Claims
- 1. A well completion tool comprising the combination of:a) a cementing valve having a cement flow channel from an internal pipe bore into a surrounding well annulus, said flow channel being opened by a fluid pressure displaced first sleeve element and closed by a fluid pressure displaced second sleeve element; b) a fluid pressure engaged well annulus barrier surrounding said pipe bore and displaced along said pipe bore from said cementing valve; c) a production valve positioned along said pipe bore from said annulus barrier in a direction opposite from said cementing valve, said production valve having a rupture opened flow channel from said surrounding well annulus into said pipe bore; and d) a pipe bore a-plug seat positioned along said pipe bore from said production valve in a direction opposite from said annulus barrier.
- 2. A well completion tool as described in claim 1 wherein said cementing valve, well annulus barrier, production valve and plug seat are serially aligned toward the well bottom.
- 3. A well completion tool as described in claim 1 wherein said combination further comprises a production packer positioned along said pipe bore from said cementing valve in a direction opposite from said annulus barrier.
- 4. A well completion tool as described by claim 1 wherein said cementing valve further comprises a closure plug seat positioned in said pipe bore along a direction from said cement flow channel opposite of said well annulus barrier.
- 5. A well production string comprising a production tube having an internal flow bore, said production tube suspending the operative assembly of:a) a cementing valve having a cement flow channel from an internal flow bore into a surrounding well annulus, said flow channel being opened by a fluid pressure displaced first sleeve element and close by a fluid pressure displaced second sleeve element; b) a fluid pressure expanded well annulus barrier surrounding said production tube and displaced along said production tube from said cementing valve; c) a production valve positioned along said production tube from said annulus barrier in a direction opposite from said cementing valve, said production valve having a rupture opened flow channel from said surrounding well annulus into internal flow bore; and d) a pipe bore plug seat positioned along said pipe bore from said production valve in a direction opposite from said annulus barrier.
- 6. A well production string as described in claim 5 further comprising a production packer positioned along said flow bore from said cementing valve in a direction opposite from said annulus barrier.
- 7. A well production string as described in claim 5 further comprising a well fluid production screen operatively positioned along said flow bore from said plug seat in a direction opposite from said production valve.
- 8. A well production string as descried by claim 5 wherein said production tube further comprises a closure plug seat positioned in said internal flow bore from said cement flow in a direction opposite from said annulus barrier.
