Abstract

Фитинг, предназначенный для снижения трения между бурильной колонной и стенкой буровой скважины. В первом аспекте фитинг имеет выемки, образованные вдоль высверленного отверстия фитинга, для смазывания границы раздела между фитингом и бурильной колонной для уменьшения трения. Во втором аспекте на бурильной колонне размещен фитинг, имеющий роликовое средство, которое может вращаться относительно точки вращения так, чтобы доводить до минимума как осевое, так и вращательное трение. В соответствии с третьим аспектом, фитинг содержит внутреннюю секцию, прикрепляемую к бурильной колонне или другому фитингу, и наружную секцию, способную вращаться вокруг внутренней секции. Между внутренней секцией и наружной секцией предпочтительно размещен уплотненный подшипник.Международная заявка была опубликована вместе с отчетом о международном поиске.
