Abstract

The operation of a gamma densitometer (GD) of ID = 100 mm is considered; it is intended for the diagnostics of three-phase oil–water–gas flows using the separationless method, when the composition of components is determined by a spectrometric analysis of gamma irradiation with two different photon energies. The ²⁴¹Am and ¹³⁷Cs isotopes, installed in the same housing, are used as gamma sources, while a gamma detector is made on the basis of the BGO crystal of 40 mm in diameter and height. Information about the design, measuring electronics, and main characteristics of the GD is given. The method used for the temperature stabilization of the recorded radiation intensities for both isotopes within a range of ambient temperature from 10 to 35^oC is presented.

双同位素光谱伽马密度计，用于三相油水煤气流的诊断

摘要

考虑使用ID = 100 mm的伽马密度计（GD）的操作；当通过两种不同光子能量的γ辐射的光谱分析确定组分的组成时，它适用于使用无分离方法的三相油气水流诊断。安装在同一外壳中的²⁴¹ Am和¹³⁷ Cs同位素用作伽马射线源，而伽马射线探测器是根据直径和高度为40 mm的BGO晶体制成的。给出了有关GD的设计，测量电子设备和主要特性的信息。提出了一种用于在环境温度10到35 ^o C范围内稳定两种同位素记录的辐射强度的方法。
