Abstract

Изобретение относитс  к буровой технике и позвол ет исключить резкие перегибы ствола при бурении скважины. Дл  этого установленные на концах трубчатого корпуса два отклон ющих узла в виде искривленных переводников смещены относительно друг друга в окружном направлении . Переводники жестко св заны с торцами корпуса. При спуске устройства в скважину его искривленна  нижн   часть ориентируетс  и устанавливаетс  по направлению необходимого азимута искрнвлени  ствола. Верхний переводник устанавливают в плоскости существующего искривлени . Происходит смещение оси нижней части устройства относительно ствола скважины, что вызывает по вление отклон ющих сил. В результате при проводке скважин траектори  ее ствола получаетс  плавной. 3 ил. (ЛThe invention relates to a drilling technique and makes it possible to eliminate sharp bends in the wellbore when drilling a well. For this, the two deflection assemblies mounted at the ends of the tubular body in the form of curved subs are displaced relative to each other in the circumferential direction. The riders are rigidly connected to the ends of the body. When the device is lowered into the well, its curved lower part is oriented and set in the direction of the required azimuth of the spark. The upper sub is installed in the plane of the existing curvature. The axis of the lower part of the device is displaced relative to the wellbore, which causes the appearance of deflection forces. As a result, when drilling wells, the trajectory of its wellbore is smooth. 3 il. (L
