摘要 |
<p>WELL-LOGGING TOOL A well-logging tool, for use within a well borehole having a flowing fluid therein, has a selective bypass means for directing a portion of the flowing fluid away from the housing of the well-logging tool upon the flowing fluid exerting a predetermined pressure force upon a packer, whereby damage to the packer from increased pressure forces is minimized and flow characteristics of a fluid flowing at widely varying flow rates may be measured.</p> |
