X-RAY-FLUORESCENCE ANALYZER OF GAS-FLUID FLOW COMPONENT COMPOSITION AND COMPONENT-BY-COMPONENT FLOW RATE IN OIL WELLS Russian patent published in 2010 - IPC G01N23/223 

FIELD: instrument making.

SUBSTANCE: proposed analyzer is used to determine component composition and rate parameters of three-component flow. Proposed invention consists in that the analyzer incorporates X-ray tube, primary and secondary collimators, roentgen-transparent inserts arranged in the walls of pipe carrying controlled gas-fluid flow, as well as multiple X-ray radiation detectors arranged in various directions relative to aforesaid pipe. Note that proposed device incorporates secondary radiators arranged in secondary collimator holes, gas-fluid flow pressure and temperature pickups, discriminator, flow conditions controller, X-ray tube controller, timers, jet straightening device and flow normalizer, and electronic unit.

EFFECT: higher accuracy.
