SY／T 6907-2012 标准规范下载简介
SY／T 6907-2012 伽马随钻测井仪简介：
"SY/T 6907-2012 伽马随钻测井仪"是中国石油行业标准，全称为"石油天然气工业测井仪器系列 伽马随钻测井仪"。这个标准主要规定了伽马随钻测井仪的设计、制造、试验、性能要求和验收方法等，以确保仪器在石油天然气勘探开发过程中的测量精度和可靠性。
伽马随钻测井仪是一种在钻井过程中实时测量井壁地层伽马射线强度的设备。它通过在钻杆中下放，可以提供详细的地层信息，如岩石类型、矿化程度、孔隙度和渗透率等，这对于地质评价、油藏描述、钻井导向以及事故预防都具有重要作用。
标准 SY/T 6907-2012 对伽马随钻测井仪的性能指标有明确要求，例如测量范围、精度、稳定性、抗干扰能力等，同时也规定了仪器的环境适应性，如温度、压力、湿度等，以确保其在各种恶劣井下环境下的正常工作。
总的来说，这个标准是伽马随钻测井仪在石油行业应用的技术依据，对保障石油钻井作业的质量和效率，提升石油资源的勘探开发水平具有重要意义。
