(54) СПОСОБ КРЕПЛЕНИЯ СТЕНОК СКВАЖИНЫ(54) METHOD OF FIXING WALLS WALLS

1one

Изобретение относитс  к горному делу, а именно к креплению стенок скважин обсадными трубами.FIELD OF THE INVENTION The invention relates to mining, namely to fastening the walls of wells with casing.

Известен способ креплени  стенок скважины обсадной трубой, выполненной из тонкой металлической ленты 1.There is a known method of fixing the walls of a well by a casing made of thin metal strip 1.

Недостаток этого способа заключаетс  в том, что дл  его осуществлени  требуетс  дополнительное оборудование дл  образовани  из ленты обсадной трубы.The disadvantage of this method is that it requires additional equipment to form a casing tape.

Известен также способ креплени  стенок скважины обсадной трубой, выполненной в виде уложенной по спирали металлической ленты, близлежащие слои которой располагают внахлест, при этом сама лента состоит из отдельных, расположенных по диагонали, секторов, шарнирно св занных по коротким сторонам, а по длинным сторонам укреплены ребра жесткости 2.There is also known a method of fastening the borehole walls with a casing pipe made in the form of a spirally laid metal tape, the adjacent layers of which are overlapped, while the tape itself consists of separate diagonally-shaped sectors hinged on the short sides and reinforced along the long sides stiffeners 2.

Недостаток известного способа заключаетс  в том, что крепление стенок скважин осуществл етс  обсадной трубой, выполненной последовательным наращив-анием отдельных секций, что требует затрат на изготовление каждой отдельной секции и их сборку.A disadvantage of the known method is that the casing of the boreholes is carried out by a casing pipe made by successively increasing individual sections, which requires the cost of manufacturing each individual section and assembling them.

Цель изобретени  - снижение затрат на строительство скважины за счет уменьшени  расходов на обсадную трубу.The purpose of the invention is to reduce the costs of well construction by reducing the costs of the casing.

Поставленна  цель достигаетс  тем, что согласно способу обсадную трубу образуютThe goal is achieved by the method of forming a casing according to the method.

5 путем спуска в скважину уложенной в рулон металлической ленты, наружный конец которой закрепл ют на забое, а внутренний вращают в направлении, противоположном навивке ленты с одновременным осевым5 by lowering into a well a metal tape laid in a roll, the outer end of which is fixed to the bottom, and the inner one is rotated in the direction opposite to the winding of the tape with simultaneous axial

Кроме того, рулон может быть спущен в скважину частично развернутым в аксиальном направлении, причем диаметр его при этом меньше диаметра скважины.In addition, the roll may be lowered into the well partially deployed in the axial direction, and its diameter is less than the diameter of the well.

Способ осуществл етс  следующим об15 разом.The method is carried out as follows.

Металлическую ленту, предварительно уложенную в рулон, опускают на забой скважины , при этом наружный конец ленты отгибают от рулона под пр мым углом и зак2Q репл ют на забое вдавливанием в грунт. Затем внутренний конец ленты рулона вращают в направлении, противоположном навивке ленты с одновременным осевым перемещением его от забо . При этом происходит выт гивание рулона в длину и расширение витков рулона до стенок скважины . При этом металлическа  лента укладываетс  по спирали в трубу, а дл  образовани  прочной трубы, не допускающей дренирование воды, близлежащие слои металлической ленты располагают внахлест. Наружный конец ленты, который выходит на устье скважины, закрепл ют аналогично внутреннему, вдавлива  в грунт отогнутый конец ленты. Металлическую ленту, уложенную в рулон , предварительно перед спуском в скважину можно частично развернуть в аксиальном направлении, причем диаметр этого рулона также как и предыд ущего должен быть меньше диаметра скважины. Технико-экономическа  эффективность предлагаемого способа заключаетс  в ускоренном строительстве скважин и уменьшении св занных с ним расходов. Формула изобретени  1. Способ креплени  стенок скважины обсадной трубой, выполненной в виде уложенной по спирали металлической ленты, близлежащие слои которой располагают внахлест, отличающийс  тем, что, с целью снижени  затрат на строительство скважины за счет уменьшени  расходов на обсадную трубу, последнюю образуют путем спуска в скважину уложенной в рулон металлической ленты, наружный конец которой закрепл ют на забое, а внутренний вращают в направлении , противоположном навивке ленты с одновременным осевым перемещением его от забо . 2. Способ по п. 1, отличающийс  тем, что рулон спускают в скважину частично развернутым в аксиальном направлении, причем диаметр его меньше диаметра скважины . Источники информации, прин тые во внимание при экспертизе 1, Патент ФРГ № 118492, кл. 5 а 17/00, опублик. 1956.The metal tape, previously laid into a roll, is lowered to the bottom of the well, while the outer end of the tape is bent away from the roll at a right angle and closed on the bottom by pressing it into the ground. Then the inner end of the tape roll is rotated in the direction opposite to the winding of the tape with simultaneous axial movement from the bottom. When this occurs, the roll is pulled out in length and the roll turns expand to the borehole walls. In doing so, the metal tape is laid in a spiral in the pipe, and to form a strong pipe that prevents water from draining, the adjacent layers of the metal tape are overlapped. The outer end of the tape, which extends to the wellhead, is secured in a manner similar to the inner one, having pressed the bent end of the tape into the ground. The metal tape laid in a roll can be partially deployed in the axial direction before being lowered into the well, and the diameter of this roll as well as the previous grip should be smaller than the diameter of the well. The technical and economic efficiency of the proposed method consists in accelerated well construction and reduction of associated costs. Claim 1. The method of attaching the walls of a well with a casing pipe made in the form of a spiral-laid metal strip, the adjacent layers of which have an overlap, characterized in that, in order to reduce the cost of building a well by reducing the costs of the casing, into the well of a metal tape laid in a roll, the outer end of which is fixed on the bottom, and the inner end is rotated in the direction opposite to the winding of the tape with simultaneous axial movement from bo 2. A method according to claim 1, characterized in that the coil is lowered into the well partially deployed in the axial direction, and its diameter is less than the diameter of the well.
