    摘要: Methods and systems are described that provide for measuring flow properties of multiphase mixtures within a pipe carry gas-liquid hydrocarbons and water produced from oil-gas wells. The methods and systems may provide for a combination of a clamp-on ultrasonic gas flow meter to measure flow characteristics of a gas phase in a pipeline and a pulsed ultrasonic Doppler sensor(s) and/or an RF/microwave electromagnetic sensor(s) to measure flow characteristics of a liquid phase. The combination of sensors may provide for multiphase flow measurements under certain flow conditions, such as when the gas-liquid is flowing in a substantially horizontal pipeline, when the flow is stratified or is caused to be stratified and/or the like.

    摘要: An immersion probe is described that includes sensing elements that allow for hydrate inhibitor dosage to be more efficiently provided into gas and/or oil wells. The immersion probe allows for detection of first appearance of water in a multiphase flow in a well, measuring the amount of inhibitor in water within the well, determining an accurate water-cut, and measuring other property such as water salinity. Accordingly, with the known water-cut, salinity and the water flow rate inferred from the inhibitor injection flow rate and inhibitor-in-water fraction, a correct dosage of the inhibitor can be injected to the well in order to prevent hydrate formation, while reducing overdosing. Water flow rate may also be inferred from an independently measured liquid flow rate and the immersion-probe measured water cut.

    摘要: A system and method for determining characteristics of a multiphase flow in a well/pipe are disclosed. The disclosed system and method use an optical immersion probe including a flow gap across which two or more types of radiation are transmitted in order to measure absorptions of two or more substances within the multiphase flow. Primarily, broadband ultraviolet (UV) and/or near infrared radiations (NIR) are utilized with the probe to gather absorption data at and/or around at least one of the water peaks and at and/or around one or more oil or oil-condensate peaks. This data may be utilized to calculate the water-cut of the multiphase flow over a wider range of gas volume fractions. Additionally, pressure ports having pressure sensors being located on the optical immersion probe for determining the impact pressures and flow rates of different phases of the multiphase flow may also be used.
