Abstract
A distributed flow properties wellbore measurement system. In a described embodiment, a system for determining at least one parameter of a fluid in a tubular string includes a pressure pulse generator attached to the tubular string and a set of sensors. The generator transmits a pressure pulse through the fluid. The set of sensors is used to determine a velocity of the pressure pulse transmitted through the fluid, and to determine a velocity of the pressure pulse reflected back through the fluid.

14. A method of determining at least one parameter of a fluid in a tubular string, the method comprising the steps of:
-
transmitting a pressure pulse through the fluid in the tubular string, thereby causing the pressure pulse to reflect back through the fluid;
determining a first velocity of the transmitted pressure pulse; and
determining a second velocity of the reflected pressure pulse. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92)
