Author:

Mammadov Vasif Talib and Suleymanova Arzu Javanshir

Subject Area:

Physical Sciences and Engineering

Abstract:

Solution of the sparital task on tension-deformation condition of biaxial loaded well packer is considered in the article. Koshi method for variations of the components of tensor deformations in complex loading in the well has been used. The theory of plastic flow has also been applied, borders of plastic zone at the period of packing deformation have been determined and some variants in the particular case for satisfying stabilly conditions of the sealing have been solved. The obtained results are compared with the results of the works carried out by other authors.
