Geophysical Logging Parameter Characteristics and Spontaneous Potential Correction for Sandstone Type Uranium Deposits in the Northeastern of Ordos Basin
Northeastern Ordos Basin is the main production area of in-situ leaching sandstone type uranium deposits.In order to better conduct geophysical interpretation,the physical property parameter data in the research area were collected in statistics to study their curve characteristics and logging response to rock types which laying a good foundation of lithology identification and layer division.Based on the influencing factors of spontaneous potential,response to situations such as significant drift of spontaneous potential curve,software was used to correct the baseline of spontaneous potential and filter out interference,which effectively improved the drift phenomenon,and narrowed the range of curve value variation,and the corrected data basically conforms to the measurement law of spontaneous potential.This research is helpful for the geological application of spontaneous potential curves and has a positive guiding role in mineral exploration work.
