      <abstract xml:lang="ru">
        <p>Статья посвящена решению важной задачи обеспечения точности инклинометрических измерений при строительстве наклонно направленных и горизонтальных скважин в условиях Крайнего Севера и арктического шельфа России. В этих регионах традиционные методы инклинометрии, основанные на акселерометрах и магнитометрах, сталкиваются с существенными сложностями, вызванными значительными изменениями геомагнитного поля (магнитными бурями, вековыми вариациями и прочими возмущениями). Погрешности измерения азимута ствола скважины из-за искажений геомагнитного поля приводят к рискам отклонения от проектной траектории, что ведет к финансовым и технологическим потерям. Проведен детальный анализ и сформулированы требования к использованию актуальных геомагнитных данных и высокоточных математических моделей, являющихся основой для коррекции инклинометрических замеров при горизонтальном бурении в условиях экстремальных широт. Для компенсации внешних магнитных возмущений в Арктике недостаточно использовать устаревшие или глобальные модели (IGRF), необходимы локальные, регулярно обновляемые модели высокого разрешения (аналогичные HRGM, IFR-1, IFR-2), учитывающие региональную специфику и локальные магнитные аномалии земной коры. Представлены отечественные геомагнитные модели (CAMPUS-C, CAMPUS-A, CAMPUS-CA, DIF-1), разрабатываемые Геофизическим центром РАН и Институтом нефтегазовой геологии и геофизики СО РАН для нефтегазового комплекса, и впервые обоснована их применимость в качестве замены зарубежных моделей BGGM/HDGM для задач наклонно направленного бурения в арктических условиях. Предложены новые отечественные геомагнитные модели и детальное обоснование оптимального количества и расположения геомагнитных обсерваторий, необходимых для обеспечения надежного мониторинга магнитной обстановки. Применение таких специализированных моделей и данных позволяет нивелировать влияние геомагнитных помех, обеспечивая достоверность определения пространственного положения бурового инструмента при горизонтальном бурении. Это способствует оптимизации процессов бурения, повышению безопасности и эффективности освоения месторождений Арктики, что имеет стратегическое значение для Российской Федерации.</p>

      <abstract xml:lang="en">
        <p>This article addresses the important challenge of ensuring accurate inclinometer measurements during the construction of directional and horizontal wells in the Far North and Arctic shelf of Russia. In these regions, traditional inclinometer methods based on accelerometers and magnetometers face significant challenges due to significant changes in the geomagnetic field (magnetic storms, secular variations, and other disturbances). Wellbore azimuth measurement errors due to geomagnetic field distortions lead to risks of deviation from the planned trajectory, resulting in financial and techno-logical losses. A detailed analysis has been conducted and requirements for the use of up-to-date geomagnetic data and high-precision mathematical models have been formulated, providing the basis for correcting inclinometer measurements during horizontal drilling at critical latitudes. It is not enough to use outdated or global models (IGRF) in order to compensate for external magnetic disturbances in the Arctic: local, regularly updated high-resolution models (similar to HRGM, IFR-1, IFR-2), taking into account the regional particularities and local lithospheric magnetic anomalies, are needed. The national geomagnetic models (CAMPUS-C, CAMPUS-A, CAMPUS-CA, DIF-1), developed by the Geophysical Center of the RAS and the Institute of Petroleum Geology and Geophysics SB RAS for the oil and gas industry, are presented, and for the first time their applicability as a replacement for foreign models (BGGM/HDGM) for directional drilling tasks in the Arctic conditions is substantiated. The new national geomagnetic models and a detailed justification for the optimal number and location of geomagnetic observatories necessary to ensure reliable monitoring of the magnetic environment are proposed. The application of such specialized models and data helps mitigate the effects of geomagnetic interference, ensuring reliable determination of the drilling tool’s spatial position during horizontal drilling. This helps optimize drilling processes and improve the safety and efficiency of Arctic field development, which is of strategic importance for the Russian Federation.</p>
