The results of research on the design, manufacture of parts and assembly of rolling-cutter drill bits with multiply reduced tolerances on the main output parameters such as radial, face-motion vibration, as well as constancy of size along the bit diameter are presented. The size of these tolerances, regulated by the API International Standard, is calculated only in tens of millimeter shares, however, it has a very large impact on drilling performances, namely average penetration and mechanical speed, which means the cost of penetration when drilling millions of meters of wells. For many years, scientists from leading drill-bit companies in the world have tried to solve the problem of reducing the size of the above-said tolerances. The smaller is the size of these tolerances, the higher is the value and stability of drilling performance, the prestige of sales, significantly higher the price of drill bits.

 

Keywords: rolling-cutter drill bit; drill-bit leg; rolling-cutter drill bit; section; bases for treatment; final treatment; welding electron beam gun; vacuum chamber; scanner; tolerance for radial and face-motion vibration; constancy of a bit size.

The paper discusses tribotechnical factors affecting the structural and mechanical properties of welded joints of austenitic steels. Changes in the structure of the metal that occur during manufacturing, including its phase composition, require appropriate design and technological support for the correct selection of material design and correction of technological processes. The coil of chromium-nickel austenitic steel, designed in overall and mounting dimensions to replace the foreign analogue in the lean sorbent furnace of the associated petroleum gas preparation unit, was selected as the object of study. Site inspection included analysis of technical and operational documentation, visual measurement control and identification, special attention was paid to magnetic control of the ferritic phase of welded joints. It is shown that in the manufacturing process and during operation, control over changes in the structure and phase composition of the metal is necessary, since they can undergo noticeable changes under the influence of various tribotechnical factors.

 

Keywords: coil of the furnace for the associated petroleum gas preparation plant; tribotechnical factors; magnetic control; control of the ferrite phase; austenite; nickel-chromium steel; weld.

The article presents the results of research conducted by Gubkin University and KTH Royal University of Technology on the possibility of autonomous power supply for remote objects. The severity of the problem is associated with the implementation of large oil and gas projects in Eastern Siberia and the Far East, such as, for example, the Eastern Gas Program of PJSC "Gazprom". Such projects could significantly increase the export of Russian hydrocarbons to the promising markets of the countries of the Asia-Pacific region. Based on the analysis, an approach to solving the problem of energy supply of industry facilities using renewable energy sources is proposed.

Underestimation of the danger of bacterial destruction leads to the loss of technological properties of drilling fluids based on biopolymer, corrosion of a drilling tool, reduced injection capacity of a well, poor filtration characteristics of rocks, reduced oil recovery due to clogging of the reservoir with accumulations of living and dead bacterial cells and their vital products, including sediments of calcium, sulfur, magnesium, iron, mucus and polysaccharide bio-formations. The paper describes methods for studying the biodegradation processes of polysaccharide reagents used in the RUE PA "Belorusneft", as well as a method for determining the optimal time for a drilling fluid treatment with a biocidal additive in order to prevent biodegradation of the entire system.

The paper considers an important problem relating to the efficiency of using the energy introduced into each element such as the Venturi pipe, i. e. what the energy efficiency magnitude is. The answer can be obtained by comparative studies of the specific surface area of bubbles in a gas-liquid system and mass transfer coefficients in a pipe with a periodically varying cross-section and in a cylindrical pipe under other equal conditions. When processing capillary-porous particles, acceleration of mass transfer inside a particle can be facilitated by pressure pulsations, and from the outside, liquid periodic pulsing renewal near the particle surface.

The proposed method for the excitation of pulsations in a moving fluid stream can be used for the processes of crushing drops and bubbles in the continuous liquid phase, since favorable conditions arise here – significant amplitudes of pressure, velocity and acceleration at hundredth order of tens of Hertz. The combination of power factors arising in an element such as the Venturi pipe can serve as a powerful means of deformation, crushing of dispersed inclusions, contribute to wave formation on their surface, and improve internal mixing, and in general should contribute to the acceleration of mass transfer processes. These same factors can help acceleration of mass transfer during processing of solid impermeable and capillary-porous particles.

The paper presents a multiple-factor goal planning model of measures for control system of compressor stations technological pipelines integrity of (CS CSTPI) that consider completeness of technical inspection data, pipeline damage by various groups of defects, financial and technical constraints. CS CSTPI model ensures procedural uniformity during evaluation, forecasting, monitoring and management of the pipelines technical state target indicators. Regulatory framework is based on the experimentally proved data on hazardous level and propagation rate of pipelines operational defects, inspection tool parameters, inspection data verification results, pipeline operation modes and conditions.

The paper highlights specifics of robotic inspection, verification of inspection data, CS pipelines technical condition evaluation and forecast. The authors provide practical recommendations on how to consider the time of damage propagation, optimize CS pipeline repair methods on the basis of corrosion and stress corrosion physical models.

The authors conceptualize a brand new tool of CS pipelines integrity management – the Intelligent for CS pipelines technical inspection support that applies Big Data and Machine Learning technologies. Intelligent System is a universal software package that provides 3D-visualization of the compressor station pipelines complex structure, inspection data and the results of their analysis. Intelligent System, for the first time, implements processes of machine recognition of pipeline elements and defects images based on defectograms transmitted by in-line automated diagnostic tools (ADT), and prediction of pipeline damage by defects not detected by ADT.

The article presents an approach to assessing the economic efficiency of projects for monitoring the technical condition of technological equipment for oil and gas facilities. A mathematical model has been developed for this assessment. It is shown that the results of calculations are determined not only by the technical characteristics of the equipment and the capabilities of the instrumental system for monitoring the technical condition, but also by the "operational context": financial and economic indicators of the enterprise, the price situation for products, the intentions of the object owner, etc.
