    • Abstract
  • Imaging log has been used widely used due to its high resolution and abundant information capacity.Nevertheless,the difficulties may arise from the resolution matching in data processing with the conventional logging data,because of high sampling density of imaging log.Traditional interpolation method can not resolve this problem.Conventional logging GR(gamma ray) curve is interpolated by using the Akima interpolation method with high efficiency and precision,and then,the depth displacement of image logging GR curve is calculated by using correlation analysis.The method developed in the present study has the advantages of fast resolution matching and depth correction,and will better improve the image interpretation of image logging.
