Description

Известные устройства дл  цементной заливки скважин обладают тем недостатком, что при удалении лишнего цемента из скважины возможно попадание промывочной жидкости под клапан на обсадной колонне и тем самым ухудшАК« качества заливки.The prior art cement pouring devices have the disadvantage that when removing excess cement from the well, flushing fluid can get under the valve on the casing and thereby deteriorate the quality of casting.

Предлагаемое устройство не имеет этого недостатка, так как оно выполнено в виде наконечника с резиновой шайбой и шаром, И1меющим диаметр больший, чем диаметр отверсти  в резиновой шайбе и помещаемым над ней.The proposed device does not have this disadvantage, since it is made in the form of a tip with a rubber washer and a ball, which has a diameter larger than the diameter of the hole in the rubber washer and placed above it.

На фиг. 1 показана схема устройства, спущенного в скважину; на фиг. 2 - наконечник и клапан в разрезе.FIG. 1 shows a diagram of a device launched into a well; in fig. 2 - a tip and the valve in a section.

На нижний копец труб / навинчен наконечник 2 с резиновы.ми шайбами 3, на которых покоитс  шар, диаметр которого больше, чем диаметр отверсти  в резиновых шайбах. Седло клапана 4 на колонне 5 с верхней стороны выполнено конусным, и шар, помещенный на этот конус , полностью перекрывает проходное отверстие и предотвраш.ает возможность перетока жидкости под клапан.At the lower end of the pipes / tip 2 is screwed with rubber washers 3, on which a ball with a diameter larger than the diameter of the hole in the rubber washers rests. The valve seat 4 on the column 5 is conical on the upper side, and the ball placed on this cone completely blocks the bore and prevents the flow of fluid under the valve.

Нри работе с устройством скважину промывают водой, затем закрывают задвижку на трубах и в затрубное пространство закачивают цементный раствор, который продавливают расчетным количеством воды, причем во избежание попадани  воды к башмаку колонны, ее объем следует yjMeHb HTb на 0,5-1 м против расчетного. В конце этого ni)oцесса межтрубное пространство от обратного клапана до 40 м по высоте останетс  заполненным цементным раствором, который нужно удалить из скважины. Дл  этого в трубах насосом создают давление и тем самым продавливают шар сквозь резиновые шайбы так, чтобы он упал на седло обратного клапана, после чего промывают скважину, удал   цемент из колонны.When working with the device, the well is rinsed with water, then the valve is closed on the pipes and cement solution is pumped into the annulus, which is forced with the calculated amount of water, and to avoid the water getting into the column shoe, its volume follows yjMeHb HTb by 0.5-1 m against the calculated . At the end of this ni) process, the annular space from the check valve to 40 m in height will remain filled with cement mortar, which must be removed from the well. To do this, the pipes are pressurized with a pump and thereby force the ball through the rubber washers so that it falls on the check valve seat, and then flushes the well, removing the cement from the column.
