Abstract

Packer is a device designed for disconnection of joints during operation, repair and maintenance of oil and gas and oil wells, for insulation of technological pipelines around the impact of the environment. Packers can be used for widely used in technological operations such as hydraulic fracturing, acid-thermal processing of plastics, insulating works, hydropeskostruynoy perforation and others. Packers are used for vertical separation of parts of oil wells and closure of damaged parts of the cable body. It is calculated for the work in the well for several hours (for example, during fracturing), for several months (when hitting the heaters) or for several years (for example, packers for various extraction methods of extraction of oil). Pressure drop, perceived by packers, can be from 7 to 70 MPa. During the operation of the well, the temperature of the surrounding medium can fluctuate from 40 to 100°C, and in some cases reaches 300-400°C under the influence of heat on the formation. The environment in which the packer operates usually causes corrosion of the metal, and the content of oil and gas requires a thorough selection of packaging material. During mining, packers are usually installed in the casing well and work on the pipeline. The packers are presented with the following basic requirements for ensuring reliable work in accordance with their purpose:

  • the packer has to withstand the maximum pressure drop under extreme conditions, called "working pressure";
  • The packer itself must have an outside diameter that ensures the optimal gap between the wall of the operating rope and, after that, a tight connection.

Keywords: packer, machine building, plug, pipe connector.

Abstract

The performance of the heat exchanger network (HEN) in a plant is an important aspect of energy conservation. “Pinch” technology and mathematical programming techniques offer an effective and practical method for designing the HEN for new and retrofit projects. The fluid catalytic cracking (FCC) is a dominant process in oil refineries and there has been a sustained effort to improve the efficiency and yield of the unit over the years. HEN optimal design in FCC process is an essential element in reducing the cost and improving the process as a whole. The objective of this work is to introduce a systematic procedure for designing optimal and flexible FCC-HEN that incorporates variations in feed flow rates and specs and on same time considers different schedules imposed on the process.

Keywords: heat exchangers, fluid catalytic cracking, design of network, oil refinery, heat recovery systems

Abstract

Determination of the composition of materials and methods of obtaining products from them for seals of pumping units.  A powder composite material “iron-cast iron” is proposed for the manufacture of seals used in friction units of pumps. The necessity of choosing cast iron powder for obtaining compositions of this type is shown. As a powder of cast iron,a special gray cast  iron with interdendritic point graphite is proposed. The cremical composition, properties of gray cast  iron and the properties of powder compositions obtained by cold pressing and sintering from five charge compositions. It is noted that due to the fact that the seals must have special tightness, they must be subjected to subsequent compaction.

Keywords: iron-castiron, composition, interdendritic point graphite, pearlite, chemical composition, strength, powder charge.

Abstract

Depending on the severity of the accidents, repairs are carried out in the boreholes, mainly through the destruction of accident facilities. A widespread variation of this method is the continuous removal of a thin layer of metal shavings from an accident body, followed by the process of removing the crushed rock mass to the surface with a washing-cooling liquid called milling. Milling processes (for example, pump-compressor pipes, pump rods, etc.) are very complex in nature and are accompanied by a variety of physical phenomena, the mathematical description of which (especially the processes of friction and wear) is very difficult.

Keywords: milling, cutting process, dimensionless combination, limit torque.

Abstract

The article states that the following fluids of various nature are widespread in nature, which were determined as a result of experimental research in the science of rheology: Newtonian, non-Newtonian, viscous-plastic, dilatant and other fluids. For each of these fluids, the laws of friction are also presented, that is, Newton's law of friction, Bingham-Shvedov's law of friction, Maxwell's, Sesson's, Z.P.Shulman's laws of friction. Filtration laws were also introduced, which obey some of these laws, that is, the Generalized Course Law; for others, the laws of filtration are unknown. One of the co-authors of the article promoted a new idea that the laws of friction and the laws of filtration of liquids have a certain analogy and using it, on the basis of the law of friction of a liquid, one can determine the law of filtration of the same liquid.

Keywords: law of friction, law of filtration, analogy, Newton's law of friction, Darcy's law of filtration, Bingham-Shvedov's law of friction, generalized Darcy's filtration law, Caesson's filtration law, Z.P.Shulman's filtration law.
