Description
Известно применение водо-воздушной смеси в качестве промывочной жидкости дл пр мой промывки с подачей воды с поверхности прибурении .It is known to use a water / air mixture as a washing liquid for direct washing with water supply from the surface of the surfacing.
В описываемом изобретении промывка скважины осуществл етс эрлифтом, обеспечивающим использование дл промывки забо скважины пластовой воды с уровнем, не доход щим до поверхности.In the described invention, the washing of the well is carried out by an airlift that provides for the use of formation water for flushing the bottom of the well.
На чертеже изображена схема промывки скважин посредством эрлифта.The drawing shows a diagram of the washing of wells by means of airlift.
Установка дл промывки скважины с применением эрлифта состоит из компрессора 1, от которого сжатый воздух подаетс по щлангу 2 в сальник 8 и затем-в бурильные трубы 4. На уровне грунтовых вод в колонну бурильных труб встраиваетс воздухоподающа трубка 5, верхний конец которой располагаетс на уровне грунтовых вод. При подаче под давлением воздуха по внутренней трубке эрлифта по межтрубному пространству 6 происходит подъем аэризованной жидкости с выкидом ее в скважину на уровне грунтовых вод. Дл улавливани щлама применена щламова труба 7, установленна выще колонковой трубы 8.The installation for flushing the well using airlift consists of compressor 1, from which compressed air is fed through hose 2 into the gland 8 and then into the drill pipe 4. At the groundwater level, an air supply tube 5 is built into the drill pipe string groundwater. When applying air pressure through the inner tube of the airlift through the annular space 6, the aerated fluid is lifted and discarded into the well at the groundwater level. A slime pipe 7 was used to trap the slime, installed above the core pipe 8.
Конструкци эрлифта в предлагаемом исполнении обеспечив(.:гг обратную циркул цию жидкости на забое с выносом пульпы в шлампуловитель и исключает подачу воды в скважину с поверхности.The proposed airlift design provided (.: Yy the reverse circulation of fluid at the bottom with removal of slurry into the separator and eliminates the flow of water into the well from the surface.
