Development of packer mounting in repair wells

Keywords: packer setting, compressive load, balanced fit, workover wells, downhole equipment

Abstract

Packers are downhole equipment that is essential equipment in well workover operations to protect the production string from reservoir pressure.

The sleeve assembly, which is the main assembly of the packer, requires that during setting the packer is not damaged and does not stick to the inside of the well when running into the well, and that the packer is set correctly. When mounting the packer in the well, it is necessary to ensure full balance.

To ensure balance when setting the packer, in workover wells, care must be taken to ensure that the packer is lowered into the well at low speed. When lowering the packer into the well, it is also necessary to control the descent speed and know the pattern of change in the dependence of the dynamic force on the descent speed. The calculation of the allowable compressive load on the packer equipment used in well repair is considered. A stability criterion is proposed that takes into account bending stresses that occur when a packer is mounted in a well.

Depending on the diameter of the tubing, the critical value of the compressive force acting on the packer was determined, and a new expression was obtained for calculating the allowable load acting on the packer used in the repair well. The critical compression force was calculated depending on the diameter of the well pipes.

Depending on the diameter of the tubing, the numerical values of the critical force on the packer were determined. It was found that the value of bending stresses as a criterion for static stability corresponds to 15% of the yield strength when the packer is mounted in a repair well.

When mounting the packer in repair wells, care must be taken to ensure that the packer is lowered into the well at low speed to ensure balance
