Title
(EN) Gamma ray section imaging device, and flow measurement device and method for multiphase flow
(ZH) 伽马射线截面成像装置、多相流流量测量装置及测量方法
Abstract
(EN)
The invention relates to a gamma ray section imaging device which is applied to a multiphase flow in an oil pipeline. The gamma ray section imaging device comprises at least two groups of probes, wherein each group of probes comprises a gamma ray detector array, a radiation source and a radiation source shielding device; the detector array is positioned at one side of the measured oil pipeline, and the normal of the detector array is axially vertical to the oil pipeline; the radiation source is positioned at the other side of the oil pipeline; the radiation source shielding device shields the radiation source; the gamma ray detector array included in each group of probes determines multiple detection intervals; each detection interval is determined by a detector in the gamma ray detector array and can obtain an average adsorption coefficient of the gamma ray; and thus, the average adsorption coefficients of different detection intervals are obtained at the same time and the instantaneous section image of the multiphase flow is obtained. The invention also relates to two oil-gas-water multiphase flow measurement devices and measurement methods thereof.
