| Abstract: | Based on the multi-channel natural Gamma-ray logging are introduced.In order to meet the oil well logging large volume of data acquisition systems and high-speed data transmission needs,development of a new Gamma-ray logging.The instrument used 12 high-speed ADC completed nuclear pulse to quantify the extent of figures,by the CPLD complete spectrum of computing and SRAM controller as a complete collection of data stored in the dual-port RAM.CAN bus used for data communications,data collection and data storage upload parallel working.Proved that the system as a whole has a high reliability and real-time. |
