Abstract
The article presents a petrophysical justification for the use of the method of reflected electromagnetic waves – electromagnetic common depth point method (ECDP) – for studying cryohydrogeological conditions and solving other geological problems. An analysis of the results of the ECDP experimental work on the territory of an oil and gas field in the Republic of Sakha (Yakutia) in 2023 was carried out, including a study of the obtained distribution of the interval velocity of the electromagnetic signal with depth in a number of measurements. The result of data processing is presented in the form of a “virtual well” – a vertical distribution of specific electrical resistance with a resolution of 2-5 m in depth. The reliability of the results of the ECDP is confirmed by their stable correspondence with all measurements taken and geological information at depths of at least 500 m, in particular the nature of the occurrence of frozen rocks and the position of water-saturated rocks. The advantages of the ECDP are shown, such as: sensitivity of the studied parameter (electromagnetic signal velocity) to changes in the physical properties of rocks, increased detail and the non-requirement of a priori geological and geophysical information for quantitative interpretation of measurement data.
