Packer design research used in hydraulic fracturing

Abstract

The purpose of the packers is determined by the specific technological tasks. The design of a packer and the principle of bringing it into action provide protection from ealy wear during the tripping process. In addition, the design of a packer ensures manufacturability of its use and reliable control over the work in the well during the hydraulic fracturing, regardless of the depth of the installation. The experience with the use of packers for the test beds showed that in most cases packer items become inoperative due to the destruction of the lower part of the rubber element. In practice, the isolation annulus packer with different ways of planting is important and necessary to ensure reliable fixing of a packer at the place of installation in the borehole. It happens due to the use of anchoring unit and different designs of seals of packers
