Abstract
The utility model relates to a bottom part antislag water distribution apparatus belonging to a part of oil production mechanism. An upper tie-in 1 is connected with an outer pipe 3 by a screw thread, a water faucet 2 is spliced with a water injection body 4, a spring 5 and a flushing valve 6 are arranged inside the water injection body 4, a block closure of the anti-slip 7 is spliced with the flushing valve, an inner pipe 8 is connected with the water injection body 4 and a lower tie-in 9 by a screw thread, the lower tie-in 9 is connected with the outer pipe 3 by a screw thread. The utility model has the advantages of novel structure, sand-protecting function without leakage of valve, safe and reliable water injection, making the oil production on the rails.
Description
Technical field the utility model belongs to the parts of oil exploitation machinery.
When background technology is recovered the oil in the oil field, when the needs water filling, the not sand prevention of using of injection well downhole flow regulator now, its shortcoming is that silt can pad up the valve in the well, causes the valve leakage, influences water filling, thereby has influence on normally carrying out of production.
Summary of the invention the utility model provides a kind of bottom to prevent the slag injection well downhole flow regulator, to solve the problem of not sand prevention of present injection well downhole flow regulator.The technical scheme that this practicality is adopted is: top connection 1 is threaded with outer tube 3, water nozzle 2 and water filling body 4 are pegged graft, spring 5 is positioned at this water filling body, flushing valve 6 is positioned at this water filling body, anti-seat envelope gliding mass 7 is pegged graft with this flushing valve, in pipe 8 be threaded with water filling body 4, manage in this and be threaded with lower contact 9, lower contact 9 is threaded with outer tube 3.During use, water enters from top connection, through water filling body, anti-seat envelope gliding mass, and pipe and lower contact in entering, sand then falls between outer tube and interior pipe, can not fall into the shaft bottom.
Advantage of the present utility model is: novel structure, have the function of sand prevention, and can not make the valve leakage, guarantee that water filling is safe and reliable, oil extraction operation is normally carried out.
Appended drawings is the utility model structural representation.
