Description

Известные способы долива скважин промывочной жидкостью требуют посто нного наблюдени  за их осуществлением.The known methods of topping up wells with flushing fluid require constant monitoring of their implementation.

По предлагаелюму способу дл  автоматизации долива скважнны жидкостью используют соединенную с устьем скважины подвод щими трубопроводами герметичную емкость, котора  обеспечивает подачу жидкости под действием атмосферного давлени  в момент понижени  раствора в скважине.According to the proposed method for automating topping up the borehole with a liquid, a sealed container connected to the wellhead by inlet pipes is used, which ensures the delivery of fluid under the action of atmospheric pressure at the moment of lowering the solution in the well.

На чертеже показано устройство дл  долива скважины промывочной жидкостью по предлагаемому способу.The drawing shows a device for topping up the well with flushing fluid according to the proposed method.

Герметична  емкость / соединена с устьем 2 скважины двум  трубами - сливпой трубой 3 с задвил кой 4 и воздушной трубой 5. Кроме того, емкость имеет отвод 6 с задвижкой 7 дл  наполнени  ее с помощью насоса промывочной л идкостью, отвод 8 с задвижкой 9 дл  удалени  гр зи и отвод 10 с задвижкой // дл  контрол  за наполнением емкости.Sealed tank / connected to the wellhead 2 by two pipes - a drain pipe 3 with a backing 4 and an air pipe 5. In addition, the tank has a drain 6 with a slide 7 for filling it with a pump with a flushing liquid, a drain 8 with a slide 9 for removing dirt and discharge 10 with a valve / / to control the filling of the container.

При подъеме инструмента в скважине падает уровень промывочной жидкости. Когда он опуститс  ниже места соединени  воздушной трубы 5 с устьем скважины, то воздух по трубе 5 начнет поступать в емкость, а промывочна  жидкость по трубе 4 - сливатьс  в скважину. Слив будет продолжатьс  до тех пор, пока уровень жидкости в скважине не перекроет трубу 5 и прекратит доступ воздуха в емкость.When lifting the tool in the well, the level of flushing fluid drops. When it falls below the point where the air tube 5 connects with the wellhead, the air through pipe 5 will begin to flow into the tank, and the flushing fluid through pipe 4 will be drained into the well. The drain will continue until the liquid level in the well closes the pipe 5 and stops the air from entering the tank.

Объем емкости J должен быть таким, чтобы компенсировать максимально возможное падение уровн  в скважине.The capacity of tank J must be such as to compensate for the maximum possible level drop in the well.

Предмет изобретени Subject invention

Способ долива скважины промывочной жидкостью, отличающийс  тем, что, с целью автоматизации долива, исиользуют соединепнзю с устьем скважины подвод щими трубопроводами герметичную емкость, котора  обеспечивает подачу жидкости в скважину под действием атмосферного давлени  в момент понижени  раствора в скважине.The method of topping up the well with a flushing fluid, characterized in that, in order to automate the topping up, the connection to the wellhead is provided by a supply pipe sealed tank, which provides the flow of fluid into the well under the action of atmospheric pressure at the time of the decrease in the well solution.
