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.
