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. Specifically, China’s 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 have integrated with artificial intelligence and large model technologies, significantly improving 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, current logging technology and equipment still face challenges in terms of reliability and adaptability in extreme environments, safety, and further application of massive multi-source data, etc. In the future, it is necessary to strengthen applied and basic research, develop new sensors and intelligent electromechanical control technologies, and promote the comprehensive application of artificial intelligence, so as to drive the continuous development of logging technology toward premium, intelligent, and environmentally friendly directions.
