A design of natural gamma spectrum logging system

The paper presents a new design scheme of natural gamma spectrum logging system. The system consists of two independent subsystems, including the acquisition system and the transmission system connected by CAN bus for communication, which facilitates the scalability of the data acquisition system. The probe of neutron, density and sound wave will be implemented during one well logging exploration. TCP/IP protocol is applied between the transmission system and surface system. The long-haul high-speed fiber-optic communications will guarantee the reliability of the design.
