摘要: A packer assembly features one or more elements that preferably swell when in contact with well fluids and have a feature them responds to an applied load given direction by retaining such boost force locking mechanism. single element can two mechanisms respond forces from opposed directions. Friction for adhering the mandrel is enhanced surface treatments between still allow operate.
