Проблема сальникообразования является критической при бурении скважин, особенно на месторождениях Западной Сибири (ХМАО, ЯНАО) с преобладанием высокопластичных глинистых отложений баженовской и кузнецовской свит, где традиционные методы показывают недостаточную эффективность. Согласно анализу промысловых данных 2024 года экономические потери от сальникообразования составляют 4,7 млрд рублей, при этом до 34 % случаев прихватов инструмента связаны с налипанием глинистого шлама. Цель работы систематизация причин сальникообразования, оценка эффективности новых химических реагентов для его предотвращения и разработка комплексного подхода к контролю параметров бурения для минимизации рисков осложнений. Исследование основано на анализе промысловых данных за 2024 год, лабораторных испытаниях и промысловых испытаниях трех новых классов химических реагентов: наноструктурированного ингибитора на основе модифицированного органосиликата (OSI-2024), гибридного состава с графеновыми нанопластинками (GNP-Inhibitor) и антиадгезионного комплекса на базе фторированных полимеров (PTFE-complex). Установлено, что применение OSI-2024 снижает адгезионную прочность глины к металлу на 68 % и толщину налипшего слоя на 74 % по сравнению с традиционными составами. GNP-Inhibitor продемонстрировал эффективность в условиях высоких температур (до 135 °C) с сохранением ингибирующих свойств на уровне 91 %. PTFE-complex показал высокую эффективность для экстремально липких глин типа «гамбо» при повышенной скорости проходки. Общий экономический эффект от внедрения реагентов превышает затраты в 4,7 раза. Предложенные инновационные реагенты и разработанные рекомендательные мероприятия обеспечивают комплексный подход к минимизации риска прихватов инструмента, оптимизации режимов бурения и повышению эффективности разработки месторождений, что подтверждает высокую целесообразность их промышленного использования.

Bit balling remains a significant challenge in drilling, particularly in the oil fields of Western Siberia (Khanty-Mansi and Yamalo-Nenets Autonomous Okrugs). This problem is especially critical within the highly plastic clayey deposits of the Bazhenov and Kuznetsk formations, where tradional methods are ineffective. Analysis of field data from 2024 revealed that bit balling caused economic losses of 4.7 billion rubles. Notably, 34% of all tool sticking events are associated with clay cuttings adhesion. This article aims to systematize the causes of bit balling, evaluate the performance of new chemical additives for its prevention, and develop an integrated approach to drilling parameter control in order to minimize the risk of drilling complications. The study relies on an analysis of 2024 field data as well as laboratory and field testing of three new classes of chemical additives. These classes include a nanostructured inhibitor based on modified organosilicate (OSI-2024), a hybrid inhibitor containing graphene nanoplatelets (GNP-Inhibitor), and an anti-adhesion formulation based on fluorinated polymers (PTFE-complex). The study demonstrates that OSI-2024 reduces the adhesive strength between clay and metal by 68 % and decreases the thickness of the adhered clay layer by 74% compared with conventional formulations. GNPInhibitor shows 91% of its inhibitive performance at temperatures up to 135°C. PTFE-complex shows high efficiency when drilling through highly adhesive gumbo clays at high rates of penetration. The overall economic effect of implementing the additives exceeds their cost by a factor of 4.7. These innovative chemicals and operational recommendations provide a comprehensive approach to reducing drill string sticking, optimizing drilling performance, and improving field development efficiency. Thus, they demonstrate strong potential for industrial application.
