Evaluation of Filtration Properties of Ore-bearing Rocks According to Electrical Logging Methods (Shu-Sarysu Uranium Province, Kazakhstan)

The issue of increasing the information content of logging methods in determining the filtration properties of uranium-containing rocks – sands in reservoir-infiltration deposits has been studied. To solve this problem, data from the apparent resistance method are traditionally used. Statistical calculations using the data of the apparent resistance method and the induction method are carried out in the work. When obtaining analytical links between the measured (electrical properties of sands) and applied (filtration coefficient) parameters, data from sands of representative granulometric composition were used; the representativeness of the sample of core materials used and data from electrical logging methods was ensured. The error in determining the values of the filtration property of sands according to calculation graphs / analytical expressions of logging-core is within acceptable limits for the industry.
