Embodiment Construction
[0047] The present invention will be further described below in conjunction with the embodiments and drawings.
[0048] A method for measuring the phase fraction of a multiphase flow with a single source ray, which is characterized in that the following steps are performed:
[0049] Step 1. Make the high-energy single-source γ-rays be directed to the scattering material and the metal target at the same time; the scattering material performs Compton scattering on the high-energy single-source γ-ray to obtain low-energy γ-rays; the metal target is subjected to the high-energy single-source γ X-rays are emitted by the ray bombardment, and the scattering material and the metal target can be set in the source bin assembly;
[0050] Step two, collimate the low-energy γ-ray and X-ray, and then make them shoot toward the venturi along the same diameter direction of the venturi. The multiphase flow of oil, gas and water flows in the venturi, and inside the venturi A multiphase fluid channel ...
