Description
(54) СПОСОБ ИЗВЛЕЧЕНИЯ ФИЛЬТРОВ ИЗ СКВАЖИН(54) METHOD OF EXTRACTING FILTERS FROM WELLS
Изобретение относитс к буровой технике и может быть использовано при замене фильтровых колонн вод ных и технологических скважин подземного выщелачивани .The invention relates to a drilling technique and can be used when replacing filter columns of water and process wells of an underground leach.
Известен способ извлечени труб и фильтров из скважин, включающий подъем их гидродомкратами с лебедкой и одновременную подачу раствора под давлением в полость поднимаемой колонны труб 1.There is a known method for extracting pipes and filters from wells, including lifting them with hydraulic jacks with a winch and simultaneously supplying the solution under pressure into the cavity of the lifting string of pipes 1.
Недостатком известного способа вл етс то, что при подъеме фильтров из-за плотного бокового.обжати фильтра породой затрачиваютс большие усили . Дл этого требуютс т говые средства большой грузоподъемности (лебедки, дс краты и т. п.), что повышает стоимость работ при извлечении фильтров и зачастую приводит к их повреждени м.The disadvantage of this method is that when lifting the filters due to the dense lateral compression of the filter, large forces are expended. This requires heavy-duty traction facilities (winches, ds crates, etc.), which increases the cost of work when extracting filters and often leads to damage to them.
Наиболее близким к описываемому изобретению по технической сущности вл етс способ извлечени фильтров из скважин путем подъема их с применением т говых средств (лебедок, буровых станков, домкратов) и одновременным воздействием на них вибрационнь 1х нагрузок 2J.The closest to the described invention to the technical essence is a method of extracting filters from wells by lifting them with the use of traction means (winches, drilling rigs, jacks) and the simultaneous action on them of vibration 1x loads 2J.
Недостаток способа заключаетс в том, что при воздействии вибрации на фильтровую колонну обжимающий ее грунт находитс на месте с некоторым перераспределением частиц грунта, однако усилие обжати от бокового давлени остаетс неизменным. При этом недостаточно снижаютс усили подъема фильтра из скважин.The disadvantage of the method lies in the fact that when a filter is subjected to vibration on the filter column, the soil is compressed in place with a certain redistribution of soil particles, however, the lateral pressure reduction force remains unchanged. At the same time, the filter lifting forces are not sufficiently reduced.

Цель изобретени - снижение усилий , затрачиваемых при извлечении фильтров.The purpose of the invention is to reduce the effort involved in removing the filters.
Поставленна цель достигаетс тем, что перед подъемом под фильтром The goal is achieved by the fact that before climbing under the filter
5 образуют полость.5 form a cavity.
Способ заключаетс в следующемThe method is as follows.
