俄罗斯天然气工业石油公司开发经济高效开发难采碳氢化合物储量的技术

作为“难采碳氢化合物开发技术”联邦项目的一部分,俄罗斯天然气工业石油公司(Gazprom Neft)开发了一套解决方案,有望在俄罗斯生产高达90亿吨的“难采”石油。该项目的成果已在汉特-曼西斯克举行的项目委员会会议上提交给俄罗斯联邦副总理亚历山大·诺瓦克

目前,俄罗斯超过60%的石油储量被归类为难储量。地质特征、深度、密度和地层渗透性低,使得开采变得复杂。开发这些储量需要先进的技术和额外的投资。该联邦项目旨在为成熟油田的“难采”碳氢化合物和剩余储量开发创造国内解决方案,于2021年在俄罗斯能源部俄罗斯天然气工业股份公司和汉特-曼西自治区政府的倡议下启动。

俄罗斯天然气工业股份公司(Gazprom Neft)与核能领域的研究和油田服务机构以及行业合作伙伴携手,开发并展示了一套俄罗斯工具的有效性,这些工具将开采难采资源的成本降低了三倍。该项目创建并测试了十多种解决方案,包括高速多级水力压裂药剂、支持压裂的数字化工具以及水平井钻井技术。这些新技术已准备好进行规模化推广,并将助力开发俄罗斯油田的阿希莫夫、秋明套层以及其他类型的“硬”储量。

作为该项目的一部分,俄罗斯天然气工业石油公司还开发并测试了用于提高采收率的俄罗斯试剂,使采收率提高了创纪录的21个百分点。该公司拥有用于表面活性剂-聚合物驱的现代材料的专利。一个科学和工业生态系统已经形成,在国家支持下,可以为化学提高采收率技术的应用创造一个新的工业领域。这些技术的大规模应用将带来额外的石油储量,并赋予西西伯利亚数十个成熟油田新的生命。

俄罗斯联邦副总理亚历山大·诺瓦克表示:“开发难采储量开采技术是俄罗斯2050年前能源战略的优先事项之一。该联邦项目为开发地质结构复杂的油田提供了解决方案,并推动了工业、石化、科研以及油气设备生产的发展。新工具的改进和推广将带来额外的预算收入、创造就业机会,并有助于加强我国的能源安全和技术主权

“难采储量是俄罗斯石油天然气工业的现在和未来。在俄气石油公司,这类储量已占其总产量的60%以上。为了提高产量,必须开发日益复杂的碳氢化合物储量。因此,我们不断探索新的、最有效的技术,以应对不同类型的难采储量。我们的合作伙伴生态系统——包括大学和研究机构、小型企业和设备制造商——都参与其中,致力于解决这一问题。该联邦项目的实施为俄罗斯高科技油田服务市场的发展、水力压裂设备和提高采收率药剂的国产化做出了重大贡献。联邦项目成功完成后,难采储量新技术的开发工作必将继续进行。”俄气石油公司管理委员会主席亚历山大·久科夫表示。

“我们深知,必须开发高科技解决方案,探索新的技术途径,以提高开发难采储量的经济效益。尤格拉已完成的联邦项目已证明,当俄罗斯联邦的支持措施与区域层面的措施相结合时,其有效性已得到体现。税收优惠政策使企业能够拨出资金,用于开发独特的技术和创新解决方案。我们将继续与尤格拉政府、俄罗斯联邦能源部、财政部以及我们的石油公司合作,将尤格拉地区作为试点项目,开发有助于在难采油田开采碳氢化合物的模式。”汉特-曼西自治区尤格拉区长鲁斯兰·库哈鲁克表示。

Gazprom Neft Develops Technologies for Cost-Effective Development of Hard-to-Recover Hydrocarbon Reserves

Gazprom Neft, as part of the federal project “Technologies for the Development of Hard-to-Recover Hydrocarbons”, has developed a set of solutions that will make it possible to bring up to 9 billion tonnes of “hard” oil into production in Russia. The results of the program were presented to Alexander Novak, Deputy Prime Minister of the Russian Federation, at a meeting of the project committee in Khanty-Mansiysk.

Currently, over 60% of Russia’s oil reserves are classified as hard-to-recover. Production is complicated by geological features, depth, density, and low permeability of the formations. Developing these reserves requires advanced technologies and additional investments. The federal project, aimed at creating domestic solutions for the production of “hard” hydrocarbons and residual reserves at mature fields, was launched in 2021 at the initiative of the Ministry of Energy of Russia, Gazprom Neft, and the Administration of Khanty-Mansi Autonomous Okrug–Yugra.

Together with research and oilfield service organizations and industry partners from the nuclear sector, Gazprom Nefthas developed and demonstrated the effectiveness of a suite of Russian tools that have reduced the cost of producing hard-to-recover resources by three times. Within the project, more than ten solutions were created and tested, including high-speed multistage hydraulic fracturing, reagents, and digital tools to support fracturing, as well as technologies for drilling horizontal wells. The new technologies are ready for scaling and will help develop Achimov, Tyumen Suite, and other types of “hard” reserves at Russian fields.

As part of the project, Gazprom Neft also developed and tested Russian reagents for enhanced oil recovery, which increased the oil recovery factor by a record 21 percentage points for the domestic industry. The company has patented modern materials for surfactant-polymer flooding. A scientific and industrial ecosystem has been formed that, with state support, can create a new industrial segment for the implementation of chemical enhanced oil recovery technologies. Their large-scale implementation will bring additional oil reserves into development and give a second life to dozens of mature fields in Western Siberia.

“The development of technologies for producing hard-to-recover reserves is one of the priorities of Russia’s energy strategy until 2050. The federal project has made it possible to create solutions for developing fields with complex geological structures and has given impetus to the development of industry, petrochemicals, scientific research, and the production of oil and gas equipment. The improvement and scaling of new tools will provide additional budget revenues and create jobs, as well as contribute to strengthening the energy security and technological sovereignty of our country,” said Alexander Novak, Deputy Prime Minister of the Russian Federation.

“Hard-to-recover reserves are the present and future of the Russian oil and gas industry. At Gazprom Neft, they already account for more than 60% of production. To increase production volumes, it is necessary to bring increasingly complex hydrocarbon reserves into development. Therefore, we are constantly searching for new, most effective technologies to work with different categories of hard-to-recover reserves. A whole ecosystem of our partners is involved in solving this problem—these are universities and research organizations, small businesses, and equipment manufacturers. The implementation of the federal project has made a significant contribution to the development of the Russian high-tech oilfield services market, the localization of production of equipment for hydraulic fracturing, and reagents for enhanced oil recovery. After the successful completion of the federal project, work on creating new technologies for the development of hard-to-recover reserves will certainly continue,” said Alexander Dyukov, Chairman of the Management Board of Gazprom Neft.

“We understand that it is necessary to create high-tech solutions and find new technological approaches that will improve the economic efficiency of developing hard-to-recover reserves. The federal project completed in Yugra has shown its effectiveness when measures of support from the Russian Federation are combined at the regional level. Tax incentives have allowed companies to allocate funds for the development of unique technological and innovative solutions. We will continue to cooperate between the Government of Yugra, the Ministry of Energy of the Russian Federation, the Ministry of Finance, and our oil companies to consider the territory of Yugra as a pilot project for developing models that will help in the production of hydrocarbons at fields classified as hard-to-recover,” said Ruslan Kukharuk, Governor of Khanty-Mansi Autonomous Okrug–Yugra.
