ANALYSIS OF ELECTRICAL LOGGING DATA INTERPRETATION IN THE STUDY OF LOW-RESERVOIR ROCKS FOR EXAMPLE MALODIVYTSKOHO DEPOSIT

Purpose. The subject matter of the research is low resistance reservoirs from which, based on the test results, flows of oil were received an example being terrigenous sediments in the Dnieper-Donets basin, namely, Malodivytske oil field. The goal of the research is to analyses electrical logging data interpretation in the low-reservoir investigation. Design/methodology/approach. The method of the research is collection, processing and interpretation of well survey research data with the help of the “Geopoisk” system. Complex electrical methods interpretation improves the accuracy and unambiguity of assessing resistance layers and penetration zones. Findings. Geologists are often faced with anomalous low resistivity, which lead to incorrect determination of the degree of saturation and oil-saturation capacity in determining the nature of saturation and composition reservoir fluids at well-logging in productive sediments. In determining the nature of well saturation, wells are interpreted as water-saturated under the geophysical wells research. However, the test gave many examples of low-resistance layers producing tides of anhydrous oil. Practical value/implications. We have analyzed electrical logging data interpretation in the productive reservoir and suggested a method to determine the nature of collectors saturation. We propose to use pulsed neutron-neutron logging method (PNNLM) to improve the efficiency of locating rocks, which can be collectors in low geological capacity section, and of determining the nature of saturation.
