In the drilling of wells, cementing of protective pipelines, development of productive horizons, as well as in operation, wells need to be divided into permanent or temporary areas. More advanced than these processes is the use of packing devices in the technological separation of layers and the insulation of protective belts. For example, delivery of the buffer mixture to the absorption zone by packer-mounted drill pipes saves 40-60% of time and reduces material consumption by 1.5-2 times compared to previous non-packer technologies.

Keywords: packer, cuff, protective pipeline, sliding, sealing.

 Аbstract

At present, the compressor industry of the oil sector of Azerbaijan is one of its leading links. If by the end of the 20th century the number of wells using the gas-lift method of production was about 42-46%, then by the end of 2019 it exceeded the 50% level. Compressors are an integral part of this technological process and require a strict improvement in the technical level of their safe operation. Therefore, improving the technical and economic performance of the compressor unit is an important task. This work is devoted to the study of design features and the main causes of valve failures in reciprocating compressors, as well as an assessment of their safe operation.

Keywords: reciprocating compressor, reliability, valve, safety, gas-lift extraction method.

 Аbstract

This article is devoted to one of the important problems of mechanical engineering, including processing by cutting and deploying in sintered antifriction powder material in optimal modes with maximum performance. The study was conducted for small diameter cylindrical bushings. Processing of bushings was carried out by reamers from high-speed and carbide tools on materials from porous powder and cast iron. It is established that the temperature of the tools should not exceed the permissible upper limits, for pressing the bushings, it is necessary to use planting with small strains in the cold state.

Keywords: engine valve, bushing, powder material, cast iron, reamer, cold pressing.

 Аbstract

Present days’ high market competitiveness requires wide range of design and production solutions to ensure reliable and efficient usage of various types of machines and equipment. From the different perspective provision of equipment with effective preservation and maintenance characteristics is a critical factor to be taken into an account. Arising from these factors, systematic approach for solution is require together with identification failure related to maintenance and operability of the equipment. Various pumps are used in oilfields and particularly their hydraulic parts are among the equipment sets, requires frequent execution of maintenance and modernization works. The article discusses the issue of increasing the reliability of the hydraulic part of oil field pumps.

Keywords: oilfield pump, hydraulic part, reliability, modernization, parameters of statistical distribution.
