Изобретение относитс к области бурени скважин, a именно, к устройствам дл расширени скважин, используемым при турбинном бурении скважии без подъема бурильных труб на поверхность.The invention relates to the field of drilling wells, namely, devices for expanding wells used in turbine drilling of a well without lifting drill pipes to the surface.
Известен раздвижной расширитель, извлекаемый через трубы, содержащий, корпус, шток с , расшир ющие рабочие органы на подпружиненных лапах, шарнирйо установленных в пазах корпуса (1.Known sliding expander, retrieved through the pipe, containing, body, stem with, expanding the working bodies on the spring-loaded legs, pivotally mounted in the slots of the body (1.
Недостаток указанного раздвижного расшнрнтел заключаетс в ненадежности работы изза сложности перевода расщир ю щн;( рабочих органов из транспортного в рабочее Положение.The disadvantage of this sliding extension is in the unreliability of work due to the difficulty of converting the expansions; (working bodies from the transport to the working position.
Наиболее близким по технической сущности и достигаемому результату вл етс вставной лопастной расширитель, содержащий корпус, шток с поршнем, подпружиненные лопастн, шарнирно установленные в каретках штока н размещенные в пазах корпуса 2.The closest in technical essence and the achieved result is a plug-in blade expander, comprising a housing, a piston rod, spring-loaded blades, hingedly mounted in the carriages of the rod and placed in the slots of the housing 2.
Вставной расширитель работает следующим образом.Plug-in extender works as follows.
Подпружиненные лопасти расщирител в процессе работы, перемеща сь в продольных пазах корпуса, взаимодействуют с башмаком обсадной колонны, передающим осевую нагрузку и вращательный момент. Шарннрное соединение в нижней частн лопасти со штоком расширител позвол ет увеличить ее рабочую и калибрующую поверхности.Spring-loaded blades of the sweeper during operation, moving in the longitudinal grooves of the body, interact with the casing shoe, which transfers axial load and rotational moment. The hinge joint in the lower part of the blade with the expander stem allows to increase its working and gage surfaces.
Недостаток этого расширител заключаетс The disadvantage of this extender is
в том, что дл перевода лопастей и закреплени in that for translating blades and securing
их в рабочем положении необходимо наличиеthey must be in working position
дополнительной подвижной системы деталей,additional moving parts system
что снижает надежность работы расширител .which reduces the reliability of the expander.
К тому же взаимодействие лопастей расширител с башмаком обсадной колонйы в процессе работы не позвол ет использовать расшнрнтель совместно с турбобуром.In addition, the interaction of the blades of the expander with the casing shoe during operation does not allow the use of the extender in conjunction with the turbo-drill.
Целью изобретени вл етс повышение Hiдежности работы расширител .The aim of the invention is to increase the high performance of the expander.
Это достигаетс тем, что концева часть каждой лопасти .выполнена с заплечиками, a корпус -с соответствующими выступами в пазах .This is achieved by the fact that the end part of each blade is made with shoulders, and the casing with corresponding protrusions in the slots.
