Claims (2)

1. Стабилизатор нижней части бурильной колонны, включающий корпус с осевым промывочным каналом и присоединительными резьбами, с двумя лопастями, армированными вставками из износостойкого материала, отличающийся тем, что стабилизатор выполнен неравножестким при изгибе с поперечным сечением в форме кольца со срезанными с противоположных сторон сегментами, причем наружный диаметр кольца соответствует диаметру используемого долота.1. The stabilizer of the lower part of the drill string, comprising a housing with an axial flushing channel and connecting threads, with two blades reinforced with inserts of wear-resistant material, characterized in that the stabilizer is made uneven when bent with a cross section in the form of a ring with segments cut off from opposite sides, moreover, the outer diameter of the ring corresponds to the diameter of the bit used. 2. Стабилизатор по п. 1, отличающийся тем, что его жесткость при изгибе относительно одной из главных центральных осей инерции в 2,0 - 2,5 раза меньше, чем относительно другой и в 1,2 - 1,5 раза меньше, чем жесткость применяемых с ним утяжеленных бурильных труб. 2. The stabilizer according to claim 1, characterized in that its bending stiffness relative to one of the main central axes of inertia is 2.0 to 2.5 times less than relative to the other and 1.2 to 1.5 times less than rigidity of the weighted drill pipes used with it.
