Abstract

La présente invention concerne un derrick de forage (20) télescopique à quatre côtés et un procédé de montage correspondant. Ce derrick (20), conçu pour être placé sur un terrain de forage au-dessus d'un trou de forage, et capable de résister à des conditions climatiques, atmosphériques ou géologiques très difficiles, est constitué de plusieurs sections, à savoir une section de base (22), une section sommet (30) et au moins une section intermédiaire (26, 28), toutes ces sections se superposant au-dessus de la section de base (22) pour former une tour verticale à quatre côtés. Chaque section est constituée d'éléments verticaux se plaçant au quatre coins (38a-38d) de chacune des sections, de façon à former un total de quatre côtés (40a-40d) en périphérie de chaque section. Une fenêtre (46) présente un côté suffisamment grand pour recevoir successivement par dessous au moins une section. Dès lors, chacune des sections intermédiaires (26, 28) s'introduit dans la section de fond (22), permettant ainsi la montée télescopique en série des sections intermédiaires (26, 28).
