TOP DRIVE WITH TOP ENTRY AND LINE INSERTED THERETHROUGH FOR DATA GATHERING THROUGH THE DRILL STRING |
| 摘要 |
A method for transmitting data from a downhole instrument to a surface location includes running the downhole instrument into a wellbore on a line. The downhole instrument and at least a portion of the line are positioned inside a drill string. The downhole instrument includes first and second sets of fingers that contact an inner surface of the drill string. The downhole instrument measures an effect occurring in the drill string. The effect is due to perturbations in the drill string during a drilling process. |

1. A method for transmitting data from a downhole instrument to a surface location, comprising:
running the downhole instrument into a wellbore on a line, wherein the downhole instrument and at least a portion of the line are positioned inside a drill string, and wherein the downhole instrument comprises:
a first set of fingers configured to contact an inner surface of the drill string; anda second set fingers configured to contact the inner surface of the drill string; and measuring an effect occurring in the drill string using the downhole instrument, wherein the effect is due to perturbations in the drill string during a drilling process. |
