Изобретение относитс к устройствам дл бурени скважин во льду электротермическим способом с образованием керна.This invention relates to an apparatus for drilling wells in ice by an electrothermal method with the formation of a core.
По основному авт. св. № 350945 известно устройство дл электротермического бурени скважин во льду с образованием керна , состо щее из кольцевого полого корпуса, в полости которого соосно с ним смонтирован р д медных колец с расположенным между ними нагревательным элементом, корпус выполнен в виде конуса с выведением наружу в торце медным кольцом 1.According to the main author. St. No. 350945, a device for electrothermal drilling of wells in ice with the formation of a core, consisting of an annular hollow body, in the cavity of which a row of copper rings with a heating element located between them is mounted coaxially with it, the body is made as a cone with copper out ring 1.
Это устройство показывает надежно и эффективно, однако при бурении холодного льда в случае обрыва электропитани отмечаетс быстрое замерзание прослойки талой воды, заключенной между стенками устройствами и лед ным забоем. Это вызывает приморажение бурового снар да, что создает аварийную ситуацию и приводит к потере бурового снар да.This device shows reliably and efficiently, however, when drilling cold ice in the event of a power failure, there is a rapid freezing of a layer of melt water enclosed between the walls of the devices and the ice face. This causes the drill to freeze, which creates an emergency situation and leads to the loss of the drill string.
Целью изобретени вл етс повышение надежности работы бурового снар да.The aim of the invention is to improve the reliability of operation of the drill string.
Цель достигаетс те.м, что устройство снабжено металлическими чехлами, которыеThe goal is achieved by the fact that the device is equipped with metal covers that
установлены на внутренней и наружной конических поверхност х корпуса с зазором.mounted on the inner and outer conical surfaces of the housing with a gap.
При использовании чехлов антифриз по каналам поступает к торцу устройства, вытекает непосредственно на забой и, смешива сь с талой водой, образует незамерзающий раствор, который заполн ет все призабойное пространство и обеспечивает непримерзание устройства в случае обрыва электропитани .When using covers, the antifreeze flows through the channels to the end of the device, flows directly to the bottom, and, mixing with the melt water, forms an ice-free solution that fills the entire bottom hole space and ensures that the device does not freeze in the event of a power failure.
Устройство, которое снабжено чехлами, обладает повышенной надежностью, обеспечивает непримерзаемость бурового снар да, при этом не измен ютс ни скорость бурени , ни диаметр скважины и керна.The device, which is equipped with covers, has increased reliability, provides an unprecedented drill bit, while neither the drilling rate, nor the diameter of the well and core are changed.
На чертеже изображено устройство, разрез .The drawing shows the device section.
Устройство состоит из стального корпуса 1 с крыщкой 2, медных колец-тепловодов 3 с расположенным между ними нагревательным элементом 4. В крышке 3 сделаны 20 отверсти 5 дл подвода антифриза. На внутренней 6 и наружной 7 конических поверхност х корпуса 1 закреплены металлические чехлы 8 таким образом, что между че.члами 8 и корпусом 1 устройства образуетс The device consists of a steel case 1 with a lid 2, copper rings-teploodov 3 with a heating element 4 located between them. The cover 3 has 20 holes 5 for supplying antifreeze. Metal covers 8 are fixed on the inner 6 and outer 7 of the conical surfaces of the housing 1 in such a way that between chuch 8 and the housing 1 of the device
