Description
Дл борьбы с уходод промывочио ЖИДКОСТИ В зону поглощени, при турбинно-роторном бурении скважин, нрнмен ютс paзлив rыe быстросхватывающиес смеси высокой в зкости. Эти смеси заполн ют зону поглощени и преграждают уход промывочной жидкости. Чтобы избежать ухода быстрозахватывающейс смеси и возможности удержат , се, В начале зоны поглои1сни предлагаетс исиользовать вление вакуума дл заме.п, продвижени столба цементного раствора В зону пог.тощени .To combat flushing fluid, turbo-rotary drilling of wells is absorbed into the absorption zone by mixing high-viscosity mixtures. These mixtures fill the absorption zone and stop the washing liquid from escaping. In order to avoid the withdrawal of the quick-setting mixture and the possibility of retaining it, ce, At the beginning of the zone of absorption, it is proposed to use the phenomenon of vacuum to replace the advance of the column of cement slurry Into the area of the accumulated sludge.
Способ состоит В следующем. Перед началом бурени в устье шахтового направлени бетонируетс на 5-6 м обсадна труба диамет К )м 16-18 заканчиваюгиа с вверху муфтой.The method consists in the following. Before starting drilling, the casing pipe of diameter K) m 16-18 with a coupling at the top is concreted for 5-6 m at the mouth of the mine direction.
При по вленш поглощени во вре-м бурени скважины уровень промывочной жидкости упадет. Производитс подсчет необходимого количества цементного раствора дл заполнени зоны поглощени .When absorption occurs during drilling, the level of flushing fluid will drop. The required amount of cement slurry is calculated to fill the absorption zone.
Через заливочную головку, установленную на муфте обсадной трубы , закачиваетс необходимое количество п,емент1 ого раствора с 40-50°о консистениией цемента.Through the filling head installed on the casing coupling, the required amount of n, cement solution is pumped from 40-50 ° about the consistencies of the cement.
Заливочна головка, краны и места соединений должны быть проверены на герметичность.The filler head, taps and connections must be leak tested.
После п юкачки цемента, закрываютс краны как на головке, так и па за. ивочном агрегате.After pumping the cement, the taps are closed both on the head and the pas. spring assembly.
Закаченный в скважину цемент будет удерживатье под заливочпой ГОЛОВКОЙ за счет образовавщегос вакуума, который образуетс пои передв11жении в скважине цементного столба.The cement pumped into the well will be held under the filling head due to the resulting vacuum, which is formed by penetration into the cement column in the well.
