Well logging evaluation and characterization of geological information for deep and ultra-deep drilling wells
In accordance with the strategic deployment of deep-sea,deep-earth,deep-space and deep-blue initiatives,land drilling is continuously entering towards deep and ultra-deep reservoirs.How-ever,the collection of advanced well log series are limited for the deep and ultra-deep strata,and will re-sult in interpretation ambiguity of well log data.Therefore,it is urgent to use the limited geophysical log-ging information to fully interpret on the geological information contained in deep and ultra-deep drilling.This paper firstly discusses the focus of logging evaluation in deep and ultra-deep reservoirs based on exten-sive literature retrieval.Through the analysis of typical research cases,it systematically reviews the appli-cation of logging geology in deep and ultra-deep fields,including using logging data to interpret structural geological phenomena,pick up sedimentary information,evaluate and predict reservoir characteristics,and evaluate in-situ stress using logging data.Finally,the development trend of deep and ultra-deep fields is discussed:paying attention to the integration of multi-data source(such as core,experimental data,and seismic data),and developing advanced rock physical models that adapt to the environmental factors of deep and ultra-deep environments based on their differences.At the same time,in the context of the de-velopment of big data and artificial intelligence,the advantages of new technology logging are utilized to promote breakthroughs in the field of logging geology in deep and ultra-deep fields,thus breaking through technical bottlenecks.
