摘要： An ultrasonic transceiver array provides for measurement and determination of flow rate of oil, water and gas in a multiphase flow in a pipe or conduit. The transceiver array is mounted externally and non-invasively in an elliptical arrangement on the pipe surface, resulting in an ellipsoid section of the flow cross-sectional area to be interrogated. The single ultrasonic transceiver array forms a tomographic image of multiphase flow to determine volume fraction of each phase; measure the total flow velocity to determine flow rate of individual phases and thus provide a three phase measurement capability. Both phase fractions and flow velocities can be determined at the same time, eliminating the need for two different systems to achieve that purpose.

摘要： Tomographic reconstruction is performed of cross-sectional images of downhole or surface multiphase flows containing water (brine), oil, and gas phases. Measures are obtained of digital transmission (or analog attenuation) and also of analog transit time to form two views of the same cross sectional flow in a location of interest in a flow conduit. The measures are then merged by synthesizing a composite image of the multiphase flows. Rather than performing a complex tomographic reconstruction requiring a large number of calculations, measures are also obtained directly from the tomographic pattern which can be used to reconstruct an approximation of the cross sectional flow by the superposition of circles of variable position, radius and density representing flow patterns.

摘要： A downhole salinity measurement and logging sensor system has multiple cells, each to measure conductivity, temperature and pressure of fluids at depths of interest in a wellbore. The multiple cells protect against effects of non-homogeneous wellbore fluids. The system also determines salinity of the liquid in the wellbore from conductance measurements, and stores the salinity data along with the temperature and pressure readings from the well. The sensors of conductivity, temperature and pressure are made using micro-fabrication technologies, and the system is packaged to comply with harsh downhole environments. The system may be deployed in the well with coiled tubing (CT), wireline or vehicles with a robotic system. The system can be deployed with an onboard memory, or with wireline surface access for real time access to measurement data or programming the device.
