摘要： The present disclosure provides a software-based approach for detecting bubbles in a fluid channel of a sensor system. According to this approach, readings from sensors which measure chemical characteristics of a sample fluid (e.g. ion concentrations of the sample fluid) are analysed. Any anomalous readings can be detected and analysed to determine whether the anomalous readings may be caused by the presence of one or more bubbles in the fluid channel. This approach removes the need to include additional conductivity sensors in the sensor system to detect bubbles, thereby freeing up sensor electrode sites which may be used for other sensors (e.g. additional calcium ion sensors). Bubbles that are detected can be shifted, or removed from the fluid channel entirely, by pumping fluid into the fluid channel.

摘要： Systems and methods for measuring multiphase flow of a fluid mixture in a downhole pipe of an oil/gas/water well are presented. According to one aspect, time-series measurement of the flow velocity and composition at a plurality of discrete azimuths of the pipe are measured. Measured time-correlated velocity and composition data are used to identify fluid components present in the pipe and estimate cross-sectional area and velocity of each of the fluid components. According to another aspect, pressure and temperature at the downhole pipe are measured, and used to calculate the mass density of each fluid component. For each of the fluid components, the cross-sectional area, velocity, and mass density are used to generate a corresponding mass flow rate. An algorithm with a set of parameters tuned to specific flow regimes is used to map the sensed data from the time-scrics measurements into the mass flow rate of each fluid component.
