Cement-filled casing The outer packer is a tool that eliminates the need for an inner tube to expand and pack the grout. Can make a permanent bridge between the casing and the wellbore blocking, to prevent casing fluid channeling after cementing. At the same time improve casing centering degree and stability, to improve cementing quality have obvious effect, to solve packer seal aging limitation problem.
