Description
Technical field
This utility model is a kind of wellhead equipment used for water injection wells in oil fields, is that a kind of well filters ball-and-seat.
Background technology
As the water injection well strata pressure having is high, when water injection well stops note for some reason, the injection water being injected in stratum will
Return and tell in Hui Jing, and with waterflood-transmission line earthward waterflood-transmission line backflow, water filling layer tells that flow in process is big returning, and flow velocity is fast, ground
Layer produces exciting, is easily carried out reservoir sand, causes sand to bury water injection string, be allowed to can not water filling again, stratum water injection rate
Reduce, affect well oil output.Due to can not water filling again, be forced operation well workover, increase operating cost.After sand card tubing string,
There is also during operation well workover and can not smoothly play out tubing string, the heavy repair task carried out by high cost, economic loss are huge.To solve
This problem, technical staff have developed well head of the ball-and-seat installed in water injection well so as to can stop that stratum water returns to ground.
Such as Chinese patent 200420107009.4《Water injection well mouth check valve》, when making water injection well stop note for some reason, it is injected in stratum
Injection water can not be returned to be told in Hui Jing, it is to avoid water injection well shakes out.But this ball-and-seat single function, changes valve seat inconvenience, does not have
Filter the function of injection water, it is impossible to stop that mechanical admixture enters stratum, therefore, its performance is poor, it is impossible to fully meet note
The requirement of well.
The content of the invention
The purpose of this utility model is that a kind of well of design filters ball-and-seat, when making water injection well stop note for some reason, is injected into ground
Injection water in layer can not be returned and be told in Hui Jing, it is to avoid water injection well shakes out, it is ensured that water injection well is smoothly driven a well water filling again.
What the purpose of this utility model was realized in：Including water supply connector, valve ball frame, water out adapter, valve ball, valve seat,
UNICOM's plate, outer filter tube, middle filter tube, interior filter tube, valve body, shrouding, plug, the upper weld water out adapter of valve body, valve ball
It is placed in valve ball frame, valve seat is connected with the bottom of valve ball frame, aperture of the valve ball with diameter greater than valve seat, valve ball are seated in valve seat
On the valve port of upper end and fitted seal, on valve ball frame, have a communication groove, valve ball it is rack-mounted enter valve body in, the top of valve ball frame is upper with valve body
Portion is threadedly coupled, and the lower surface of valve seat is sitting in the inner circular bead of valve body, and valve seat is under water out adapter, described communication groove
By the inside of valve ball frame and water out adapter UNICOM, outer filter tube, middle filter tube, interior filter tube are set in together rear its top and connection
The connection of logical plate, the annular space between outer filter tube and middle filter tube are communicated with the linked hole on UNICOM plate, the endoporus of interior filter tube and
Linked hole on UNICOM's plate is communicated, and has filtration seam, outer filter tube and middle filter tube on outer filter tube, middle filter tube, interior filter tube
Between the bottom of annular space closed by shrouding, the top of plug is inserted in the bottom of interior filter tube, and plug is connected with valve body lower portion screw thread
Connect, by UNICOM's top of the plate in the inner circular bead of valve body, in the lower weld water supply connector of valve body, water supply connector in UNICOM's plate it
Under, the water flowed into from water supply connector can only flow to water out adapter by the gap of outer filter tube, middle filter tube, interior filter tube.
The beneficial effects of the utility model are：After water injection well stops note for some reason, valve ball falls, and prevents stratum water from returning to ground
Waterflood-transmission line, stratum will not produce excitement, will not shake out, and smoothly can drive a well after stopping note water filling again, it is to avoid water injection well stops for some reason
Economic loss is produced after note.Injection water will could inject ground behind the gap on outer filter tube, middle filter tube, interior filter tube
Layer, injection water are filtered, and can stop that debris enter stratum, and stratum can be prevented to be blocked, and valve ball frame can after pulling down from valve body
Valve ball, valve seat are taken out maintenance, changed, outer filter tube, middle filter tube, interior filter tube sleeve type are installed and can increase flow-passing surface
Product, reduces liquid flowing resistance, the debris being blocked can be cleared up after pulling down plug 14, therefore, practicality of the present utility model is good.
