由石油大学(华东)研制的岩芯伽马测量仪现已问世,并通过了中国石油天然气总公司组织的技术鉴定。 该仪器是在美国岩芯公司生产的同类仪器基础上,被改进研制的一台用微机控制和处理的仪器。它从信号采集到绘图实现了微机数字化控制和处理,采用了高精度浮点计算和数字滤波,消除了美国仪器使用模拟器带来的漂移问题;提高了测量精度(优于0.5%);对统计 The core gamma meter developed by the University of Petroleum (East China) has now come out and passed the technical appraisal organized by China National Petroleum Corporation. The instrument was developed on the basis of the same type of instruments manufactured by the American Core Company using a microcomputer controlled and processed instrument. It digitally controls and processes the microcomputer from signal acquisition to plotting. It uses high-precision floating-point calculations and digital filtering to eliminate drift problems caused by the use of simulators in the United States; to improve the measurement accuracy (better than 0.5%); statistics
