 ABSTRACT

This article, devoted to methods for assessing the technical condition of drill rotors, will help to consider the problem of servicing industrial equipment. The relevance of this work lies in the fact that in today's time, with the development of industrial sectors, both in our country and in other countries, there is a need for new and effective approaches to assessing the technical condition of equipment. Especially with the expansion of the boundaries of the oil and gas industry, the number of unexplored deposits is increasing. To process such deposits, there is a need to introduce new methods of maintenance. In order to increase the productivity of equipment that works for a long time, sometimes continuously, it is important to adhere to certain service methods. The aim of the work is to study the available methods for assessing the technical condition of drill rotors and propose a new integrated approach that combines the available indicators and criteria of known methods. This article discusses in detail the methods for assessing the technical condition of drill rotors, their characteristics are studied. The objectives of this work are to analyze the available methods for assessing the technical condition of drilling equipment, to determine the procedure for establishing the noise and vibration characteristics of rotors, to develop criteria for assessing the technical condition of the rotor. The article also analyzes the factors affecting the operation of drill rotors in operating conditions. Having studied the existing methods, a new integrated method is proposed, which, through a point approach and the choice of a specific method, based on the available data on the unit, will ensure higher reliability and longevity of the drill rotors used. The use of an integrated method is based on the calculation of all important points that are relevant to the object under study. The proposed method will have to reduce errors and malfunctions of drill rotors, increase the accuracy and service life of the equipment. The choice of an integrated method will help to ensure the continuous operation of drill rotors in industrial enterprises.

 ABSTRACT

 In the presented article, the analysis of the effect of the dynamic load falling on the polished rod of the sucker rod pump unit on the normal function of the operating unit during the oil extraction process was carried out. The general formula for the damage caused by the impact of the pump's wellhead packing seal has been derived. The dependence graph of damaged work on the length of the packing seal and the Poisson's ratio of the material was made.

Due to the dynamics of the frictional force generated in the packing seal of the stuffing box appropriately located below the suspension point of the rods, its forced cyclic movement occurs as a result of the impact transmitted to the system which consists of an incompressible fluid column, and the elastic rods. This requires the investigation of the dynamics of the rod pump associated with the probability of unpleasant situations such as the possible resonance occurrence in the specified system, the time between repairs, and the reduction of the working coefficient of the pump, in this regard.

At the same time, the questions such as the coefficient of friction depending on the selection of the material of the packing seal, the reduction of the dynamic accumulation of the load on the system, and the saving of electric energy are also important. It needs to be considered that the operation process is accompanied by a certain energy loss. It should be taken into account that even a small reduction in energy loss can manifest great economic benefits. It should be noted that some issues encountered in the process of operation of oil wells through the rod pump and depending on certain arguments affecting this process were also resolved by those experts.

Keywords: oil production, frictional force, sucker road pump, dynamic load, logging operations, logging cable, separator, energy loss, wellhead packing seal.

ABSTRACT
In the production of oil by downhole rod pumps, as a drive, both in Azerbaijan and abroad, balancing one-arm and two-arm pump jack are most often used ones. In this article the goal is - a comparative study of the advantages of one-arm pump jack over two-arm pump jack. For that, the calculation of the main parameters was maid – displacenemt, speed and acceleration of suspension poin of rods and built comperative graphs for commercially avaible deaxial pump jack type of SKD8-3-4000 and the proposed construction of a one-arm pump jack. There are existing options, for holding a one-arm pump jack on the weight of the balancer when changing the stroke length of the suspension point of the rods that reviewed. Options for improving the one-arm pump jack are proposed.

Keywords: pumping unit, balancer, pump jack, one-arm, two-arm.

 ABSTRACT

 A hydraulic device that is used to suck up liquid, move it under pressure or pump it, is called a pump. As a rule, any movement of a liquid by similar aggregates is carried out due to the transfer of potential or kinetic energy to it. Depending on the technical indicators, different types of pumps are used. At the same time, they differ in efficiency, power, volumes of fluid pumped per unit time, maximum head and resulting pressure.

The most used group of pumps are vane pumps. Their distinctive feature is the impeller rotating in a fixed housing, equipped with blades. Depending on the warehouse of the impeller and the conditions for moving fluid through it, vane pumps are divided into centrifugal and vortex.

With a centrifugal pump, liquid is supplied due to the centrifugal force that appears when the impeller rotates. She is carried away by the blades and, under the action of centrifugal force, moves from the middle of the wheel to the edges along the blades. The blades of the impellers are bent in the direction of rotation backwards. The number of blades is usually from 6 to 8 pieces. But special pumps for impure liquids, in order to increase the cross section of the channels in the wheel, are installed with a smaller number of blades from 2 to 4 pieces.

Centrifugal pumps are usually installed above the liquid level in the receiving tank, so they must be filled before use. The pump is filled with a check valve on the suction line through the filling funnel until the gas is completely expelled from the suction pipeline and the pump housing. In the absence of a check valve, for filling, air is forced out of the pump housing with the valve closed by a special vacuum pump. The same is done when filling large pumps. Centrifugal pumps are characterized by a rather high efficiency, compactness and durability of use.

Based on the numerical modeling of hydrodynamic processes, a substantiation of adjustment of the design of the working wheels of centrifugal pumps is given. Mathematical modeling of the fluid flow in the running part of the centrifugal pump is performed. The results of the CFD calculation are analyzed, after which an experimental work wheel is created, and its tests are carried out. There is a process of comparing a serial and experimental pump.

Keywords: Centrifugal pumps, numerical modeling, mathematical model, energy characteristics, hydrodynamic processes, dynamic characteristics, power engineering, working wheel, working fluid, working wheel vanes.
