Abstract: Nanxiang basin is one of the earliest basins to carry out the shale oil and gas exploration.Logging technology plays an important role in the traditional oil and gas exploration,and shale oil and gas exploration technology is also indispensable.Through the application analysis of logging technology in shale oil and gas exploration,the logging technology shortcomings have been analyzed in detail.On the basis of development status analysis of unconventional oil and gas logging technology home and abroad,unconventional logging technology will follow the quantified,downhole and realtime direction.Great emphasis should be placed on information processing so as to realize all-round service of before,during and after drilling,before and after pressure,to carry out quantitative logging and remote geosteering,and realize the appreciation and interests maximization of logging.
