Description
В процессе бурени скважин возникает необходимость удерживать цементный раствор от проникновени в нижнюю часть скважины. Дл этой цели используют пробки, которые продвигают по стволу скважины к месту их установки с помощью специальных устройств.During the drilling of wells, it becomes necessary to keep the cement slurry from penetrating into the lower part of the well. For this purpose, plugs are used that move the wellbore to the place of their installation using special devices.
Предлагаемое устройство защищает резиновые манжеты от возможной порчи при проталкивании пробки вдоль ствола скважины. Это достигаетс тем, что оно выполнено в виде прикрепленного к нижнему концу труб цилиндра, внутрь которого помещена пробка, выталкиваема в ствол скважины струей жидкости, нагнетаемой с поверхности насосом .The proposed device protects the rubber cuff from possible damage when pushing the plug along the wellbore. This is achieved by the fact that it is made in the form of a cylinder attached to the lower end of the pipes, into which the cork is inserted, is pushed into the well bore by a jet of fluid pumped from the surface by a pump.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
На конец бурильных труб наворачиваетс верхн часть корпуса турбобура 1, а во внутреннюю часть помещаетс специальна пробка 2, корпус которой изготовл етс из дерева и имеет сквозное отверстие 5, два резиновых манжета 4 и резиновый клапан 5.The upper part of the casing of the turbo-drill 1 is screwed onto the end of the drill pipes, and a special plug 2 is placed into the interior, the casing of which is made of wood and has a through hole 5, two rubber cuff 4 and a rubber valve 5.
При спуске такого устройства жидкость из скважины проникает в трубы через клапан 5. После спуска пробки на требуемую глубину производ т закачку жидкости в трубы; при этом клапан 5 закрываетс , струей жидкости пробка выталкиваетс в ствол скважины и застревает там за счет большего диаметра резиновых манжет 4.When such a device is lowered, fluid from the well penetrates the pipes through valve 5. After the plug is lowered to the required depth, fluid is pumped into the pipes; in this case, the valve 5 is closed, the tube is pushed out into the wellbore by a jet of liquid and stuck there due to the larger diameter of the rubber cuffs 4.
Устройство дл доставки пробки к месту ее установки при цементажных работах в скважине, отличающеес тем, что, с целью защиты резиновых манжет от возможной порчи при проталкивании ее вдоль ствола скважины, оно выполнено в виде прикрепленного к нижнему концу труб цилиндра, внутрь которого помещена пробка, а выталкивание последней в ствол скважины производитс струей жидкости, нагнетаемой с поверхности насосом.A device for delivering a stopper to its installation site during cementing operations in a well, characterized in that, in order to protect the rubber cups from possible damage when pushing it along the wellbore, it is designed as a cylinder attached to the lower end of the pipes, and pushing the latter into the wellbore is produced by a jet of fluid pumped from the surface by a pump.
