Technical requirements for measurements of minimal miscible pressure for gas injection using slim tube
Β© 2020 International Multidisciplinary Scientific Geoconference. All rights reserved. In this work the quality of the slim-tube packing was demonstrated, the inner diameter and porosity was determined by using X-ray computed tomography. The literature analysis of slim tube packing over was carried out. It is noted that in all cases of slim tube does not accept the most theoretically possible dense rhombic packaging. Moreover, the presence of interstices due to loose contact of the grains to each other illustrates the technological limitations when filling out. To confirm the absence of signs of defective packing, it is recommended to check the quality of the slim-tube
Improvement of heavy oil displacement efficiency by using aromatic hydrocarbon solvent
Β© 2020 International Multidisciplinary Scientific Geoconference. All rights reserved. Development of heavy oil deposits increases each year, due to consumption of conventional oil reserves. However, extraction process of heavy oil faces a number of problems. The main of these problems are high density and viscosity of heavy oil as well as high content of asphaltene-resin-paraffin components, which can be precipitated. Currently, the main methods that are being used for heavy oil recovery are thermal methods, like steam assisted gravity drainage (SAGD), cyclic steam stimulation (CSS) and in-situ combustion (ISC). Another alternative is using solvent-based recovery methods, which have advantages in terms of energy effectiveness and cost efficiency. In this work, using aromatic hydrocarbon solvent is considered as an oil displacement method. Solvent o-xylene has been chosen as the research object due to its vast area of application and ability to remove organic deposits. In this work different experimental techniques were conducted to evaluate the injection of xylene for improvement heavy oil recovery. Capillary imbibition experiments of oil saturated core samples by formation water and xylene solvent were conducted in order to compare their effectiveness under standard conditions. Filtration studies under reservoir conditions were performed on a core sample model saturated with heavy oil to evaluate displacement efficiency. In addition, filtration-volumetric parameters of core samples, group and elemental composition of oil, viscosity dependence on a solvent concentration, thermal stability of solvent as well as its aggregative stability were studied. According to the obtained results, application of o-xylene in imbibition experiments (duration 7 days) helped to increase displacement efficiency from 20 % in case of water to 61 % in case of solvent. Addition of small amount of solvent to heavy oil significantly decreased its viscosity. In case of addition of 3 wt.% of solvent viscosity of heavy oil reduced more than two times from 427.18 mPaΒ·s to 208.4 mPaΒ·s. Compared with the basic waterflooding process, using solvent injection leads to three times increasing of oil displacement efficiency, which reaches 69 %. In addition, o-xylene showed good dissolving ability with lowest cloud number of heavy oil in its media, which is equal to 0.22. According to the laboratory studies pilot test will be performed at the Akanskoye field using studied solvent

products will allow for the adaptive management of the assembly based on the measured
information. Direct simulation of the conjugation process using numerical models of interfaces
and finite element models of assemblies requires significant computational resources and is
often accompanied by convergence problems of solutions. To solve these problems, it is
possible to use neural network models describing the main regularities of the conjugation
process on the basis of accumulated results. In this paper, a technique is given for predicting
the accuracy of the interface of parts on the basis of real geometric models of surfaces. The
actual parts models are arrays of points on their surfaces. The methodology uses the developed
model, which allows to calculate the assembly geometric parameters of parts. The results of
modeling the mating of disk and spacer of the turbine rotor are considered. To predict the
parameters of radial runout of the disk in the assembly, depending on the magnitude and nature
of the form deviation and the magnitude of the gap of the interfaced surfaces, a radial-basic
neural network was created and trained.Π Π°Π±ΠΎΡΠ° ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠ°Π½Π° ΠΠΈΠ½ΠΈΡΡΠ΅ΡΡΡΠ²ΠΎΠΌ ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ ΠΈ Π½Π°ΡΠΊΠΈ Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ Π² ΡΠ°ΠΌΠΊΠ°Ρ

In CAM-systems (Computer-aided manufacturing), it is possible to simulate the measurement process on the machine and coordinate measuring machine, and generate measurement commands in the control program. Measurements can serve as the basis for the implementation of various adaptive processing schemes. The main advantage is that, based on the measurement results, you can automatically adjust the machining process without removing the parts from the machine. When measuring complex parts on the machine and coordinate measuring machine (stamps, engine blades), measurement uncertainties significantly increase, which are not calculated in modern CAM-systems (for example, NX from SIEMENS and CATIA from DassaultSystΓ¨mes). This can lead to a loss of processing precision (due to inadequate measurement accuracy) with an externally debugged program. The paper proposes a model and a software module for the prediction of measurement uncertainties, implemented by means of the NX OPEN API, which can be integrated into the CAM module.Π Π°Π±ΠΎΡΠ° Π²ΡΠΏΠΎΠ»Π½Π΅Π½Π° ΠΏΡΠΈ ΡΠΈΠ½Π°Π½ΡΠΎΠ²ΠΎΠΉ ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠΊΠ΅ ΠΠΈΠ½ΠΈΡΡΠ΅ΡΡΡΠ²Π° ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ ΠΈ Π½Π°ΡΠΊΠΈ Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ Π² ΡΠ°ΠΌΠΊΠ°Ρ

To predict the quality parameters of products (in particular, the assembly parameters) used mathematical models implemented in the form of computer models. For the adequacy of calculations, it is necessary to have information about the actual geometry of the parts, which can be obtained using noncontact measurements of parts of the assembly. As a result of measurement of parts and components using optical or laser scanner is formed an array of measured points large dimension. After the standard processing (e.g. noise removal, combining the scans, smoothing, creating triangulation mesh) becomes necessary recognition of individual surfaces of parts. The paper presents a neural network model that allows the recognition of elements based on the use of an array of measured points obtained by scanning.Π Π°Π±ΠΎΡΠ° ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠ°Π½Π° ΠΠΈΠ½ΠΈΡΡΠ΅ΡΡΡΠ²ΠΎΠΌ ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ ΠΈ Π½Π°ΡΠΊΠΈ Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ Π² ΡΠ°ΠΌΠΊΠ°Ρ

The quality of aircraft and rocket engines depends primarily on the geometrical accuracy of assembly units and parts. To predict the quality parameters (in particular, the assembly parameters) used mathematical models implemented in the form of computer models. Direct modeling of the process of assembly using numerical models of conjugations and finite- element models of assemblies requires significant computational resources and is often accompanied by problems of convergence of solutions. To solve the above problems, it is possible to use neural network models describing the main regularities of the pairing process based on the accumulated results. The paper shows a neural network model for predicting the parameters of assembly parts based on the use of real surfaces of parts obtained as a result of mathematical modeling. Considered assembly on conical surfaces. To predict the parameters of the assemblies, a convolutional neural network was used.Π Π°Π±ΠΎΡΠ° Π²ΡΠΏΠΎΠ»Π½Π΅Π½Π° ΠΏΡΠΈ ΡΠΈΠ½Π°Π½ΡΠΎΠ²ΠΎΠΉ ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠΊΠ΅ ΠΠΈΠ½ΠΈΡΡΠ΅ΡΡΡΠ²Π° ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ ΠΈ Π½Π°ΡΠΊΠΈ Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ Π² ΡΠ°ΠΌΠΊΠ°Ρ
