Claims (8)

1. Устройство уплотнения места пересечения главной буровой скважины и буровой скважины ответвления, включающее в себя секцию главной обсадной трубы, предназначенную для размещения в главной буровой скважине в зоне места ответвления, и секцию обсадной трубы ответвления, предназначенную для размещения в буровой скважине ответвления и скрепленную с секцией главной обсадной трубы, при этом секция главной обсадной трубы имеет трубчатую форму со скошенной поверхностью, приспособленной для взаимодействия со скошенной поверхностью клинообразного элемента.1. A device for sealing the intersection of the main borehole and the branch borehole, comprising a section of the main casing intended for placement in the main borehole in the area of the branch, and a section of the casing of the branch intended for placement in the borehole of the branch and fastened to section of the main casing pipe, while the section of the main casing pipe has a tubular shape with a beveled surface adapted to interact with the beveled surface of the wedge znogo element. 2. Устройство по п. 1, отличающееся тем, что клинообразный элемент выполнен с возможностью расположения в главной скважине, примыкающим к секции главной обсадной трубы так, что скошенная поверхность на одном конце клинообразного элемента находится перед скошенной поверхностью секции главной обсадной трубы. 2. The device according to p. 1, characterized in that the wedge-shaped element is arranged to be located in the main well adjacent to the section of the main casing so that the beveled surface at one end of the wedge-shaped element is in front of the beveled surface of the section of the main casing. 3. Устройство по п. 2, отличающееся тем, что клинообразный элемент является полым отклонителем, имеющим скошенную поверхность, которая пересекает центральную ось цилиндрической поверхности отклонителя, по существу, под тем же самым углом, что и угол пересечения между скошенной поверхностью секции главной обсадной трубы и центральной осью секции главной обсадной трубы. 3. The device according to claim 2, characterized in that the wedge-shaped element is a hollow deflector having a beveled surface that intersects the central axis of the cylindrical surface of the deflector, essentially at the same angle as the intersection angle between the beveled surface of the section of the main casing and the central axis of the section of the main casing. 4. Устройство по п. 3, отличающееся тем, что отклонитель расположен под секцией главной обсадной трубы и имеет меньшую внутреннюю ширину, чем внешняя ширина носовой части секции обсадной трубы ответвления, и отклонитель размещен в главной буровой скважине, по крайней мере частично, под пересечением с буровой скважиной ответвления, и ориентирован так, что, когда секцию обсадной трубы ответвления опускают через главную скважину, носовая часть ее будет отклоняться скошенной поверхностью отклонителя в буровую скважину ответвления. 4. The device according to p. 3, characterized in that the diverter is located under the section of the main casing pipe and has a smaller internal width than the outer width of the bow of the section of the casing branch, and the diverter is placed in the main borehole, at least partially, at the intersection with a branch borehole, and is oriented so that when the branch casing section is lowered through the main bore, its nose will be deflected by the beveled surface of the diverter into the branch borehole. 5. Устройство по п. 2, отличающееся тем, что скошенная поверхность секции главной обсадной трубы и клинообразный элемент являются храповой парой. 5. The device according to p. 2, characterized in that the beveled surface of the section of the main casing and the wedge-shaped element are a ratchet pair. 6. Устройство по п. 2, отличающееся тем, что секция главной обсадной трубы и клинообразный элемент установлены внутри колонны обсадных труб в главной буровой скважине, и стенка указанной колонны обсадных труб имеет окно в месте пересечения с буровой скважиной ответвления. 6. The device according to p. 2, characterized in that the section of the main casing and the wedge-shaped element are installed inside the casing string in the main borehole, and the wall of the specified casing string has a window at the intersection with the branch borehole. 7. Устройство по п. 2, отличающееся тем, что внешние поверхности секции главной обсадной трубы и клинообразного элемента снабжены уплотняющим веществом. 7. The device according to claim 2, characterized in that the outer surfaces of the sections of the main casing and the wedge-shaped element are provided with a sealing substance. 8. Устройство по п. 2, отличающееся тем, что секция главной обсадной трубы и клинообразный элемент установлены внутри главной буровой скважины и поджаты друг к другу во время установки при выбранной осевой силе или продвижении. 8. The device according to p. 2, characterized in that the section of the main casing and the wedge-shaped element are installed inside the main borehole and pressed against each other during installation at a selected axial force or advancement.
