西安石油勘探仪器总厂研制的FCS801超深井闪烁放射性测井仪改进面板于1986年11月6日在该厂正式通过总厂技术审定。会议对改进面板的性能指标和各项资料进行了审议,一致认为改进面板不仅达到而且超过了原面板的技术要求,并对顺利通过现场测井试验取得较好评价,给予了肯定。 FCS801超深井闪烁放射性测井仪面板是在综合了各种闪烁放射性测井面板优点的基础上试制成功的。因此它除了具备其它面板的一些优点外,尚具有线性范围宽,在0～3.2千赫范围内,非线性误差均小于±3％;输出电流大,输入800赫本机校频信号时,输出电流在接300欧姆负载情况下,大于300微安。
Xi’an Petroleum Exploration Instrument Factory developed FCS801 ultra-deep well scintillometer to improve the panel on November 6, 1986 at the plant officially passed the technical approval of the plant. The meeting reviewed the performance index and various data of the improved panel and agreed that the improved panel not only met but also exceeded the technical requirements of the original panel and affirmed the successful evaluation of the field through well logging test. The FCS801 Ultra-Deep Well Scintillation Radioactivity Logging Panel was trial-manufactured on the basis of the merits of the various scintillation radioactive logging panels. So it has some other advantages in addition to the panel, but also has a wide linear range, in the range of 0 to 3.2 kHz, the nonlinear error is less than ± 3%; output current, input 800 Hz local frequency signal, the output current In the case of 300 ohm load, greater than 300 microamps.
