Abstract

В заявке описаны система и способ ориентации перфораторов внутри наклонных или искривленных стволов скважин. В изобретении предлагается использовать расположенный внутри перфоратора дополнительный груз, создающий определенную неуравновешенность, под действием которой перфоратор ориентируется в определенном положении. Груз расположен на наружной поверхности трубы перфоратора в пределах внутреннего диаметра его корпуса. Изобретение позволяет ориентировать перфоратор в любом радиальном положении и не влияет на характеристики взрыва любого из его кумулятивных зарядов.Международная заявка была опубликована вместе с отчетом о международном поиске.
