中國石化新聞網訊 據俄羅斯油氣網2020年11月27日莫斯科報導，俄羅斯最大的石油公司俄羅斯石油公司（俄油/Rosneft）已是北極地質調查史上第一個在喀拉海北部鑽取淺地層井的石油公司。這個地層鑽井作業是在俄油的大規模地質調查遠徵中進行的。
這個項目的主要任務是收集巖心樣。巖心是一種有價值的巖石材料，是確定所研究的北極大陸架巖石的年齡(分層)、組成和形成條件所需的地質數據的直接來源。採集的巖心樣對獲得有關北卡拉盆地地質構造和油氣潛力的最新數據非常有價值。
俄油是北極大陸架許可證最大持有者。俄油時下正在北極實施一項全面的長期研究計劃，包括地質、海洋、水文氣象和環境研究。
北卡拉盆地鑽井作業是由「Bavenit號」地質調查船進行的，這是俄羅斯裝備最齊全的地質調查船之一。在這次地層調查遠徵中，俄油完鑽了8口井，井深90米。這是北極地區和俄羅斯大陸架最北端的第一批井。實地調查是在符合最高標準的環境安全和環境保護的情況下進行的。
俄油在此次地層調查遠徵中總共取巖心樣6.5噸，並在不同屬性的礦床(如陸源巖石和碳酸鹽巖石)以及在更具挑戰性的分散和半巖心礦床中測試了鑽井技術。專門設計的鑽頭用於巖石和半巖石地層。
所採集的巖心樣將藉助於俄羅斯國家智力資源基金會（Innopraktika）和羅蒙諾索夫莫斯科國立大學地質學院進行實驗室測試。一系列的分析研究將提高北極不同時代沉積盆地油氣潛力預測的可靠性，並為北卡拉地區提供新的地質模型。
調查遠徵期間獲得的經驗為開發有效研究北極大陸架的技術和在北極東部日益嚴峻的條件下繼續這個項目提供了基礎。

Rosneft conducts stratigraphic drilling on Arctic shelf
Rosneft has been the 1st in the history of Arctic surveys to drill shallow stratigraphic wells in the north of the Kara Sea. The work has been carried out during its vast research expedition.
The project’s main task was to collect core samples. The core is a valuable rock material, a direct source of geological data required to determine the age (stratification), composition and conditions of formation for Arctic shelf rocks under research. The samples recovered are of great interest for the purpose of obtaining the latest data on the geological structure and oil and gas potential of the North-Kara basin.
Rosneft is the largest license holder for continental shelf areas. The company is implementing a comprehensive long-term research programme in the Arctic, which includes geological, oceanological, hydrometeorological and environmental studies.
The North-Kara drilling was performed with the Bavenit survey drill ship, one of the most equipped vessels in Russia. During the expedition, 8 wells were drilled to a depth of 90 m. Those were the 1st in the region and the northernmost on the Russian shelf. The fieldwork was carried out in compliance with the highest standards of environmental safety and environmental protection.
In total, 6.5 tonnes of core were sampled, and the drilling technology was tested in deposits with varying properties, such as rocky terrigenous and carbonate ones, as well as in more challenging dispersion and semi-core deposits. Specially designed drill bits were used for rocky and semi-rocky formations.
The core samples taken will be lab-tested by means of Innopraktika and the Lomonosov Moscow State University Faculty of Geology. A series of analytical studies will improve the reliability of forecasts of the oil and gas potential of the Arctic’s sedimentary basins of varying ages and provide a new geological model of the North-Kara region.
The experience gained during the expedition provides the basis to develop technologies for effective study of the Arctic shelf and to continue the project in the increasingly severe conditions of the Eastern Arctic.
