ANALYSIS OF THE STATE OF SERVICEABILITY IN THE PROCESS OF WEAR OF ELEMENTS DURING THE OPERATION OF OIL AND GAS PRODUCTION EQUIPMENT

The generalized indicator of useful use, depending on the state of individual elements of oil-producing equipment, characterizes the ability of this equipment to perform its function during operation at optimal working time. The generalized indicator of the useful use of operational equipment can be described as the calculated sum of the indicator of the useful use of individual equipment elements. If, during operation, the oil-producing equipment retains its operability due to frequent replacement of its structural and non-structural elements, then such operational equipment is considered by users as outdated. Operating equipment can be divided into 6 categories according to the indicators of suitability. The article analyzes the state of useful use of equipment and, as a result, the total utility of equipment is calculated in accordance with the indicators of useful use by category, and graphs of changes in the state of useful use are constructed. Based on the study of the graphs of the useful use of equipment, it was proposed to conduct an analysis in the following areas: • Evaluation of the design and technological perfection of the equipment by users according to important new parameters. • Determination of equipment compliance with wear standards during operation. Keywords: structural element, wear theory, the usefulness of jam, categories, schedule of changes, reliability.

INCREASING THE CURRENCY RESISTANCE OF CYLINDER-PLASTING OF PYSTON PUMPS BY PLASMA METHOD

The article examines the study of increasing the wear resistance of the cylinder-sleeve of a piston pump using the developed technology of plasma spraying. Wear-resistant and durable coatings of nickel, chromium, molybdenum and tungsten were obtained on the surface of the piston pump cylinder-sleeve. A graph of the dependence of the coating thickness depending on the surface hardness of the cylinder-sleeve is presented. According to the graph, depending on the hardness, you can determine the wear resistance of the coating surface of the cylinder-sleeve.

RESEARCH OF WORKING BENEFITS OF BEARINGS APPLICATION OF MATHEMATICAL METHOD

It is known that the service life of oilfield machines and mechanisms is to a certain extent determined by the operability of friction units, the operation of which, as a rule, occurs under severe conditions (heavy loads, abrasive aqueous medium, etc.). It is also known that the determining parameters in the units of machines and mechanisms (lubricated with water) with polymer elements are specific load, sliding speed and relative clearance. In the field, these factors affect the coefficient of friction together, therefore, the study of their influence [µ = f (p, ʋ, ψ)] on the coefficient of friction is possible only with the use of mathematical modeling. We have studied the nature of the joint influence of the main operating parameters on the performance of the ison thermoplastic elastomer plain bearings. Keywords: Operation, polymer elements, field conditions, bearings, sliding speed.

RISK MANAGEMENT IN MAQISTRAL GAS AND OIL PIPELINE SYSTEMS WITH POTENTIAL COST CONSTRAINTS

The problem of managing technical and technological risks in main gas and oil pipeline systems, subject to the possibility of limited funds allocated for the prevention and elimination of the consequences of accidents, is considered in the form of a semi-Markov decision-making model for a controlled Markov process in continuous time with the criterion of the maximum average discounted income. To find the optimal nonrandomized Markov stationary strategy, a procedure is proposed based on reducing the formulated fuzzy problem to an equivalent Boolean programming problem with deterministic constraints. To solve the resulting system of inequality constraints, an algorithm has been developed for finding basic solutions for an arbitrary number of accidents and measures to eliminate them. The numerical implementation of the proposed approach is implemented for the real problem of risk management in the main gas pipeline with unclear cost constraints. Keywords: semi-Markov decision-making process, Markov stationary strategy, feasibility optimization, basic solutions to inequalities.

RESULTS OF THE APPLICATION OF NEW TECHNOLOGIES IN INCREASING RESOURCES IN HIGH PRESSURE DRILLS

In oilfield practice, as well as in the transportation of oil and gas, great importance is attached to the use of high-pressure valves. Since the demand for this fleet of equipment is growing, it is especially important to increase their resources and reduce their cost on this basis. Along with the constructive and technical measures taken in this direction, serious attention should be paid to improving the choice of materials for the manufacture of parts and their production technology.. The article is devoted to the discussion of the results obtained when using the coquille technology for the manufacture of parts made of low-alloy chromium-molybdenum steel Keywords: high-pressure gate valve, body, gate, seat, hardness, wear.

ELASTOPLASTIC PROBLEM FOR PERFORATED PLATE IN TRANSVERSE SHEAR

A solution is given to the problem of transverse shear of a thin plate clamped along the edges of the holes and weakened by a doubly periodic system of rectilinear through cracks with plastic end zones collinear to the abscissa and ordinate axes of unequal length. General representations of solutions are constructed that describe the class of problems with a doubly periodic stress distribution outside circular holes and rectilinear cracks with end zones of plastic deformations. Satisfying the boundary conditions, the solution of the problem of the theory of shear plates is reduced to two infinite systems of algebraic equations and two singular integral equations. Then each singular integral equation is reduced to a finite system of linear algebraic equations. Keywords: perforated thin plate, straight cracks with end zones, transverse bending, plastic deformation zones.

SOMEONE FIRST IN THE WORLD OF LOGIC-LOGISTICS

In the article, in contrast to those who consider only one of the two historical figures with identical functions and attribute the first mention of "Logistic" to the 9th-10th centuries. AD [1], the author, studying all the facts, claims that the formation of another personality (mantig-vizier), confirmed by historical documents, is more ancient and belongs to the 17-16 centuries. BC NS. [2]. Thus, based on the event, which is described in the holy books of the scriptures Torah, the Bible and the Koran and dated 1864-1754. "Interpretation of the Pharaoh's dream", and in the literary aspect, a more common work like "Yusuf and Zuleikha" [3], the author in the economic and technical aspect proves that the founder of the above identical functions - frugality, the art of calculation and logical thinking, is "Pharaoh - Prophet Yusuf" Keywords: logistic, logic, talent, security, reliable, guaranteed, stocking (purchase), distributes.

IMPROVED VALVE DESIGN SUSTAINABILITY RESEARCH

The issues of tightness and abrasion resistance of the new design of the ZMS-type valve are considered. An analytical expression was obtained to determine the relative pressure generated across the check valve of the improved valve. Checked the condition of the valve tightness and abrasion resistance. The new valve design was tested at JSCO “NEFTGAZMASH”, and as a result of the tests it was found that the new valve fully complies with these conditions.
