MONITORING OF TECHNOGENIC SEISMIC IMPACT IN ORE MINING

(Golik V.I. Komashchenko V.I. Lyashenko V.I. )

Relevance of work is caused by importance of a problem of decrease in dangerous influence of technogenic seismicity by underground mining of rocky fields with use of explosive works. Generalization is executed and results of the analysis of the theory and practice of an explosive otboyka of metal ores are given. Methods of management of a condition of the massif with use of opportunities of miner geophysics are concretized. Recommendations about restriction of negative influence of technogenic seismicity are made.......

FEASIBILITY STUDY OF APPLICATION OF ELECTROMAGNETIC GEOTHERMOMETER FOR HYDROCARBON PROSPECTING

(Spichak V.V. Zakharova O.K. )

Feasibility study is carried out aimed at finding temperature anomalies typical for hydrocarbon deposits of organic origin. The temperature forecast in depth below borehole bottom is carried out by electromagnetic geothermometer using the electromagnetic sounding data in the vicinity of boreholes and available geotherms. By the example of the electromagnetic and temperature data originated from the oil-bearing area of Soultz-sous-Forets (France) it is indicated that accuracy of the temperature forecast by means of electromagnetic geothermometer (carried out both after drilling and in its step-by-step process) is sufficient for detecting even negligible temperature anomalies (1-2%), caused by generation of hydrocarbons of organic nature.......

PALEOZOIC COMPLEX OF SEDIMENTARY BASINS WEST OF THE TURAN PLATE AND THE TERRITORY TO THE EAST OF THE URAL FOLDED SYSTEM

(Azhgaliev D.K. Kurmetov B.K. Nursultanova S.N. Nurpeisov E.T. Taskinbayev K.M. )

According to the results of the Project Comprehensive Study of the Sedimentation Basins of Kazakhstan was substantiated the high prospect of Paleozoic deposits in the west of the Turan Plate (Ustyurt-Bozashi and Mangyshlak). Also were obtained new data on the nature of the occurrence of the Paleozoic stratum in the context of all basins located on the east of Ural folded systemAkchulakovand etc.; 2009-2013). These pools are part of various structures of the first order. A high assessment of the prospects and the forecast potential of sedimentary basinsis shown, obtained as a result of the study and attraction of the Paleozoic sequence as the most important area of research. Almost all of the basins, including the Caspian Sea, Paleozoic complex is the main direction of exploration. Accordingly, the need to increase the depth of exploration is one of the main results of the Project, which is a condition for an objective assessment of the prospects and potential of the territories. It is noted that there are favorable conditions for the substantiation of the priority objects in the Paleozoic, taking into account the already established fund of structures. The study of large depths in this case makes it possible to count on wide opportunities for forecasting and discovering new large deposits occurring in more complex geological conditions. It should be assumed that large deposits are associated with objects of the unconventional types - non-anticlinal type. Due to the lack of data the position of the Paleozoic roof in Ustyurt-Bozashi and Mangyshlak was ambiguous; In the section of the Uzen-Karamandybas-Tenge zone were obtained high dynamic characteristics, was made a forecast in the Paleozoic strata of the stratification and in the large and prospective search elevations. The regularities of petroleum potential established in the west of the Turan Plate provide certain material and opportunities for conducting regional and area studies in the south-eastern basins in order to preliminarily assess the full-fledged identification of the Paleozoic sequence and justify its perspectivity. The degree of study of the Paleozoic strata of sedimentary basins in the south-east is at the initial stage of study. The Aral, South Torgai and Zaisan basins stand out more “characteristic”. They have the prerequisites for the selection of search objects and the detection of new clusters of hydrocarbons. The study of the Paleozoic strata in the large territory under consideration makes it possible to substantiate a regional model for its formation and tracking, to clarify the deep structure of sedimentary basins for solving a number of issues of fundamental importance.......

SEISMOGRAVITATIONAL PROCESSES AND GRAVITOMAGNETIC DISTURBANCES ACCOMPANYING GEO-PHYSICAL CATASTROPHES

(Sobisevich L.E. )

The observational data suggesting that both at the stage of preparation of the seismic event, when rock formations are rear-ranged in the forthcoming focal structures, and during the progress of the main event, large-scale reformation of individual blocks in the focal area may be responsible for the excitation of seismogravitational and gravitomagnetic disturbances are presented. Mentioned disturbances tend to be observed in various geophysical fields [Linkov et al., 1982-1996; Sobisevich et al., 2019]. Results of analysis of seismotectonic and gravitational processes obtained on the basis of the Geophysical Observatory in Northern Caucasus are discussed.......
