Diamond drilling is one of the promising and versatile methods of well drilling, which makes it possible to achieve high drilling speeds at great depths of work. At the same time, an expensive diamond tool needs to save a resource. The developed method for managing diamond drilling based on a comprehensive analysis of criteria using the method of a full factorial experiment is effective if it is implemented in real time. Thus, the problem of developing an automated control system for the diamond drilling mode, which makes it possible to save the resource of the tool while ensuring high rates of mechanical drilling speed and minimal power consumption, is topical. This approach will improve the technical and economic results of diamond drilling. The aim of the work is to develop a reliable interactive system of ground sensors and a computer complex that allows implementing automated control of diamond drilling based on a comprehensive analysis of criteria that fully characterize complex drilling and operate in real time.

Purpose: The purpose of this study is to design a highly integrated smart glove to enable gesture acquisition and force sensory interactions, and to enhance the realism and immersion of virtual reality interaction experiences. Design/methodology/approach: The smart glove is highly integrated with gesture sensing, force-haptic acquisition and virtual force feedback modules. Gesture sensing realizes the interactive display of hand posture. The force-haptic acquisition and virtual force feedback provide immersive force feedback to enhance the sense of presence and immersion of the virtual reality interaction. Findings: The experimental results show that the average error of the finger bending sensor is only 0.176°, the error of the arm sensor is close to 0 and the maximum error of the force sensing is 2.08 g, which is able to accurately sense the hand posture and force-touch information. In the virtual reality interaction experiments, the force feedback has obvious level distinction, which can enhance the sense of presence and immersion during the interaction. Originality/value: This paper innovatively proposes a highly integrated smart glove that cleverly integrates gesture acquisition, force-haptic acquisition and virtual force feedback. The glove enhances the sense of presence and immersion of virtual reality interaction through precise force feedback, which has great potential for application in virtual environment interaction in various fields.

The relevance. Diamond drilling is characterized by high rotational speed of the tool at great depths. Such conditions of rock destruction require special control of drilling parameters and their correction. All drilling parameters are interrelated. To achieve the most efficient operation of a diamond rock cutting tool, an optimal mechanism for its operation is required. Analysis of the situation and selection of the required parameters of the drilling mode with diamond tools is the laborious work. This must be done continuously online. The urgent task is the development of the automated control system for diamond drilling in order to rationalize the use of diamond tools. This is possible with the use of modern computer programming technologies. Software algorithm must take into account all the requirements for optimizing the interdependent drilling parameters. The main aim of the research is to develop a control algorithm for a diamond drilling system for its further implementation into software. Objects: diamond drilling, technical and economic indicators of drilling and parameters affecting the results of drilling. Methods: analytical method, full factorial experiment method, modeling method. Results. The main parameters affecting the results of drilling operations are ROP, tool life and power spent on rock destruction. The deepening per revolution as an optimality criterion makes it possible to ensure an acceptable drilling speed and low power consumption while maintaining a high resource of the tool. The control process for diamond drilling consists in analyzing the change at a specific point in time in ROP and power. After the analysis, a decision is made to correct the value of the speed and axial load. A control algorithm for the diamond drilling system was developed. The algorithm can be implemented in an accessible programming language.

Relevance. The PDC cutter reinforced rock cutting tool has proven itself as a rock cutting tool with good performance. As it is known from drilling practice, a tool of this type, with the correct technology of its application, is capable of providing high rates of penetration of wells and resource. Therefore, one of the priority directions in the development of technical means of drilling is to improve the design of the PDC-type tool. New generation drilling tool design methods should be based on an integrated approach to the study of its work at the bottom. One of the main factors affecting the effectiveness of the implementation of rock cutting tools is the bottomhole resistance. A large number of works have been devoted to the study of changes in the physical and mechanical properties of a geological section with depth. And the liquid medium formed at the bottom of the well as a result of drilling is poorly studied. Often, when conducting scientific research, the presence of cuttings in the bottomhole zone is neglected. However, taking into account the peculiarities of the shape and size of the cutting part of the PDC cutters, the displacement of cuttings and continuously moving drilling fluid can have certain density and create a buoyant force acting on the plane of the cutter and, as a result, affect the efficiency of the drilling tool as a whole. Therefore, an urgent issue is to study the properties of the media, consisting of a flushing agent, cuttings and destroyed rock and determine the degree of its influence on the results of the PDC-type drilling tool. The purpose of the research is to determine the degree of influence of the resistance forces of the medium formed in the bottomhole zone of the well on well drilling. Methods: analytical method, computer simulation method. Results. The medium formed in the near-wellbore zone when drilling a well and consisting of rock, cuttings and flushing fluid, which are in different states, has a pushing effect on the cutter, which reduces the size of the deepening. The index of the resistance degree of the described medium is determined by the cutting speed, the angle of the cutter and the density of its components. The results obtained can be used in the design of a PDC-type drilling tool. Changing the angle of installation or the shape of the cutter can help not only to reduce the resistance forces, but also to improve the destructive ability of the tool due to the decompaction of the rock by intensifying liquid penetration into the rock.

The ethylene dehydrogenation catalyst in a certain styrene unit was caked after long-term use. In order to analyze the caking cause of ethylbenzene dehydrogenation catalyst, solubility experiment, baking experiment and X-ray fluorescence spectrum test were carried out. The experimental results showed that the white solid on the surface of the caking catalyst could be dissolved in the water. After the caking catalyst was roasted at 800 °C for 4 h, the white substance was existed. The small granular particles were not crushed easily and were hard. The X-ray fluorescence spectrometer test showed that the white solid was a potassium-containing substance on the catalyst surface. The block formation of the ethylbenzene dehydrogenation catalyst in this unit is caused by the migration and aggregation of potassium during long-term use of the catalyst. The research provided some technical reference for reducing the caking of ethylbenzene dehydrogenation catalyst in the production. [ABSTRACT FROM AUTHOR]

A rational, theoretically proved and empirically verified control system is a condition for optimal management of the drilling process in compliance with the criteria for minimizing the cost of time and material resources. A new generation of rock-cutting tools using PDC cutters (polycrystalline diamante cutters), which are extremely effective when drilling wells for various purposes in medium-hard rocks, dictates the need to develop methods and criteria for optimal control of the drilling process using this tool. The paper presents an analysis of the force interaction between rock-cutting elements, face rock, and drilling mud saturated with slam, highlights the influencing factors and provides dependencies for determining the parameters of rock failure. Empirical verification of the theoretical propositions was carried out based on the data analysis from experimental bit drilling of marble with PDC cutters with a diameter of 76.2 mm, processed using the method of full factor experiment to obtain mathematical models of factors and their graphical interpretation. The method of controlling the drilling process based on the optimal ratio of the tool rotation frequency, axial weight and deepening per one turnover is considered, which allows determining the rock failure mode at the well bottom by indirect signs and choose the optimal values of the drilling mode parameters that correspond to the most optimal conditions in terms of achieving the maximum mechanical drilling speed in conjunction with the rational mode of rock-cutting tool operation. A scheme is presented that contains possible variants of the bit run mode and ways to recognize them by the ratio of the deepening per turnover and the rotation frequency of the rock-cutting tool.
