FLUID SKIN FRICTION SENSING DEVICE AND METHOD |
摘要 |
The apparatus includes a signal sensing demodulator device and a skin fricti on sensing device positionable within the wellbore. Both devices are in informational communication with each other. The method includes exposing th e skin friction sensing device to a fluid flow, transmitting a signal obtained as a result of a movement of the skin friction sensing device from the fluid flow to a signal sensing demodulator device, converting the signal to a numerical value, and computing a parameter or parameters of the fluid flow i n the wellbore from the numerical value.
