Abstract
In the Mesozoic deposits of the study area, formation waters are complex solutions saturated with various mineral salts, microcomponents and rare elements. Studying formation water samples from near-contact zones for the content of rare and trace elements makes it possible to trace changes in their concentration depending on the position of the sampled interval relative to the water-hydrocarbon contact, in plan and along the section. To jointly take into account the remoteness of the studied object from the deposit along the section and by area, the work uses graphs of spatial changes in the contents of rare elements relative to the position of the hydrocarbon deposit.
Based on the conducted research, it was established that in the distribution of microcomponents and rare elements in the reservoir-water-rock system, in the hydrochemical environment of displaced phase equilibrium for most microelements, a connection is manifested between their increased concentrations and hydrocarbon accumulations. The main manifestations of interaction are geochemical processes of distribution of reservoir components and the rocks enclosing them, into the surrounding groundwater. As a result of such mass transfer, water areoles of microelement dispersion are formed around the oil and gas reservoir. Such phenomena have been established in a number of structures and deposits in the region, especially in the formation waters of the Jurassic aquifer complex.
