In this article, based on the data on the convective heat transfer from the mantle wedge to the 2D heat flow anomaly observed in the rear of the Central Crimean arch, the angle of inclination of the mantle wedge and the rate of subduction of the East Black Sea lithospheric plate under the lithosphere of the Scythian continental plate (Crimean region) are estimated. The effects of the 410 km and 660 km phase transitions are taken into account. Within the framework of the geodynamic model constructed the horizontal extent of the 2D heat flux anomaly observed in the rear of the Crimea mountain belt corresponds to subduction velocity of ~ 40 mm per year which is close to that observed with the help of geodetic means. Ascending convective movements in the mantle can carry mantle calcareous-alkaline magmas (with hydrocarbon geo-fluids contained in them) into the near-surface layers of the Earth’s crust, and, consequently, oil and gas fields should be confined to zones located in the upper part of the lithosphere, above the convective vortices of the Karig.

X-ray structural studies have shown that with the increase of the life of the pipes, the surface layers of the metal adsorb a significant amount of gases (hydrogen, oxygen and sulfur), especially this is strongly manifested in the field of corrosion defects (ulcers, pitting). Also, it was found that in the process of long-term operation, the metal of the pipe walls is heavily flooded, which directly leads to its brittle and, as a consequence, increased hardness and reduced ductility. Such studies are unique in the subject of corrosion-mechanical resistance of metal and its degradation during long-term operation in the presence of alternating loads and at the same time, the aggressive environments of oil and gas fields.

The paper shows that in the oil deposits formed in the Earth crust, due to the overpressure hydrocarbon components migration to the sedimentary cover and penetration to the field occur. As a result of vertical hydrocarbon migration in the oil and gas fields, a subvertical zone differing by its physical properties from the environment is formed. Such a subvertical zone affects geophysical, geochemical and logging data as well. Therefore, while migrate to the near-surface zone, hydrocarbons interact with a complex of rocks of sedimentary cover. As a result of impacting of fines forming hydrocarbons with the complex of subsurface rocks, a part of hydrocarbon flow energy transforms into the fluctuations of minor particles of subsurface rocks, and the other one, in the result of atoms and molecules impact - into the irregular molecule motion. A part of mechanical energy of moving particles transforms into another - thermal type of energy, as a result of which the environment gets “warmed”. Herewith, the temperature in near-surface zones differs from environment. Therefore, in the oil and gas fields in subvertical zones a heterogeneous area differing from the environment by geophysical, geochemical and other characteristics is formed. Based on the research data carried out by numerous specialists, it was justified that the changing of geophysical parameters is affected not only by oil-gas field, but near-surface zone as well. This feature is recommended to consider in the analysis of geophysical data.
