Keywords: polymer potassium chloride drilling fluids, electrical resistivity, saturation pattern
Annotation:
The article examines the effect of polymer potassium chloride drilling fluids on the results of measurements of electrical resistance in wells, identifies the reasons for the unreliability of the results obtained and the ambiguity of determining the specific electrical resistance of the reservoir. The approaches to correction of induction logging curves by comparison with reference media are substantiated. The use of multi-probe lateral logging to assess the saturation pattern is proposed. Laboratory core studies were carried out for different types of solutions (KCl and NaCl), which showed an underestimation of the determined electrical resistivity and a decrease in the oil saturation coefficient. The use of multi-probe thermal logging in combination with gas logging or nuclear magnetic logging is recommended as an optimal GIS complex.
