Abstract: During the 14th Five-Year Plan period, China's logging technology has achieved leapfrog development in response to the exploration needs of complex oil and gas reservoirs such as deep and unconventional resources. Domestic high-end equipment has made breakthroughs in temperature and pressure resistance as well as multi-dimensional imaging, with core indicators reaching international advanced levels. Software platforms integrated with artificial intelligence and large model technologies have significantly improved the efficiency and accuracy of data processing and interpretation. Interpretation and evaluation technologies have enhanced the capability to assess complex reservoirs and remaining oil through a series of innovative methods. However, logging technology and equipment still face challenges such as reliability and adaptability in extreme environments, safety, and the deepened application of massive multi-source data. In the future, it is necessary to strengthen applied basic research, develop new sensors and intelligent electromechanical control technologies, and promote the comprehensive application of artificial intelligence to drive the continuous development of logging technology toward premium, intelligent, and environmentally friendly directions.
