Research and analysis of domestic downhole localization based on biblimeasurement
To analyze the research status of downhole positioning through the bibliometric method and the knowledge graph generated by CiteSpace,and to clarify the research hotspot and development trend.Search the related research in the National Knowledge Infrastructure database(CNKI)from 1991-2022.The Excel was used to generate annual publication distribution,and the CiteSpace was used to generate knowledge maps of authors,institutions,keywords,etc.,and to analyze the research status and frontier of downhole positioning.There are 1164 effective documents,and the trend of publication increases first,then decreased and then stabilized.Cui Lizhen is the most published author(11),and the core author team,research team is mainly dominated by univer-sities,close cooperation and small cooperation;the technologies applied in downhole location are more and more extensive,but radio frequency(RF)identification technology and uWideband(uWB)technology are the main technologies of downhole positioning.Based on the research results,it is found that the technology applied to downhole positioning is gradually changing from RF identifi-cation to uWB,and it can be reasonably inferred that uWB technology in downhole positioning is still the next research hotspot.
