Изобретение относитс к области горного дела и предназначено дл бурени параллельных перекрывающихс скважин.The invention relates to the field of mining and is intended for drilling parallel overlapping wells.
Известны устройства дл направленного бурени параллельных перекрывающихс скважин при бурощнековой выемке, включающие кондуктор желобчатого типа.Devices are known for the directional drilling of parallel overlapping wells with auger notch, including a grooved conductor.
Целью изобретени вл етс снижение трудоемкости работ при бурении скважин больщого диаметра.The aim of the invention is to reduce the labor intensity in the drilling of large diameter wells.
Это достигаетс тем, что кондуктор выполнен в виде двух щарнирно соединенных между собой желобов.This is achieved by the fact that the jig is made in the form of two gutters that are hinged together.
На чертеже изображена принципиальна схема устройства.The drawing shows a schematic diagram of the device.
Устройство состоит из желоба 1, наружна иоверхнсть которого выполнена по радиусу скважины, и желоба 2 с радиусом кривизны, равным радиусу скважины. Центр кривизны желоба совпадает с центром соседней пробуриваемой скважины. Желобы / и 2 соедпненыThe device consists of a groove 1, the outer surface of which is made along the well radius, and the groove 2 with a radius of curvature equal to the well radius. The center of curvature of the gutter coincides with the center of the adjacent drilled well. Gutters / and 2 connections
между собой шарниром 3. Между желобами расположен эластичный баллон 4.between the hinge 3. Between the grooves is an elastic cylinder 4.
Устройство в сложенном виде ввод т в пробуренную бурошнековой мащиной скважину. Цри заполнении эластичного баллона жидкостью или газом поворачивают желоб 2 вокруг шарнира 3 до упора в стенку скважины. Соседнюю скважину пробуривают по желобу 2, использу его как кондуктор.The device is folded and injected into a well drilled with an auger. When filling an elastic cylinder with liquid or gas, turn the chute 2 around the hinge 3 until it stops against the borehole wall. A neighboring well is drilled along chute 2, using it as a conductor.
Предмет изобретени Subject invention
Устройство дл направленного бурени параллельных перекрывающихс скважин при бурошиечовой выемке, включающее кондуктор желобчатого типа, отличающеес тем, что, с целью снижени трудоемкости работ при бурении большого диаметра, кондуктор выполнен в внде двух щарнирно соединенных мсжлу собой желобов.A device for directional drilling of parallel overlapping wells in a buroshiechaya groove, including a grooved conductor type, characterized in that, in order to reduce the labor intensity of operations in drilling large diameters, the conductor is made in the interior of two grooves connected together.
