Description
Art
This utility model relates to a kind of oil field water well ball seat, is specifically related to a kind of well sand-blockage
Ball seat.
Background technology
At present, along with most domestic oil field development enters middle and late stage, water injection well gets more and more,
Ball seat all it is connected in separate layer water injection string bottom.The effect of ball seat is that forward seals, and reversely opens.
During long-term injecting water, the sand grains in water can sink to ball seat top, ball seat forward blow-by or
Sand setting is the most reversely not turned on, and water injection well can not normally water filling.In order to solve in water injection string
Sand grains can sink to ball seat top, then must be a kind of when water filling, and forward seals, and reversely opens, and
And the sand grains in water injection string can sink to the well sand control in the sand sediment pipe of ball seat bottom by ball seat
Stifled ball seat.
Summary of the invention
This utility model purpose is to provide one and is connected to water injection string bottom, and forward seals, instead
Sand grains in unlatching, water injection string can sink to the well in the sand sediment pipe of ball seat bottom by ball seat
Sand-blockage ball seat.
This utility model solves its technical problem and be the technical scheme is that a kind of well sand control
Stifled ball seat, mainly by lower contact, valve body, O, valve bonnet, ball seat, steel ball, spring pressure
Bar, spring, pressure cap and top connection etc. form, and lower contact is connected with valve body screw thread, valve bonnet and valve
Body is threaded, and is fixed on by ball seat between valve bonnet and valve body both ends of the surface, and steel ball is positioned at ball seat
On, spring pressure bar inner conical surface is pressed on steel ball, spring housing on spring pressure bar, pressure cap and valve bonnet
Threaded, pressure cap inner hole sleeve on spring pressure bar top, pressure cap end face pressing spring, top connection
It is connected with valve body screw thread, and by seal with O ring, in valve body, is axially arranged with sand setting passage m,
Being radially provided with backwash passage n, valve bonnet is radially provided with liquid outlet channel.
During use, this well sand-blockage ball seat bottom being connect sand setting tubing string, sand setting tubing string bottom connects
Plug seals, and well sand-blockage ball seat top is connected with water injection string.Water injection string is down to design
During position, suppressing in water injection string, well sand-blockage ball seat forward seals, it is ensured that on it
Portion's water injection packer sets.During water filling, the sand grains in water can pass through well sand-blockage ball seat valve body
Upper sand setting passage m enters sand sediment pipe.During anti-flushing well, backwash liquor passes through well sand-blockage valve with ball seat
On body, backwash passage n enters, and backwash liquor jack-up steel ball enters valve bonnet, by valve bonnet radially backwash
Passage enters water injection string, completes anti-flushing well.
The beneficial effects of the utility model are to provide one and are connected to water injection string bottom, forward
Sealing, reversely open, the sand grains in water injection string can sink to ball seat bottom sand sediment pipe by ball seat
In well sand-blockage ball seat.
