Wide field neutron-gamma spectrum logging is a kind of pulsed neutron logging technology. Firstly, record the total gam-ma ray spectrum of capture gamma ray caused by the interaction between neutron and formation and natural gamma radioactivity, and then parse spectrum to obtain formation element content and formation density and calculate remaining oil saturation. In this ar-ticle, wide energy field neutron-gamma spectrum logging principle and interpretation methods were proposed. Combined with ex-amples, this technology was considered to have unique advantages in determining the reservoir skeleton of sand-shale profile and the aspects of mineral composition, contents, reservoir properties and remaining oil saturation of mud.
