摘要
研制的核磁共振录井仪测试系统主要由微机、主控电路、输出功率放大器、输入前置放大器、磁体和探头等部分构成。它具有结构紧凑、频率可调、低磁场、自动计算石油参数、PC机控制等技术特点,可实现岩心、岩屑及井壁取心样的孔隙度、渗透率、饱和度及可动流体等重要储层物性参数的钻井现场快速检测。现场应用表明,该仪器录井结果很好,测试结果与解释结果符合率达到100%,具有很好的社会效益和经济效益。
The portable NMR logging analyzer is mainly used to quickly and precisely determine the petrophysical parameters of core, cuttings and side-wall core at well site. The structure and principle, technological target, technological feature of the logging analyzer are discussed. The analyzer has been applied in the Jilin Oilfield, and the result indicates that it is reliable.
