Advances in The Geologic Applications of Electrical Imaging Logging Technology

The advances in geologic applications of electrical imaging logging technology at home and abroad are summarized through surveying over 170 articles.Initially,this technology is mainly applied to the researches of sedimentation,reservoir and side borehole structure.As the technical development,applications of electrical imaging logging data in geology are becoming much wider and deeper.Their applications to sedimentary facies show a tendency to the researches on vertical facies sequence,comprehensive interpretation and maping.Many results have been achieved from the study of thin-bedded reservoirs,reservoir heterogeneity and physical properties,particularly in fracture system with the most researches and achievements.Electrical imaging logging technology has been attempted to apply to oil-based mud imaging logging,whose measured data are then used for stratigraphic division and fault identification.And also electrical imaging logging data are tried to be used to identify high water zone.Nowdays,geologic applications of electrical imaging logging data are only limited to single well,while less emphasis and research on the integrated application of numerical electrical imaging well logging data.Therefore,integrated researches on numerical electrical imaging well logging data play an important role in both theory and application.
