PETROMAGNETIC PROPERTIES OF SOILS WITHIN KHLEBNOVSKY OIL FIELD (SARATOV REGION) AND THEIR INTERPRETATIVE SIGNIFICANCE
Abstract
Petromagnetic properties of soils were studied in the territory of Khlebnovsky oil field (Saratov region, Russian Federation). Magnetic susceptibility was measured at low (?lf) and high (?hf) frequencies in soils before and after heating up to 500°C including the frequency dependence of magnetic susceptibility (?fd) and the thermomagnetic coefficient (d?). It was observed that in the studied soils, ?lf varied from 3.05?10-7 m3/kg to 1.56?10-6 m3/kg with an average value of 5.54?10-7 m3/kg; ?hf - from 2.84?10-7 m3 / kg to 1.49?10-6 m3/kg with an average value of 5.21?10-7 m3/kg; ?fd - from 4.13 % to 7.22 % with an average value of 6.21 % and d?- from 0.65 to 21.8 with an average value of 4.4. The thermomagnetic effect (d?) varied from 0.65 to 21.8 with an average value of 4.4. An extensive anomalous zone with thermomagnetic effect values of more than 3 units was formed in the studied territory (we took this as the minimum anomalous value). The zone of anomalous values of thermomagnetic effect in the soils within the Khlebnovsky oil field formed a single area of anomaly in the Northern and Central parts. Anomalies were documented in 26 sample test points. Most of the anomalies were observed in thermomagnetic effect values ranging from 3 to 10 units, and in the Western part of the anomalous zone, a core was formed with values from 10 units and higher. In the center of the core, the maximum value of thermomagnetic effect was 21.8 units. It is possible that both identified anomalies formed a single ring anomaly around the Khlebnovsky oil field, but to confirm this assumption, it is necessary to conduct a more detailed petromagnetic testing of the studied territory. As shown by this research, thermomagnetic coefficient d? was observed to be the most significant of all the measured petromagnetic parameters when detecting accumulations of hydrocarbon deposits.
