Изобретение относитс к области водоснабжени и может быть использовано дл предотвращени замерзани скважин в системах водоснабжени .The invention relates to the field of water supply and can be used to prevent freezing of wells in water supply systems.
Известен способ предотвращени замерзани скважины, в котором дл уменьщени теплопотерь водонодъемна труба имеет термоизол ционную защиту из минеральной ваты и обогреваетс соответствующим электрообогревательным прибором низкого напр жени 1.A known method of preventing freezing of a well, in which, in order to reduce heat loss, the lifting pipe has thermal insulation made of mineral wool and is heated by a suitable low voltage electrical heating device 1.
Недостатком этого способа вл етс сложность его реализации и большие расходы энергии, особенно в услови х вечной мерзлоты.The disadvantage of this method is the complexity of its implementation and the large expenditure of energy, especially in permafrost conditions.
Известен также способ предотвращени замерзани скважины, заключающийс в сливе воды из водоподъемной трубы в емкость , размещенную ниже глубины промерзани грунта 2.There is also known a method for preventing the freezing of a well, which consists in draining water from a water lifting pipe into a container located below the depth of freezing of the soil 2.
Недостатком известного способа вл етс сложность его реализации, особенно в услови х вечной мерзлоты, так как в этом случае необходимо помещать резервуар значительной емкости на большой глубине.The disadvantage of this method is the complexity of its implementation, especially in permafrost conditions, since in this case it is necessary to place a reservoir of considerable capacity at a great depth.
Цель изобретени - повышение эффективности использовани способа и упрощение его реализации в услови х вечной мерзлоты .The purpose of the invention is to increase the efficiency of using the method and simplify its implementation in permafrost conditions.
Поставленна цель достигаетс предлагаемым способом предотвращени замерзани скважины в зоне вечной мерзлоты, заключающимс в вытеснении воды из водоподъемной трубы, причем воду из водоподъемной трубы вытесн ют ниже уровн промерзани грунта путем нагнетани в нее сжатого воздуха, а затем поддерживают при помощи герметизации в водоподъемной трубе достигнутое давление, определ емое по формулеThe goal is achieved by the proposed method of preventing the well from freezing in the permafrost zone, which consists in displacing water from a water-lifting pipe, and water from the water-lifting pipe is displaced below the soil freezing level by pressurizing compressed air into it, and then supported by sealing in the water-lifting pipe determined by the formula

скважине, м.well, m
На чертеже изображен общий вид скважины , реализующей предложенный способ.The drawing shows a General view of the well that implements the proposed method.
Скважина содержит водоподъемную трубу 1, в верхней части которой установлен оголовник 2, задвижка 3, вентиль 4, манометр 5, а в нижней части - электропогружной насос 6. Задвижка 3 соединена с компрессором 7.The well contains a water-lifting pipe 1, in the upper part of which there is a head 2, a valve 3, a valve 4, a pressure gauge 5, and in the lower part an electric submersible pump 6. A valve 3 is connected to the compressor 7.
Дл предотвращени замерзани скважины в водоподъемную трубу 1, резьбовые и фланцевые соединени оголовника 2, задвижки 3, вентил 4 и манометра 5 которойTo prevent the well from freezing into the water pipe 1, the threaded and flanged connections of the head 2, valves 3, valve 4 and pressure gauge 5 of which
предварительно загерметизированы, а обратный клапан электропогружного насоса 6 вынут, нагнетают с помощью компрессора 7 сжатый воздух, вытесн наход щуюс в водоподъемной трубе 1 воду до уровн , расположенного ниже зоны вечной мерзлоты . Затем поддерживают при помощи герметизации в водоподъемной трубе достигнутое давление, определ емое по формулеpre-sealed, and the check valve of the electric submersible pump 6 is removed, the compressed air is forced through the compressor 7, and the water in the water-lifting pipe 1 is forced to a level below the permafrost zone. Then, pressure is maintained by means of sealing in a water-lifting pipe, which is determined by the formula

где Япр - глубина промерзани грунта, м; Яст - статический уровень воды в скважине, м.where Yapr - depth of soil freezing, m; Yast - static water level in the well, m
Использование предлагаемого способа предотвращени замерзани скважины по сравнению с известными способами позвол ет упростить реализацию способа предотвращени замерзани скважины при ее консервации в зоне вечной мерзлоты.Using the proposed method of preventing freezing of a well in comparison with known methods allows to simplify the implementation of the method of preventing freezing of a well during its conservation in the permafrost zone.
Предлагаемый способ позвол ет проводить кратковременную или длительную консервацию скважин в зоне вечной мерзлоты с наименьшими затратами и с полной гарантией в эксплуатации.The proposed method allows short-term or long-term preservation of wells in the permafrost zone at the lowest cost and with a full guarantee of operation.
