Equilibrium well killing as a factor of wells productivity preservation
The article describes the development and field introduction of a well killing technique that is different from traditional method of wells killing. The essence of the technique lies in the fact that before conducting geological-technical measures or when replacing the submerged pump, a well killing with the excessive pressure in its mouth or gas manifestation is made by the killing liquid, compounded by its composition with the formation fluid, through the lift pipes of the well excluding a filtration into the productive formation.
