Description
Известны устройства дл магнитных измерений рассто ний между параллельными буровыми скважинами, состо щие из секции бурового става и феррозонда.Arrangements for magnetic measurements of the distance between parallel boreholes are known, consisting of a section of a drill rod and a fluxgate.
Предлагаемое устройство отличаетс от известных тем, что секци бурового става выполнена с немагнитной вставкой, а феррозонд размещен в месте разрыва ферромагнитных частей секции. Это позвол ет повысить точность измерений.The proposed device differs from the known ones in that the section of the drill rod is made with a non-magnetic insert, and the ferro probe is placed at the point of rupture of the ferromagnetic parts of the section. This allows for improved measurement accuracy.
На чертеже показано описываемое устройство .The drawing shows the described device.
Секци / бурового става разделена немагнитной вставкой 2, на которой закреплен корпус 3 из немагнитного материала с феррозондом 4.Section / drill rod is divided non-magnetic insert 2, on which is fixed the housing 3 of non-magnetic material with a ferro probe 4.
Устройство работает следующим образом.The device works as follows.
Бурова секци 1 с немагнитной вставкой 2 и феррозондом 4 устанавливаютс на буровойA drill section 1 with a non-magnetic insert 2 and a flux probe 4 is mounted on the drilling rig.
машине, представл ющей собой магнитопровод . При работе по ранее пробуренной скважине перемещаетс посто нный магнит. По величине напр женности магнитного пол этого магнита, измеренной феррозондом, определ етс рассто ние между пробуренной и вновь проходимой скважинами.machine, which is a magnetic circuit. When operating on a previously drilled well, a permanent magnet is moved. The magnitude of the magnetic field of this magnet, measured by a flux probe, determines the distance between the drilled and newly traversed wells.
