ABSTRACT:
Surface packer and method for using the same. An annular body is mounted on the upper end of a string of casing which extends above a drilling rig platform. An annular seal is received within the body at the upper end thereof and may be sealed against the radially outer surface of a string of drill pipe which is lowered therethrough into the casing. A radial circulation port is formed in the body beneath the annular seal. In a cementing operation, a string of drill pipe is lowered in the casing to the lower end thereof and the annular seal is sealed thereagainst. The pipe-casing annulus is pressurized and cement is pumped into the drill pipe for cementing the casing into the well bore. In one embodiment, the annular seal is of the inflatable type which permits vertical and rotational manipulation of the pipe string while maintaining the seal thereagainst.
