METHOD AND APPARATUS FOR DETERMINING A LEVEL OF A FLUID IN COMMUNICATION WITH A DOWNHOLE PUMP |
摘要 |
<p>A method and apparatus for determining a level of a fluid in communication with a downhole pump during a pumping operation is disclosed. The method involves receiving a signal representing pump vibrations generated by operation of the pump during the pumping operation, and based on the signal, generating a vibration value characterizing the pump vibrations. The method also involves using a correlation between pump vibrations and fluid level to generate a fluid level value corresponding to the vibration value.</p> |
