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.
