Downhole data communication and logging system
View Patent ↗A logging system and method for use in a wellbore formed in an earth formation. A tubular conduit that extends from the surface into the wellbore is included in the system. The conduit includes a stabilizer with sensors to obtain data from the wellbore. A communication interface is used to communicate data from the stabilizer to the logging tool string. Also, a surface communication and control device, along with a telemetry device can be included in the system. The telemetry device could be used to send and receive data to and/or from the surface communication and control device, if needed. Also provided is a logging tool string that is capable of passing from a position within the conduit to a position outside the lower end of the conduit. In addition, a memory storage device used to and store data collected from the wellbore for further analysis and communication.
1. A logging system for use in a wellbore that comprises:
a conduit extending into the wellbore from the surface;
a movable logging tool string that is movable in relation to the conduit, the movable logging tool string having a first sensor, the movable logging tool string being capable of passing from a position within the conduit to a lower position extending outside a lower end of the conduit into the borehole;
a second sensor mechanically affixed to the conduit; and
a communication interface including:
a conduit communication device located in the conduit and communicatively coupled to the second sensor; and
a logging tool communication device located in the movable logging tool string;
wherein the conduit communication device is configured to provide wireless intra-device communication between the second sensor and the movable logging tool string.
2. The logging system of claim 1 , wherein the movable logging tool string is capable of being suspended in the position outside the conduit.
3. The logging system of claim 1 , further comprising a memory storage device coupled to the conduit capable of storing measurement data from the second sensor.
4. The logging system of claim 1 , further comprising a surface communication and control device located at the surface of the wellbore in communication with the movable logging tool string.
5. The logging system of claim 1 , wherein the second sensor is capable of communicating ultrasonic measurements.
6. The logging system of claim 1 , wherein the second sensor is capable of communicating micro resistivity measurements.
7. The logging system of claim 1 , wherein the second sensor is capable of communicating optical measurements.
8. The logging system of claim 1 , wherein the second sensor comprises a measurement electrode.
9. The logging system of claim 1 , comprising a stabilizer blade rigidly coupled to the conduit, wherein the stabilizer blade includes at least the second sensor.
10. The logging system of claim 1 , wherein the conduit is a drill string comprising a drill stabilizer.
11. The logging system of claim 1 , further comprising a memory storage device coupled to the logging tool string capable of storing measurement data from the first sensor.
12. A method for logging data from a wellbore that comprises:
lowering a conduit into the wellbore;
passing a movable logging tool string from the lower end of the conduit further into the wellbore, wherein the movable logging tool string comprises a first sensor;
inducing a second sensor mechanically affixed to the conduit to collect data from the wellbore or a formation;
wirelessly communicating the data collected by the second sensor intra-device from the second sensor to the movable logging tool string through a communication interface; and
storing the collected data from the second sensor within the movable logging tool string or communicating the collected data from the movable logging tool string to the surface, or both.
13. The method of claim 12 , further comprising collecting data from the movable logging tool string.
14. The method of claim 12 , further comprising storing the collected data from the second sensor.
15. The method of claim 12 , wherein the communication interface includes electronics to collect data from the second sensor.
16. The method of claim 15 , wherein the second sensor is capable of communicating ultrasonic measurements.
17. The method of claim 15 , wherein the second sensor is capable of communicating micro-resistivity measurements.
18. The method of claim 15 , wherein the second sensor is capable of communicating optical measurements.
19. The method of claim 15 , wherein the second sensor comprises a measurement electrode.
20. The method of claim 12 , comprising inducing a third sensor coupled to the conduit to collect data from the wellbore.
21. The method of claim 12 , further comprising drilling the wellbore.
22. The method of claim 12 , further comprising inducing the second sensor to collect data as the conduit is being removed from the wellbore.
23. The method of claim 12 , further comprising inducing the first sensor in the movable logging tool string to collect data from the wellbore or the formation.
