Description

Известны устройства дл  автоматической остановки скважины При порыве выкидной линии, состо щие из двухступенчатого цилиндра с перегородками , отверсти ми дл  выхода жидкости и дифференциального поршн  с отверсти ми дл  перетока жидкости.Apparatus for automatically shutting down a well-known device. In a flush of a flow line, consisting of a two-stage cylinder with partitions, fluid outlet openings and a differential piston with fluid flow openings.

Описываемое устройство отличаетс  от известных тем, что в поршень вмонтирован штуцер, который извлекаетс  дл  замены через окна в цилиндре и поршне, -совмещаемые при остановке скважины. Это облегчает обслуживание Скважины.The described device differs from the known ones in that a nozzle is mounted in the piston, which is removed for replacement through the windows in the cylinder and the piston, which are displaced when the well is stopped. This facilitates well maintenance.

На чертеже изображено устройство.The drawing shows the device.

Устройство выполнено из двухступенчатого цилиндра / с двум  перегородками , втулками 2 с отверсти м1И А дл  выхода жидкости, двухступенчатого дифференциального поршн  3 с отверсти ми 5 и В дл  перетока жидкости и штуцера 4, укрепленного в поршне.The device is made of a two-stage cylinder / with two partitions, sleeves 2 with holes m1I A for liquid outlet, two-stage differential piston 3 with holes 5 and B for flow of liquid and fitting 4 fixed in the piston.

Устройство устанавливаетс  на струне манифольда вместо штуцерного патрубка и работает следующим образом.The device is mounted on a manifold string instead of a choke pipe and operates as follows.

Нефть, выход  из арматуры, поступает через отверсти  Б в поршень 3, затем через штуцер 4 и выходные отверсти  В поступает в выкидную линию 5.Oil, the outlet of the valve, flows through the holes B into the piston 3, then through the fitting 4 and the outlets B comes into the flow line 5.

При поломке выкидной линии или при разр дке струны, во врем  смены штуцера, заштуцерное давление падает. Тогда усилие, действующее на плунжер до штуцера, преобладает над усилием, действующим на поршень после щтуцера, и под действием перепада-усилий поршень 3 движетс  в крайне левое положение.When the flow line breaks or when the string is discharged, during the change of fitting, the nozzle pressure drops. Then the force acting on the plunger up to the choke, prevails over the force acting on the piston after the piston, and under the action of the differential force the piston 3 moves to the far left position.

Нри таком положении поршн  выходные отверсти  Б перекрываютс  стенками цилиндра / и доступ нефти из скважины прекращаетс .In such a position of the piston, the outlet openings B are blocked by the walls of the cylinder (i) and the access of oil from the well is stopped.
