摘要： A small diameter stage cementer assembly 10 and a hydraulically operated packer collar stage cementer 110, including a cementer housing 12 for interconnection with a casing string 14 positionable in a slim-hole wellbore for a cementing operation. The cementer housing 12 including a seat 11 for receiving a lower, drillable portion 335 of an opening sleeve assembly 135 after the upper drillable portion 235 of the opening sleeve assembly 135 has been drilled out. The lower, drillable portion 335 wedges into engagement with the seat 11 to prevent rotation of the drillable portion 335 during drill-out, such that the lower portion 335 may be drilled up using a small diameter bit and drill string, and accommodating a reduced weight on bit. The packer collar embodiment includes a hydraulically actuatable packer 70. In the packer collar embodiment of the stage cementer 110, cementing ports 34 are provided separate in a separate axial plane from hydraulic inflation ports, such that the secondary opening device or rupture disks may be securely positioned within the cementing ports. Thereby, a relatively thin-walled outer case 20 may be utilized for the hydraulic passageway 130 to the packer 70, without having to increase the case outer diameter to accommodate positioning a rupture disk in the case. The stage cementer housing may be sized for use with a casing string 14 with a nominal OD of 4½ inches or less. An improved method of operating a stage cementer is disclosed.

摘要： A tubular tool body carried at the end of a drilling rig top drive is received within a drill string being used as a landing string to position casing in a wellbore. External threads on the tool body can be mated with the box threads of the drill string to secure the top drive and drill string together for simultaneous drill string movement and fluid circulation. An annular seal carried about the tool body engages and seals with the internal wall of the drill pipe to prevent drilling fluid leakage when the tool body is received within the drill pipe without thread engagement. The tool has an internal check valve that opens to allow back flow of drilling fluid that may be displaced from the drill pipe as the pipe is lowered into the well. The check valve prevents standing fluid in the top drive from spilling onto the rig floor when the tool is withdrawn from the drill string. Pump pressure applied through the top drive axially moves the check valve against a biasing spring to open a bypass through the wall of the tool to permit forward circulation through the drill string and casing. The spring bias force is sufficient to withstand the hydrostatic force exerted by the standing column of fluid in the top drive and associated piping.

摘要： An improved float valve according to the present invention includes a packer 10 for positioning within a joint of the casing C while at the surface of the well, the packer including a float valve receptacle therein for at least partially receiving a float valve. The float valve body includes a valve seat 56 and a valve member 54 is positioned for selective engagement and disengagement with the valve seat. A guide nose 58 may be optionally provided for positioning within the casing joint between the valve body and the pin end of the casing joint. The float valve body may be reliably fixed and sealed to the packer body. After the packer setting operation, the casing joint and the packer and the float valve may then be positioned as an assembly within the well.

摘要： An liner hanger setting mechanism is provided. The setting mechanism of the present invention is basically comprised of a tubular pump down plug receptacle having a plug seat defined therein. A cylindrical pump down setting plug having a central flow passage and a rupturable member disposed therein to prevent flow therethrough is dropped into a work string and the tubular plug receptacle. The pump down setting plug will engage the plug seat and pressure can be increased to the setting pressure required to set a hydraulically actuated liner hanger. The pressure can then be further increased to the rupture pressure of the rupturable member to provide for full bore flow through the pump down setting plug.

摘要： 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.
