Description
(54) СПОСОБ ИЗОЛЯЦИИ ВОД(54) METHOD OF WATER INSULATION
1one
Изобретение относитс к бурению и эксплуатации скважин.The invention relates to the drilling and operation of wells.
Известен способ изол ции вод путем закачки тампонажного раствора через отверсти в обсадной колонне с использованием пакеров 1.There is a method for isolating water by injecting a cement slurry through openings in the casing using packers 1.
Недостатком способа вл етс низка надежность изол ции из-за смыкани трещин породы в прискважинной области при установке пакера, которые не заполн ютс тампонажным раствором и восстанавливаютс при сн тии пакера.The disadvantage of this method is the low reliability of the insulation due to closure of rock cracks in the near-wellbore area when installing the packer, which are not filled with cement slurry and are restored when the packer is removed.
Наиболее близким к изобретению вл етс способ изол ции вод в нефт ных и газовых скважинах путем закачки тампонажного раствора затрубное пространство обсадной колонны с каналами через заливочные трубы, спускаемые до предполагаемой подошвы моста, возводимого в обсадной колонне , и извлекаемые до кровли моста с последуюш .им вымывом излишков тампонажного раствора обратной промывкой 2.The closest to the invention is a method of isolating water in oil and gas wells by pumping cement slurry into the annular space of the casing with channels through the filling pipes, which are lowered to the intended base of the bridge, erected in the casing, and extracted to the roof of the bridge with subsequent leaching of excess cement slurry backwash 2.
Недостатком известного способа вл етс низка надежность изол ции из-за возможности восстановлени каналов циркул ции в затрубном пространстве скважины.A disadvantage of the known method is the low reliability of the insulation due to the possibility of restoring circulation channels in the annulus of the well.
Цель изобретени - повышение надежности изол ции водопровод щих трещин ниже эксплуатационного фильтра за счет использовани сил распора колонны с установленным в ней мостом.The purpose of the invention is to increase the reliability of isolating water-conducting cracks below the production filter by using the expansion force of a column with a bridge installed in it.
Поставленна цель достигаетс тем, что обратную промывку осуществл ют при давлении не менее давлени закачки тампонажного раствора. После чего давление выдерживают в течение времени затвердевани тампонажного раствора.This goal is achieved by the fact that the backwash is carried out at a pressure of not less than the injection pressure of the cement slurry. After that, the pressure is maintained during the hardening time of the cement slurry.
Способ изол ции вод осуществл ют следующим образом.The method of isolating the water is carried out as follows.
