Borehole ultrasonic flow meter |
摘要 |
A borehole tool incorporates an ultrasonic flow measuring device which enables calculation of the rate of flow of material through various perforated intervals of a well casing as a function of depth. Fluid flow rate is proportional to the difference in travel time of a pulse-type ultrasonic signal over a fixed distance in opposite directions through the fluid.
