SYSTEM AND METHOD TO DETECT A FLUID FLOW WITHOUT A TIPPING PULSE |
| 摘要 |
An apparatus and method to detect a fluid flow. The apparatus includes a nuclear magnetic resonance (NMR) tool to perform an NMR measurement on the fluid in a sensitive volume by establishing a magnetic field in the sensitive volume that exhibits a change in magnitude in a direction of the fluid flow when the fluid flow is radial with respect to the NMR tool and by transmitting refocus pulses, without any tipping pulse, to obtain the NMR measurement comprising spin echo signals. The system also includes a processor to receive the NMR measurement from the NMR tool and determine whether the fluid flow exists based on an amplitude of the NMR measurement. |

1. An apparatus to detect a fluid flow, the apparatus comprising:
a nuclear magnetic resonance (NMR) tool configured to perform an NMR measurement on the fluid in a sensitive volume by establishing a magnetic field in the sensitive volume that exhibits a change in magnitude in a direction of the fluid flow when the fluid flow is radial with respect to the NMR tool and by transmitting refocus pulses, without any tipping pulse, to obtain the NMR measurement comprising spin echo signals; and a processor configured to receive the NMR measurement from the NMR tool and determine whether the fluid flow exists based on an amplitude of the NMR measurement. |
