FREMGANGSMAATE FOR FORBEDRET SLAM PULS TELEMETRI. |
| 摘要 |
<p>For improved mud pulse telemetry, mud pulse signals generated by a downhole mud pulser 28 are detected at the surface by monitoring mud flow rate. Mud flow rate can be monitored by use of a flow meter 29 placed downstream from the surge suppressor 26. <IMAGE></p> |
