DIAPIR STRUCTURES OF THE TEREK-SUNZHA OIL AND GAS REGION OF THE EASTERN CAUCASUS – QUASI-MUD VOLCANOES

abstract 1301706032 issue 130 pp. 421 – 446 30.06.2017 ru 1046
Within the Terek-Sunzha oil and gas region of the Eastern Caucasus a productive sediments are clearly expressed by the classical diapir due to the increase in power in the arched part of the strata of the Maikop clays. In accordance with the theory of I. M. Gubkin, developed based on the analysis of the structure of the oil and gas structures of mud volcanoes of Azerbaijan, diapirism of the structure is an important prerequisite for the formation of a mud volcano. The article provides a comparative analysis of diapir structures of the TerekSunzha oil and gas region of the Eastern Caucasus, which is quasi-mud unripe volcanoes, and structures of mud volcanoes in the South-Eastern end of the Caucasus range (the Apsheron Peninsula and other territories of Azerbaijan) and the North-Western end of the Caucasus range (the Kerch and Taman Peninsula). It is shown that the formation of diapir structure, when, in the context of high power clay strata, is not a sufficient condition for its transformation into a mud volcano. In such geological conditions, it is essential to determine the capacity of clay strata, but also the degree of its water-filled porosity, visco-plastic and fluid-forming properties, contributing to the transition of the breed in a phase of active current and the coming to the surface

THE ROLE OF SEISMICITY IN THE FORMATION OF GEOLOGICAL STRUCTURES WITHIN THE TEREK-SUNZHA PETROLEUM PROVINCE

abstract 1101506042 issue 110 pp. 633 – 652 30.06.2015 ru 1627
Within the Terek-Sunzha gas area we have identified patterns, most of which are divided into blocks in some cases with large amplitude shear. The processes of destruction of structures took place during the period of their formation and the subsequent time and due to the strong and catastrophic earthquakes. The article provides a statistical analysis of strong earthquakes in this region during the period 1688-2008 and the regularities of their existence. It is shown that the maximum number of earthquakes took place during the period of the depths of 5-12 km and the distribution of the number of strong earthquakes at levels subject to certain matematical patterns. With regard to the analysis of the distribution of earthquakes in a single year in the whole of the globe, we obtained the correlation of the displacement of rocks from levels of existence of earthquakes and possible displacement of rocks to very catastrophic earthquakes. We have also given the forecast frequency and the number of strong catastrophic earthquakes for the period from the beginning of the formation of structures up to the present time. We assessed maximum displacements of rock blocks during this time, which is in good agreement with the actual values of the displacement of rock blocks
