Drilling Technology

In the article, we analyze types of drilling mud, which are used to drilling intervals of permafrost rocks; the importance of wellbore stability is noted. Wedescribethemain technologies, which have been being applied in the north of Western Siberia; these technologies are aimed at minimizing the loss wellbore stability due to violation of the temperature conditions in the well. We also analyze hydrocarbon systems, taking into account foreign experience, which is based on prospecting and exploratory drilling of ice deposits in Greenland and Antarctica. The article draws your attention to using synthetic fluids, monoesters and chladones. The difficulties of the existing technology and the disadvantages of the hydrocarbon systems are highlighted. We propose to apply a new cryogenic drilling technology, which consists in the use of synthetic fluorine-containing agents as flushing fluid at low temperatures. The text gives valuable information on composition of the proposed flushing fluid and the prospects of using the technology to prevent complications. Much attention is given to issue of manufacturing the main chemical reagent with the reduction of the generalized production chain of its production from the starting material, it is fluorspar.

In the course of studies conducted by IAET SB RAS in the Lower Ob in 2016–2019, the understanding of the conditions for settlement of the Paleolithic population in the north of Western Siberia was significantly supplemented. Dating of a series of paleontological finds was carried out at the "Accelerated mass spectrometer of the Budker Institute of Nucle- ar Physics of SB RAS". The dates obtained show the distribution of the main representatives of the Upper Pleistocene fauna of Subarctica: Mammuthus primigenius – 50,000–15,000 BP, Coelodonta antiquitatis – 43,000–38,000 BP and 27,000–25,000 BP, Rangifer tarandus, Equus ferus – 40,000–10,000 BP, Bison sp. – 50,000–40,000 BP, Ovibos moschatus – 41,000–32,000 BP.

The activities of military topographers in Western Siberia to provide cartographic information on the foreign and domestic policies of the Russian Empire in Central Asia and Siberia in the 19th century are considered in the article. The role of information in the formation of the Russian Empire is emphasized. The contribution of the state to the organization of the study of the Asian regions of Russia and neighboring countries is noted. The establishment of the military topographic service in Western Siberia can be traced taking into account data on administrative transformations in the Siberian region, and on changes in the foreign policy of the Russian Empire. The participation of military topographers in determining and designating the state border with China is described in detail. The question of the role of military topographers in the scientific study of China and Mongolia is raised. The significance of the activities of military topographers for the policy of the Russian Empire on the socio-economic development of Siberia and the north-eastern part of the territory of modern Kazakhstan is revealed. The contribution of topographers to the construction of the Trans-Siberian railway, the design of river channels and new land routes is revealed. A large amount of literary sources, materials on the work of military topographers of Western Siberia, published in “Notes of the Military Topographic Department of the General Staff” is used in the article.
