Description
Известны буровые колонковые снар ды, снабженные переходниками дл отсоединени колонны бурильных труб от нрихваченной колонковой трубы путем среза слабого звена или отвинчивани внутренней незат гивающейс резьбы.Core drills are known that are provided with adapters for disconnecting a drill string from a previously received core tube by cutting off a weak link or unscrewing an internal non-locking thread.
Предлагаемое устройство отличаетс от известных тем, что в нем, с целью отсоединени колонны бурильных труб вместе с переходником от прихваченной в скважине колонковой трубы, применен способ перерезани прихваченной трубы. Дл осуществлени процесса перерезани трубы В КОЛОНКОВОМ снар де под колонковой трубой установлен ниппель, несущий на нижнем конце фрезу в форме звезды, лучи которой на концах снабжены резцами. В нерабочем положении лучи фрезы отогнуты вверх.The proposed device differs from the known ones in that, in order to disconnect the drill pipe string together with the adapter from the core pipe stuck in the well, a method of cutting the stuck pipe is applied. In order to carry out the process of cutting the pipe, in a COLUMN snare, a nipple is installed under the core pipe, which carries a star-shaped milling cutter at its lower end, the rays of which are equipped with incisors at its ends. In the off position, the beams of the cutter are bent upwards.
На чертеже показан снар д в продольном разрезе.The drawing shows a shot in longitudinal section.
При прихвате колонковой трубы 1 колонну бурильных труб нат гивают и одновременно вращают. При этом ограничитель - нижн шайба 2 - постепенно истираетс и разрущаетс . Лучи фрезы 3 при этом распр мл ютс и перерезают колонковую трубу / ниже переходника 4. Вместо истираемой щайбы может быть установлен механический вибратор В виде двух зубчаток, при этом одна зубчатка 5 закрепл етс на ниппеле над фрезой, а втора 6-на переходнике.When a core pipe is seized, a string of drill pipes is pulled and simultaneously rotated. At the same time, the stopper - the bottom washer 2 - is gradually worn out and destroyed. The rays of the cutter 3 are then straightened and cut the column pipe / below the adapter 4. Instead of the abradable grip, a mechanical vibrator can be installed.
Предмет изобретени Subject invention
1. Буровой КОЛОНКОВЫЙ снар д, снабженный переходником с внутренней незат гивающейс резьбой, отличающийс тем, что, с целью отсоединени колонны бурильных труб вместе с переходником от прихваченной В скважине колонковой трубы путем перерезани последней, в1. A drilling column equipped with an adapter with an internal non-tapping thread, characterized in that in order to disconnect the drill string together with the adapter from a core pipe stuck in the borehole by cutting the latter into
