摘　　要：一体化伽马探测器作为随钻伽马仪器核心部件已经被广泛使用,但受抗振结构、制作工艺等方面技术封锁,该产品一直被国外专业化制造公司垄断。随钻方位伽马成像测井仪器采用NaI(TI)闪烁探测器,基于闪烁晶体探测机制的理论分析,优化探测器抗振设计、创新设计探测器封装工艺,验证了探测器在低温、高温、振动条件下的稳定性。现场应用效果表明该产品主要性能指标达到国外同类产品水平,可以完全替代进口产品,满足现场施工要求。As the core module of the LWD gamma tools,the integrated gamma detector has been widely used.However,due to the technical blockade of anti-vibration structure and manufacturing technology,the product has been monopolized by foreign specialized manufacturing companies.The azimuthal gamma imaging logging tool while drilling uses NaI(TI)scintillation detectors.Based on the theoretical analysis of the scintillation crystal detection mechanism,the anti-vibration design of the detector is optimized,and packaging process of the detector is innovatively designed.The stability of the detector under low temperature,high temperature and vibration conditions is verified.The field application effect shows that the main performance indicators of this product reach the level of similar foreign products,which can completely replace imported products and meet the requirements of on-site construction.
