Description

Известно устройство дл  про- ведени  гидрогеологических исследований в скважинах, пробуренных в услови х вечной мерзлоты, включающее колонну зешерных трубок, нижн   часть которых закрыта стеклоы, и подъеыник. Межтрубное пространство между колонной замерных труб и стенками скважины залито незамерзающей жидкостью. A device is known for conducting hydrogeological surveys in wells drilled in permafrost conditions, including a column of grain piping, the lower part of which is covered with glass, and an elevator. The annular space between the column of measuring tubes and the walls of the well is filled with antifreeze fluid.

Однако известным устройством невозможно проводить гидрогеологические исследовани  в скважинах, в которых рассто ние от нижней зоны мерзлоты до забо  скважины меньше рассто ни  от усть  скважины до нижней зоны мерзлоты.However, it is not possible to carry out hydrogeological investigations with a known device in wells in which the distance from the lower permafrost zone to the bottom of the well is less than the distance from the wellhead to the lower permafrost zone.

Цель изобретени  - предотвращение замерзани  колонны труб в услови х вечной мерзлоты.The purpose of the invention is to prevent the freezing of the pipe string in permafrost conditions.

Дл  зтого предлагаемое устройство снабжено соединенным с подъемником поршнем, который размещен внутри колонны трубеFor this purpose, the proposed device is equipped with a piston connected to the elevator, which is placed inside the pipe

На чертеже показано предлагаеuoQ устройство.The drawing shows the proposed uQ device.

Устройство состоит из колонны замерных труб I, размещенного в них поршн  2, соединенного тросомThe device consists of a column of metering tubes I, a piston 2 placed in them, connected by a cable

5 3с подъемником А-. Верхн   часть колонны замерных труб I имеет оголовок 5 и св зана с емкостью 6, заполнен ной незамерзающей жидко стью. Емкость имеек отвод 7 с вентилем 85 3c lift A-. The upper part of the metering column I has a cap 5 and is connected to a container 6 filled with antifreeze. Capacities imeek branch 7 with the valve 8

В скважину 9 опускают колонну замерных труб I. После проведени  гидрогеологических исследований в колонну замерных труб помещают порIn the well 9, a column of metering pipes I is lowered. After hydrogeological studies have been carried out, pores are placed in the column of metering pipes.

5 щень 2. Колонну труб закрывают ого- ловком 5. По отводу 7 подают сжатый воздух, открыва  вентиль 8. Воздух вытесн ет незамерзающую жид-кость из емкости 6 в колонну замерных труб I, котора  давит на поршень 2 и гонит его в нижнюю часть замерных труб, расположенных ниже зоны мерзлоты.5 tube 2. The column of pipes is closed with the corner 5. By the outlet 7, compressed air is supplied by opening the valve 8. Air displaces non-freezing liquid from tank 6 into the column of measuring tubes I, which presses on the piston 2 and drives it to the bottom measuring pipes located below the permafrost zone.
