| 摘 要： | 和其它核磁仪器相比,核磁共振测井仪器的环境更为复杂和苛刻,诸如测井速度,井下仪器的存储容量以及功耗诱发的计算速度等限制与测量数据量成正比的检测性能之间形成了矛盾,并最终反映到了对井下仪器数据采集系统实时性的要求上.实现了一种数字相敏检波处理算法的优化方法,有效解决了各种限制与实时性之间的矛盾,通过工程验证,完全满足核磁共振测井仪数据采集处理系统计算实时性、功耗等要求.

| Abstract: | In comparison with other NMR instruments,the environment of NMR logging instrument is much more rigorous and complex.Many restrictions such as logging speed,storage capacity of underground instrument and the calculation speed induced by the power consumption,are in contradiction with detection performance which is directly proportional to the amount of measuring data.And the contradiction finally reflects in the requirements for the real-time of underground instruments data acquisition system.To achieve the... |
