摘要： A system and method for estimating a fluid loss in a borehole while drilling are disclosed. A drill string disposed in the borehole. A first sensor of the drill string is configured to obtain a first fluid parameter measurement at a first location along the drill string. A second sensor of the drill string is configured to obtain a second fluid parameter measurement at a second location axially separated from the first location. A processor estimates a fluid loss along the drill string using the first fluid parameter measurement and the second fluid parameter measurement performs an action in response to the estimated fluid loss.
