This article is devoted to the research and implementation of methods for ensuring water insulation works (WIW) in the oil sector using hydrophobic emulsions. In the context of modern requirements for environmental safety and efficiency of production processes in the oil industry, where water can become a source of problems, the introduction of innovative materials and technologies plays an important role. Conducting laboratory studies of hydrophobic emulsions for WIW in the oil sector is a multiprocess approach, starting from the initial assessment of the chemical component and ending with thorough testing for compliance with the requirements of specific operating conditions. The analysis evaluates the physico-chemical properties of the emulsion, such as density, viscosity, pH level, degree of dispersion, as well as its adhesive and cohesive characteristics. Special attention is paid to the study of the surface properties of hydrophobic emulsions, since their ability to form stable water-repellent coatings directly affects the effectiveness of protection against water exposure. To do this, tests are carried out on wettability, contact angle, adhesion to various types of surfaces, which allows us to determine the optimal conditions for the use of emulsions in specific situations. The article describes the principles of action of hydrophobic emulsions in the context of waterproofing works, emphasizing their ability to create a protective barrier, preventing moisture penetration into oil facilities. The paper presents the results of laboratory studies demonstrating the effectiveness of the use of hydrophobic emulsions in various operating conditions. The article discusses the technical aspects of the use of hydrophobic emulsions in the WIW process, analyzes their resistance to various environmental factors, and also considers the prospects for the development of this technology in the oil industry. The results obtained can be useful for specialists dealing with water insulation in oil companies, as well as for the scientific and engineering community interested in the development of innovative technologies in the oil sector. The purpose of this article is to analyze laboratory research and provide recommendations on the use of polymer composition.

The drill bit in the oil and gas industry plays a key role in the drilling process, but its operation in the field, filled with difficulties and dangers, emphasizes the need for careful study of its behavior. This equipment, which is the head of the well, is forced to face various challenges during drilling, where danger can await at every step. However, special attention should be paid to those cases when the drill bit collides with crumbling rocks. In conditions of high pressure and friction associated with drilling, the drill bit is subjected to significant loads. These conditions can lead to damage and breakage of equipment, which in turn creates additional risks for workers on site. Understanding the behavior of a drill bit in crumbling rock is becoming an extremely important aspect to ensure the efficiency and safety of field work. The analysis of the technical characteristics and mechanisms of the impact of the drill bit on crumbling rocks makes it possible to develop more reliable and durable tools capable of withstanding extreme conditions. This, in turn, increases drilling efficiency, reduces the risk of industrial accidents and ensures safer working conditions in the oil and gas industry.

This article is devoted to the study of the process of crack formation in rocks during hydraulic hammer drilling. Analysis of the manifestation of cracks in rocks during hydraulic percussion drilling is a key aspect of research aimed at the optimization and efficiency of this drilling method. The article presents a comprehensive analysis of the mechanisms of crack formation in rocks under the influence of hydraulic shock waves, identifying factors influencing their development and propagation. The work highlights the basic principles and mechanisms of hydraulic percussion drilling, and also analyzes the factors influencing the formation of cracks in rocks during this drilling method. In addition, various parameters such as water pressure, impact velocity, tool type and rock characteristics are considered and their influence on fracture formation. The paper presents numerical modeling and calculation methods used to analyze the factors influencing the formation of cracks during well drilling. Basic parameters are considered, such as well depth, type of drilling equipment used, physical and mechanical properties of the rock, drilling fluid pressure and others. Examples of numerical calculations and modeling are given, as well as an assessment of the influence of various factors on the formation of cracks in rock. The purpose of this article is to summarize current information on the formation of cracks during the hydraulic percussion drilling method. The scientific significance of this study lies in the possibility of predicting and controlling the formation of cracks during hydraulic drilling, which contributes to more efficient use of resources and improved drilling safety. The results obtained can be used in the practice of geological exploration and mining work to optimize drilling processes and improve the quality of mineral extraction. Understanding the processes of formation of cracks in rocks with this drilling method will allow optimizing its use, improving control over the process and ensuring more efficient and safe extraction of minerals from the bowels of the earth.
