  • Features of the development of offshore oil fields

    "This article discusses the process of salt formation in the development of oil fields. The relationship of the hydrogeological environment with oil deposits, as well as the influence of hydrogeological conditions on them. The influence of the hydrogeological properties of oil fields, which affect the formation of salts directly during the development of an oil field, is considered. The article presents the problems of the formation of salt deposits, the main salts that are most often found by industrial oil workers in the development of oil fields.Oil companies are constantly spending tremendous amounts of money on salt deposits. Modern industrial oil companies use mechanical, chemical methods of salt control and use inhibitors to prevent their formation. Using these methods is effective, but quite costly. In order to prevent the occurrence of salts, a cheaper method is modeling. And also such a method can prepare specialists in advance for a future problem with deposits. From what it can become clear which funds should be involved in the fight against these deposits"

  • Algorithm to control saturation contrast of digital images and its program realization

    The paper deals with virtual-optic image processing, particularly – with contrast enhancement, specifically – with control of color saturation contrasts in order to detect latent graphic information. The theorem of a hue invariance at color saturation through RGB-coordinates shift and its brightness restoration through RGB-coordinates proportional variation is proved. Meeting the corresponding requirements for analytical software tools, the original algorithm and program to enhance saturation contrasts were developed. The truncated brightness equation is presented. The possibility to optimize the speed versus accuracy of the conversion is laid. The program was successfully approved: a significant increase in the information content of the image was recorded. The efficiency of the created software product application to expert problems is demonstrated.

  • Physico-chemical aspects of the formation of multicomponent solid solutions in an inhomogeneous thermal field

    The theoretical aspects of crystallization of multicomponent solid solutions are discussed. Antimonoid heterosystems in which bismuth is present are considered, a component that largely determines the photoelectric properties of the studied materials. The features of establishing the equilibrium of the liquid and solid phases in the process of crystallization of these systems are considered. The laws of the thermodynamic behavior of heterosystems in the conditions of gradient liquid-phase epitaxy are established.

  • Determination of internal stresses inside a bimetallic rod

    The study of the internal friction of electrolytic coatings is complicated by the impossibility of obtaining sufficiently massive samples and testing them independently of the substrate, and therefore it is necessary to evaluate the stress state of the sample-coating system. The aim of the work was to find a relationship between the internal stresses arising in the coating deposited on a circular cross-section specimen during internal friction tests using a torsion pendulum. During the analysis of the stress-strain state of the bimallic sample, expressions were found to calculate the maximum and minimum stresses in the electrolytic coating. The mutual influence of the coating material and the substrate was evaluated numerically using the Comsol Multiphysics program.

  • Solving the planning routes problem with time constraints

    Many organizations in the process turn to services related to the delivery of different categories of cargo. Transport logistics is responsible for the process of moving the required amount of cargo to a given point using the optimal route. At the same time, there is often an additional restriction - the delivery of cargo to a given point should be carried out strictly during a certain time interval. The presence of time restrictions lead to the fact that the routes formed without their consideration are not permissible. This article considers developing a solution of the planning and optimizing routes problem with time constraints.

  • Assessment of the suitability of water resources of water wells for water supply of rice systems in floodplain areas

    This article discusses the possibility of using water wells for water supply of rice irrigation systems. The aim of the study of this work is to study the prospects for the possible use of water wells for irrigation of flood fields of the Krasnodar Territory. This issue has been studied by the example of a water well, which is located in the village of the Black Sea Seversky district of the Krasnodar Territory. The relevance of the study of this issue is expressed in the fact that of all types of agricultural nature management in the Krasnodar Territory, one of the most important types is rice growing. Naturally, in the field of rice production, irrigation sources play an important role, which, in our opinion, include water wells. The relevance of this study is associated with the importance of the production of rice groats, as one of the most important types of agricultural nature management in the Krasnodar Territory and the Republic of Adygea. Irrigation sources are of great importance in the field of rice growing, which consists in the fact that for the irrigation of flood fields, a large amount of water is required, providing a favorable environment for rice growth. At the same time, the quality of rice cultivated directly depends on the qualitative characteristics of the water resources used for rice systems. The value of irrigation sources is that a favorable environment for the cultivation of rice groats is created by water resources, which are used in large quantities for irrigation of rice fields. Water resources used for irrigation of flood fields have a direct impact on the quality of rice cereal, which is grown on irrigated fields. In this regard, there is a need to conduct a study of water resources extracted from water wells for their compliance with sanitary norms and rules, the results of which will be considered in this paper.

  • Development of a protective polymer coating with high hydrophobic and adhesive properties

    The results of the development of a polymer protective coating based on oligopiperylene styrene binder for the protection of concrete and metal surfaces of structures of buildings and structures from the effects of adverse natural and technogenic factors are presented. Modification of this binder with tetraethoxysilane in an amount of 3-20 wt. including allows you to get a protective coating with good hydrophobic properties. Introduction to the composition of 1-12 wt. including tetraisopropyl titanate significantly improves the adhesive and strength properties of the protective coating, which is associated with the formation of bonds between oligopiperylene styrene and tetraisopropyl titanate, due to chemical interaction between the reactive groups of these compounds. The developed protective polymer coating provides good adhesion to the working surface, is easy to apply technologically, the curing of the coating occurs at room temperature, and the improvement of the strength and hydrophobic characteristics of the coating will significantly expand its field of application.

  • Comparison of technical and economic indicators of monolithic buildings of wall and frame structural schemes in calculations for progressive collapse

    The calculation of a multi-storey monolithic building of a wall structural scheme for resistance to progressive collapse is considered. Calculations of the building were made for various operating conditions: normal and extreme (emergency impact — destruction of part of the load-bearing walls of the first floor). Recommendations are given for building protection in case of emergency impacts. It is determined that for buildings with a cross-wall system, the appropriate method of protection against progressive collapse is the method of reserving the strength of load-bearing elements. The increase in the cost of materials is about 2 %. Comparison of technical and economic indicators of buildings of wall and frame structural schemes showed that the cost of protection from progressive collapse of buildings with a wall structural scheme is significantly lower than that of frame
