Abstract: NetLog is China’s first independently-developed logging IOT system, which connects oil and gas wells, logging equipment, processing platforms, professionals and oilfield application systems of different geographic locations by means of wideband satellite, wireless digital dedicated network, and 3G and 4G communications network. It can provide automatic data acquisition in the full logging process and online processing and remote control to coordinate the work of onsite logging equipment, base interpretation systems and remote technological experts, helping production managers make decisions in time and find and identify oil and gas intervals rapidly and accurately. The system is composed of three parts - site acquisition and transmission subsystem, base data processing and analysis center, and integrated application platform. The system is designed to have a transmission capacity of 50,000 well/times per year on average. It can satisfy the demand of 200 wells at the same time with real-time transmission. It can be connected to the domestic and foreign high-end logging equipment to complete conventional logging and special imaging logging services as well as other variety of logging services. Widely used in many domestic oil fields, the system optimizes logging service process, improves accuracy of data interpretation and logging efficiency and lowers the risks for exploration and development.
