Description
Изобретение относитс к области изол ции водоносных горизонтов в скважинах н, в частности, к способу целентажа скважин малого диаметра .The invention relates to the field of isolating aquifers in wells and, in particular, to a method of targeting small-diameter wells.
Известные способы цементажа скважин малого диаметра не обеспечивают достаточную прочность цементного кольца из-за .малого зазора между стенками скважины и обсадной колонной.Known methods for cementing small-diameter wells do not provide sufficient strength for the cement ring due to the small gap between the walls of the well and the casing.
В описываемом способе этот недостаюк устранен тем, что зазор .между стенками скважины и обсадной колонной увеличиваетс за счет образовагш каверн но высоте цементируемого участка скважины, производимых последовательным или одновременным взрывом торпед .In the described method, this shortage is eliminated by the fact that the gap between the walls of the well and the casing string is increased due to the formation of cavities but the height of the cemented portion of the well produced by a sequential or simultaneous explosion of torpedoes.

способа н)оизводитс следующим образом: вьнне продуктивной части разреза подрывают п ть-семь торпед с рассто ни .ми между отдельными торнедами в 3-4 м.Method n) is carried out as follows: in the productive part of the section, five to seven torpedoes are undermined with spacing between separate turntables of 3-4 m.
В результате торпедировани в стенках екважины образуютс каверны , днаметр и высота которых завис т от диаметра и длины торпеды . Проведенные исследовани показали, что при подрыве второй торпеды длиной в 1 м в и.тотно.м песча 1ике образуетс каверна дна .метро.м около 400 мм и высотой свьнне 1 м.As a result of torpedoing, cavities are formed in the walls of the wellbore, the meter and the height of which depend on the diameter and length of the torpedo. Studies have shown that when a second torpedo is blown up with a length of 1 m, and a total of about 400 mm and a height of 1 m is formed, a cavern of the bottom of a meter is formed.
После указанного торпедировани скважина прорабатываетс , промываетс н производитс спуск колонны с кюледующпм дементажем .After the indicated torpedoing, the well is being worked, washed and the column is being descended with further dementage.
В образованных таким способо.м кавернах мондпость цементного кольца резко возрастает, и создаготс благопри тные услови д.п падежного нсрекрытн водоносных пластов.In the cavities formed by such a method, the mondness of the cement ring rises sharply, and favorable conditions are created for the case of undiscovered aquifers.
