Изобретение относитс к буровой технике, а именно к породоразрушающему инструменту вставного типа, используемому при бурении скважин без подъема бурильных труб.The invention relates to a drilling technique, namely, a plug-in type rock cutting tool used in the drilling of wells without lifting drill pipes.
Известно вставное четырехшарошечное долото , включающее полый корпус с конусным гнездом, шарошечный комплект с парой неподвижных и парой подвижных лап с шарошками , шарнирно соединенных с поршневым механизмом перевода долота в рабочее положение .A plug-in chetyrehsharoshechnoe chisel, including a hollow body with a tapered socket, a roller cone set with a pair of fixed and a pair of movable legs with cones, pivotally connected to the piston mechanism for transferring the bit into the working position.
Однако известное долото имеет ненадежное крепление подвижных лап относительно неподвижных, что снижает его стойкость.However, the known chisel has an unreliable fastening of the movable paws relatively stationary, which reduces its durability.
Цель изобретени - повысить надежность работы долота.The purpose of the invention is to improve the reliability of the bit.
Это достигаетс тем, что хвостовик неподвижных лап выполнен конусным с продольными пазами дл размеш,ени подвижных лап.This is achieved by the fact that the shank of the fixed legs is made tapered with longitudinal grooves for stirring the moving legs.
На фиг. 1 изображено предлагаемое долото, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the proposed chisel, longitudinal section; in fig. 2 is a section A-A in FIG. one.
Долото включает полый корпус 1, в нижней части которого выполнено конусное гнездо 2, а выше гнезда 2 нарезана резьба 3, шарошечный комплект с парой неподвижных лап 4, несуш ,их шарошки 5, и парой подвижных лап 6, несуш,их шарошки 7.The chisel includes a hollow body 1, in the lower part of which a tapered nest 2 is made, and above the nest 2 a thread 3 is cut, a roller cone with a pair of fixed paws 4, a layer, their cone 5, and a pair of movable paws 6, a layer, their cone 7.
Лапы 6 шарпирно соединены с поршневым механизмом 8 перевода Долота в рабочее положение . На конусном хвостовике 9 неподвижных лап 4 выполнены продольные пазы 10 дл размещени в них подвижных лап 6.The paws 6 are sharply connected to the piston mechanism 8 for converting the Chisel into the working position. On the tapered shank 9 of the fixed legs 4, longitudinal grooves 10 are made to accommodate movable legs 6 therein.
В транспортном положении подвижные лапы 6 располагаютс ниже неподвижных лап 4.In the transport position, the movable legs 6 are located below the fixed legs 4.
При прокачивании жидкости поршневой механизм 8 перевода долота в рабочее положение обеспечивает перемеш,ение подвижных лап 6 вверх, при этом лапы 6, поворачива сь вокруг шарнира И наружу, в крайнем верхнем положении вход т в пазы 10 неподвижных лап 4 и зажимаютс в конусном гнезде 2 корпуса 1.When pumping a fluid, the piston mechanism 8 for transferring the bit into the working position provides for stirring, moving paws 6 upwards, while the paws 6, turning around the hinge and outwards, in the extreme upper position, enter the grooves 10 of the fixed paws 4 and are clamped in the cone slot 2 housing 1.
При переводе долота в транспортное положение подвижные лапы 6 вывод тс из конуса путем взаимодействи их с башмаком бурильной колонны труб при подъеме долота вверх.When the bit is moved to the transport position, the movable legs 6 are pulled out of the cone by interacting with the shoe of the drill string when the bit is raised up.
