Results of the 5G borehole drilling at russian antarctic station «Vostok» and researches of ice cores

Article preview

We produce an information about results and features of the 5G borehole drilling in Antarctic layer at Russian station Vostok. Main regularities of the change structured and physical properties by Antarctic ice layer depth, which determine mechanical and reological properties if ice, which influence to sinking of a borehole and to the maintaining of it in a working condition, the safe and competitive technologies creation for drilling of strong ice layers and the environmentally safe technology of the subglacial reservoirs unsealing. We also produce results of the ice cores researching and the paleoclimatic raws construction, which are reconstructed by the ice cores researching from Vostok station, which is compared with isotopic graph. This graph describes changes of World ocean level.

Directional drilling in ice caps

Article preview

Directional drilling technology can be used in glacier boreholes to obtain additional ice cores and to pass over sticking drills. Experimental sidetracking of 5G-2 hole in the deep borehole at Vostok station, Antarctica, showed the high efficiency of the directional drilling without using of special whip-stocks to deviate the hole.
