Abstract The main goal is to assess the oil and gas potential of the basement of the southern part of the Siberian Platform as an additional source for the long-term filling of the East Siberia–Pacific Ocean pipeline with hydrocarbons. The initial reserves in the fields, which were discovered in the sedimentary cover on the Siberian Platform, are far below the reserves of the fields of Western Siberia and the Volga Region, where the drilling of deep wells showed the connection of reserves with the basement; the reserves are renewed in a natural way. On the Siberian Platform, the drilling usually ended at the “cover–basement” boundary (at the most productive level). In the wells, there are the following signs that indicate the oil and gas potential of the basement: “black” zircons in granitoids containing radioactive elements, multi-layered oil reservoirs, which are associated with deep faults, and mantle fluids bearing hydrogen and liquid hydrocarbons. Based on the signs listed, which indicate the promising basement rocks, it is necessary to change the existing methods for prospecting and evaluating oil in the sedimentary cover and to focus on the exploration of heavy deep oil in the basement rocks.

西伯利亚地台南部基底油气潜力评价及深层石油勘探

摘要 主要目标是评估西伯利亚地台南部基底的油气潜力，作为长期向东西伯利亚-太平洋管道填充碳氢化合物的额外来源。在西伯利亚地台沉积盖层中发现的油田初始储量远低于西西伯利亚和伏尔加地区油田的储量，深井钻探显示储量与基底相联系；储备以自然方式更新。在西伯利亚平台上，钻探通常在“覆盖层-基底”边界处结束（在最高生产水平）。在井中，有以下迹象表明地下室的油气潜力： 含有放射性元素的花岗岩中的“黑色”锆石，与深断层相关的多层油藏，以及含有氢和液态烃的地幔流体。根据所列出的表明基岩有前景的迹象，需要改变现有的沉积盖层石油勘探评价方法，重点勘探基岩深层稠油。
