The results of experimental studies of the effect of the magnetic field of the well casing on the operation of the gas-filled neutron tube used in the logging equipment are reported. The operation of the ion source was evaluated in terms of the parameters of the pulsed currents of charged particles recorded at the target of the neutron tube. Analysis shows that a longitudinal magnetic field, as compared with a transverse magnetic field, has a greater influence on the performance of the tube. Of the screening methods studied the one with a robust magnetic-steel housing for the equipment turned out to be most effective.

井场磁场对地球物理仪器中子管影响的研究

报道了井套管磁场对测井设备所用充气中子管运行影响的实验研究结果。根据记录在中子管目标处的带电粒子的脉冲电流参数来评估离子源的操作。分析表明,与横向磁场相比,纵向磁场对管子的性能影响更大。在研究的筛选方法中,为设备配备了坚固的磁钢外壳的筛选方法被证明是最有效的。
