Description
Известные устройства дл среза труб в скважинах, основанные на использовании энергии взрывчатого вещества, требуют герметизации этого вещества толстостенным кожухом, который после взрыва засор ет скважину кусками металла и ослабл ет действие взрывной волны.The known devices for cutting pipes in wells, based on the use of explosive energy, require that the material be sealed with a thick-walled casing, which, after the explosion, clogs the well with metal pieces and weakens the effect of the blast wave.
Предлагаемый зар д не имеет этого недостатка, так как он выполнен в виде диска с прикрепленными к его боковой поверхности отдельными металлическими пластинками, которыми производитс перерезание трубы.The proposed charge does not have this drawback, since it is made in the form of a disk with separate metal plates attached to its side surface, which are used to cut the pipe.
На чертеже показана конструктивна схема предлагаемого зар да.The drawing shows the structural scheme of the proposed charge.
Зар д / представл ет собой цилиндрическую щащку прессованного взрывчатого вещества, к цилиндрической поверхности которой приклеены отдельные плоские металлические пластинки 2. Дл инициировани взрыва зар да служит электродетонатор 5.Zar d / is a cylindrical pin of an extruded explosive, to the cylindrical surface of which separate flat metal plates 2 are glued. An electric detonator 5 serves to initiate a charge explosion.
При взрыве зар да металлические пластинки приобретают больщую скорость и, облада больщим запасом кинетической энергии, при встрече с трубой 4 пробивают последнюю, т. е. срезают ее.When the charge explodes, the metal plates acquire a greater speed and, possessing a large supply of kinetic energy, they pierce the latter when they meet a pipe 4, i.e. they cut it off.
Предмет изобретени Subject invention
Зар д дл среза труб, представл ющий собой щащку взрывчатого вещества с установленным в ее центре герметичным электродетонатором, отличающийс тем, что он выполнен в виде диска с прикрепленными к его боковой поверхности отдельными металлическими пластинками, которыми под давлением продуктов взрыва производитс -перерезани трубы.Charge for cutting pipes, which is an explosive crater with a sealed electric detonator installed at its center, characterized in that it is made in the form of a disk with separate metal plates attached to its side surface, which under pressure of the explosion products is produced by cutting the pipe.
