Abstract

Фильтр скважины состоит из множества последовательно соединенных элементов, каждый из которых имеет цилиндрическую соединительную секцию по крайней мере на одном своем направлении фильтра, расположенных вокруг другой секции фильтра через заранее заданный интервал в периферическом направлении фильтра, и проволоку, намотанную на внешней периферии поддерживающих реек так, что образуются щели заданной ширины. Фильтр скважины дополнительно включает средство выравнивания наружного диаметра, расположенное вокруг соседних соединительных секций двух элементов фильтра, соединенных друг с другом, по существу для выравнивания внешнего диаметра соединительных секций с внешним диаметром других секций.

  1. Фильтр скважины состоит из множества последовательно соединенных элементов, каждый из которых имеет цилиндрическую соединительную секцию по крайней мере на одном своем направлении фильтра, расположенных вокруг другой секции фильтра через заранее заданный интервал в периферическом направлении фильтра, и проволоку, намотанную на внешней периферии поддерживающих реек так, что образуются щели заданной ширины. Фильтр скважины дополнительно включает средство выравнивания наружного диаметра, расположенное вокруг соседних соединительных секций двух элементов фильтра, соединенных друг с другом, по существу для выравнивания внешнего диаметра соединительных секций с внешним диаметром других секций.
