  • Patent number: 5845711
    Abstract: The apparatus and method for injecting coiled tubing downhole includes a connector member disposed on the end of the coiled tubing and supporting a downhole tool. A packer member is releasably connected to the connector member. The packer member includes a pack-off element and slips for releasably engaging the outer pipe string through which the coiled tubing is being injected. Seals are provided on the packer member for engaging the outer circumferential surface of the coiled tubing. A fluid passageway extends through the connector member for communicating the packer member with the coiled tubing. Fluid pressure is applied through the flow bore of the coiled tubing. The fluid pressure is applied through the fluid passageway to actuate an actuator member in the packer member to set the pack-off element and slips. Thus, upon actuating the packer member, the annulus formed by the coiled tubing and outer pipe string is closed.

  • Patent number: 5704393
    Abstract: The apparatus and method for injecting coiled tubing downhole includes a connector member disposed on the end of the coiled tubing and supporting a downhole tool. The connector member includes a dual check valve in the fluid passageway which allows fluid passage to actuate the packer member and closes the fluid passage after the connector member is disconnected from the packer member. The connector member may also include a valve member which allows circulation down the flow bore of the coiled tubing. The packer member includes a valve for the passage of well fluids between the packer member and coiled tubing.
