Y111-115/148 Packer

  1. Usage
    Y111-115/148 Packer could be used to stratified well testing, oil recovery, water plugging and acidification. This kind of Packer could work with slip type Packer or backup slip together.
     
  2. Structure theory
    Running string tools according to setting height and space between tubing and top flange. Below Packer, there is tailpipe, slip type Packer or backup slip as support. String weight compress rubber element to increase the ID, which could block and seal oil or casing annular. Pull string upside, rubber element reinstate again.
    Feature: increase shear pin structure, in order to avoid wrong setting. When running string tools, wrong setting would happen if Packer stopped to move down and under string weight. Shear pin structure could prevent wrong setting if running string tools and cut shear pins to down into well.
