To improve the oil and gas exploration accuracy and engineering safety guarantee capability under deep and ultra-deep complex geological conditions in Bohai Oilfield,and to meet the technical challenges such as deep reservoir burial depth,high temperature and high pressure,low drilling rate in hard rock formation,and frequent downhole complex situations,the methods of literature analysis,industrial case verification and technical efficiency evaluation were used.This paper systematically studies the correlation mechanism between the logging parameters monitored on the ground and the response of downhole geology-engineering information,analyzes the iterative path of the technical chain of logging data acquisition-processing-interpretation,and evaluates the technical effectiveness of the five application dimensions of reservoir evaluation,fluid identification,geosteering,intelligent monitoring and remote decision-making.The research results show that:①The comprehensive mud logging system can be connected with up to 228 sensors of various types,the data acquisition frequency can reach up to 100 Hz,the gas fast chromatographic detection and analysis cycle can be compressed to within 30 s,and the sensitivity of hydrocarbon group analysis can reach 1 mg/L;②Continuously deepen the application of logging data in geological and drilling engineering,greatly improve the efficiency of reservoir evaluation and hydrocarbon reservoir interpretation,the accuracy of lithology identification is 96.2%,the speed of hydrocarbon reservoir identification is shortened from 30 min to 5 min,realize early warning of lost circulation and well kick,advance the abnormal prediction by 3-5 min,and reduce 20%of non-production time;③Continuously promote the digital transformation and cross-professional data fusion of the mud logging industry,and realize the intelligent service upgrade in exploration research and drilling operations,which has become an important direction for the high-quality development of the mud logging industry.Conclusions demonstrate that mud logging technology plays a critical role in deep-layer hydrocarbon exploration at Bohai Oilfield.Collaborative innovation involving downhole real-time sensors,near-wellhead analysis systems,and intelligent decision-making platforms provides theoretical and practical guidance for:technological breakthroughs in data acquisition for deeplayer exploration,development of next-generation mud logging equipment and advancement of the mud logging industry.
