???? 據(jù)全球能源新聞網(wǎng)2月26日報道，俄羅斯天然氣工業(yè)石油公司(Gazprom Neft)在2020年削減了非傳統(tǒng)石油生產(chǎn)成本，將其降至每噸1.3萬盧布，并在2019年的基礎上削減了20%的成本。預計到2021年底，生產(chǎn)成本將達到每噸8500盧布，這使得該公司可以在基礎設施已經(jīng)成熟的油田開始Bazhenov地層的商業(yè)化生產(chǎn)。
????俄氣石油技術伙伴關系(該公司的工業(yè)集成中心,以前稱為Bazhen技術中心)實現(xiàn)了2020年在Bazhenov地層產(chǎn)量同比增長78%,達到10萬噸,這是開發(fā)非傳統(tǒng)碳氫化合物的新技術解決方案，使該企業(yè)能夠將生產(chǎn)Bazhenov石油的成本減少一半以上，從項目啟動時的3萬盧布減少到2021年的1.3萬盧布。
????2020年，還在坎蒂-曼西自治州奧克魯格-尤格拉（Khanty-Mansi Autonomic Okrug-Yugra）的Palyanovskoye油田建造了一口高技術井，涉及兩公里橫軸、30級水力壓裂和高速注液（每分鐘16立方米），這是第一次完全由俄羅斯生產(chǎn)的設備進行這類復雜的所有作業(yè)。
????俄氣石油預計將在2021年完成一系列解決方案的測試，以實現(xiàn)Bazhenov石油的可行性生產(chǎn)。Palyanovskoye油田將鉆探8口井，以最終確認開發(fā)非傳統(tǒng)儲量的商業(yè)技術的有效性。完成這項試驗，并將非傳統(tǒng)石油生產(chǎn)成本降低到每噸8500盧布，將使Bazhenov油氣在西伯利亞西部油田的基礎設施已經(jīng)就位的情況下開始可行性的生產(chǎn)。
????俄氣石油技術開發(fā)總監(jiān)阿列克謝·瓦什凱維奇（Alexey Vashkevich）表示，我們在為開發(fā)“難以開采”的石油創(chuàng)造動力以及將生產(chǎn)成本減半方面取得了長足的進步——而且，在這個時候，開發(fā)非傳統(tǒng)儲量所需的高技術油井的進口替代水平達到95%以上。
????我們參與開發(fā)的許多解決方案在整個行業(yè)是無與倫比的。部署開發(fā)Bazhenov地層的商業(yè)技術，到2025年，不僅可以從這些儲量中每年獲得100萬噸的額外產(chǎn)量，而且還可以打開西伯利亞西部其他致密儲量的通道。
????Bazhenov地層或 Bazhenov頁巖是西伯利亞盆地的一個地質層。它是由蒂托尼亞-早貝里亞斯時期沉積在深海中的沉積物形成的。根據(jù)美國能源信息署(U.S. Energy Information Administration) 2013年6月公布的數(shù)據(jù)顯示，Bazhenov頁巖勘探區(qū)致密油儲量約為1.243萬億桶。

????GAZPROM NEFT DOUBLES PRODUCTION OF BAZHENOV TIGHT OIL IN WESTERN SIBERIA
????Gazprom Neft cut its non-traditional oil production costs in 2020, taking this down to RUB13,000 per tonne and delivering a 20% reduction on 2019 costs. Production costs are expected to reach RUB8,500 per tonne by the end of 2021, allowing the company to start commercial production of Bazhenov strata at fields with developed infrastructure already in place.
????Gazpromneft-Technology Partnerships (the company’s industrial integration hub, previously known as the Bazhen Technology Centre) delivered a 78% year-on-year increase in production at Bazhenov strata in 2020, reaching 100,000 tonnes — new technological solutions for developing non-traditional hydrocarbons having allowed the business to more than halve the costs of producing Bazhenov oil, from RUB30,000 at the start of the project in 2017 to RUB13,000 by 2021.
????2020 also saw the construction of a high-tech well involving a two-kilometre horizontal shaft, 30-stage hydraulic fracking, and high-speed fluid injection (of up to 16 cubic metres per minute) at the Palyanovskoye field in the Khanty-Mansi Autonomous Okrug—Yugra — this first time all operations on such complex construction have been undertaken using exclusively Russian-produced equipment.
????Gazprom Neft is expecting to complete its testing of a range of solutions for the viable production of Bazhenov oil in 2021. Eight wells are to be drilled at the Palyanovskoye field for final confirmation of the effectiveness of commercial technology for developing non-traditional reserves. Completing this experiment, and reducing non-traditional oil production costs to RUB8,500 per tonne, will make it possible for viable production of Bazhenov hydrocarbons to commence at West Siberian fields with infrastructure already in place.
????Alexey Vashkevich Director for Technological Development, Gazprom Neft said: “We have come a long way in being able to create the impetus for developing “hard-to-recover“’ oil, as well as halving production costs — at a time, moreover, when import-substitution levels in building the high-tech wells necessary for developing non-traditional reserves reached more than 95%.
????Many of the solutions developed with our involvement are unparalleled throughout the industry. Deploying a commercial technology for developing the Bazhenov Formation will not only make it possible to produce an extra one million tonnes per year from these reserves by 2025, but will also open up access to other tight reserves in Western Siberia.“
????The Bazhenov Formation or Bazhenov Shale is a geological stratum in the West Siberian basin. It was formed from sediment deposited in a deep-water sea in Tithonian–early Berriasian time. According to U.S. Energy Information Administration estimates published in June 2013, the total Bazhenov shale prospective area has a resource of a risked tight oil in-place of 1,243 billion barrels.
