摘要
介绍一种连续测量岩芯γ射线强度的仪器,仪器采用Φ50×50NaI(Tl)晶体探测器、大功率电源转换电路和大电流的驱动电路,具有测量精度高,性能稳定等优点。其测得的岩芯γ射线强度曲线为油气勘探中的岩性对比、岩芯归位等提供重要的依据。经初步实验,达到了预期的效果。
Introduction of a continuous measurement of core g-ray intensity of the instrument,it has high accuracy,stable performance,becausing of Φ50 × 50 NaI（Tl） crystal detector,high-power high-current power conversion circuit and drive circuit.The measured g-ray intensity curve of core oil and gas exploration in the lithologic contrast,core homing provide an important basis for such.After preliminary experiments,achieved the expected results.
