively small – from 0.011 to 5.666 m, indicating the presence of small-scale turbulent vortices and the elevated dissipation of flow energy. Thus, the second section is the most vulnerable to a damage to the stator by a solid phase of drilling mud. An endoscopic examination of the surface of the SDM stator, which we conducted, revealed damage to its working surface, specifically deep scratches, guide scratches, cavities. Localization of damage is from the middle and to the tail part of the power section at a distance of 2.53−4.78 m from the beginning of the power section of SDM. The models obtained are recommended for using in hydraulic calculations of SDM, for choosing a rational mode of its operation.
