Load-monitoring sensor proximate to a shifting device
A downhole tool includes a shifting device and a load-monitoring sensor positioned above the shifting device. A distance between the shifting device and the load-monitoring sensor is less than or equal to about 10 m.
1. A downhole tool, comprising:
a shifting device;
a load-monitoring sensor positioned above the shifting device, wherein a distance between the shifting device and the load-monitoring sensor is less than or equal to about 10 m,
wherein the load-monitoring sensor is configured to measure an amount by which a load on the downhole tool changes in response to the shifting device contacting a restriction in a wellbore,
wherein the load comprises an axial tension load, an axial compression load, a rotational load, or a combination thereof; and
a body having a bore formed axially-therethrough and a recess formed in an outer surface thereof, wherein the load-monitoring sensor is positioned at least partially within the recess.
2. The downhole tool of claim 1 , wherein the restriction comprises a sleeve in the wellbore.
3. The downhole tool of claim 1 , wherein the restriction comprises a reduced cross-sectional area in the wellbore, a bend in the wellbore, or debris in the wellbore.
4. The downhole tool of claim 1 , further comprising a memory module positioned within the recess, wherein data representing the amount by which the load on the downhole tool increases or decreases is stored in the memory module.
5. The downhole tool of claim 1 , wherein the body is eccentric.
6. The downhole tool of claim 1 , further comprising:
a memory module positioned radially-inward from an inner surface of the body; and
a plurality of circumferentially-offset radial support members extending between the body and the memory module, wherein the axial bore is positioned circumferentially-between two of the radial support members.
7. The downhole tool of claim 1 , wherein the body is coupled to the shifting device.
8. The downhole tool of claim 1 , wherein the load-monitoring sensor comprises a strain gauge.
9. The downhole tool of claim 1 , wherein the load-monitoring sensor comprises a load cell.
10. The downhole tool of claim 1 , wherein the downhole tool is configured to be coupled to a drill string comprising a physical property sensor.
11. The downhole tool of claim 1 , wherein the physical property sensor measures at least one of pressure, temperature, and a wellbore trajectory.
12. A downhole tool, comprising:
a shifting device;
a first load-monitoring sensor positioned above the shifting device, wherein a first distance between the shifting device and the first load-monitoring sensor is less than or equal to about 10 m,
a second load monitoring sensor positioned above the shifting device, wherein a second distance between the shifting device and the second load-monitoring sensor is less than or equal to about 10 m,
wherein the first and second load-monitoring sensors are configured to measure an amount by which a load on the downhole tool changes in response to the shifting device contacting a restriction in a wellbore,
wherein the load comprises an axial tension load, an axial compression load, a rotational load, or a combination thereof; and
a body having a bore formed axially-therethough and first and second recesses formed in an outer surface thereof,
wherein the first load-monitoring sensor is positioned at least partially within the first recess, and
wherein the second load-monitoring sensor is positioned at least partially within the second recess.
13. The downhole tool of claim 12 , wherein the first recess is circumferentially-offset from the second recess.
14. The downhole tool of claim 12 , wherein the restriction comprises a sleeve in the wellbore.
15. The downhole tool of claim 12 , wherein the restriction comprises a reduced cross-sectional area in the wellbore, a bend in the wellbore, or debris in the wellbore.
16. The downhole tool of claim 12 , further comprising a memory module positioned within the body, wherein data representing the amount by which the load on the downhole tool increases or decreases is stored in the memory module.
17. The downhole tool of claim 12 , wherein the body is eccentric.
18. The downhole tool of claim 12 , wherein the body is coupled to the shifting device.
