n: fracture the formation with pressure and inject cement into formation untill the formation pressure keeps at certain specially designated value

n: a squeeze cementing method in which a packer is set to form a seal between the working string (the pipe down which cement is pumped) and the casing. Another packer or a cement plug is set below the point to be squeezecemented. By setting packers, the squeeze point is isolated from the rest of the well. See packer;squeeze cementing.

n: firstly plug back and set down the packer at the section of cement, then lower the packer through pipe and set down on the section of cement, seperates the section of cement from other section, finally squeeze the cement to predetermined spot through the

n: The forcing of cement slurry by pressure to specidied points in a well to cause seals at the points of squeeze.It is a secondary-cementing method,used to isolate a producing formation,seal off water,repair casing leaks,and so forth.
