Abstract
The utility model relates to a hollow water distributor allowing a pressure test. An upper joint is connected with the upper part of an inner pipe, a core is arranged inside the inner pipe, the lower part of the inner pipe is connected with a lower joint, a spring and a sliding valve are sleeved outside the inner pipe, the sliding valve is positioned below the spring, the spring is positioned above the upper joint, a valve base is arranged below the sliding valve, a sliding valve base is arranged above the valve base, the lower part of the valve base is sleeved outside the upper part of the lower joint, a communication hole is formed on the lower joint, a seal sleeve is sleeved outside the lower joint, covers the communication hole of the lower joint and is fixed on the lower joint via a pin, the lower part of the valve base is arranged on the seal sleeve, a lock ring is sleeved on the lower joint, and a lock ring groove is arranged on the inner wall of the lower part of the valve base. The diameter of the upper part of the inner wall of the valve base is larger than that of the lower part of the inner wall of the valve base, resulting in a hollow cavity between the valve base and the lower joint. A water nozzle is arranged on the core, and during pressure test of a water injection string, the sliding valve and the valve base are kept in the original state and a water injection hole on the inner pipe is plugged to seal the water injection string. The hollow water distributor can realize pressure test and water injection of the water injection string without running or catching the core.
Description
One, technical field
The utility model is the laminated distributor under well water filling instrument that oil-field flooding is used, and is a kind of hollow distributor capable of testing pressure.
Two, background technology
Existing hollow distributor will be lowered to the fuse of no water nozzle, makes hollow distributor be in air-tight state, can be to the water injection string pressure testing, guarantee that water injection string sealing do not miss, the fuse that will not have a water nozzle with the salvaging car again after try to press is pulled out, and input is with the fuse of water nozzle to carry out water filling again, owing to need drag for the throwing fuse, therefore, operation is many, and workload is big, engineering time is long, the fuse that drops into is not easy sealing, causes the water injection well cisco unity malfunction, influences oil field development.
Three, summary of the invention
The purpose of this utility model provides a kind of hollow distributor capable of testing pressure, and making it not need to drag for the throwing fuse just can be to water injection string pressure testing and water filling.
The purpose of this utility model has been achieved in that top connection, spring, interior pipe, fuse, top connection connects with interior pipe top, fuse is in interior pipe, interior pipe bottom connects with lower contact, spring, outside the pipe, slide-valve was under the spring in slide-valve was sleeved on, and spring is under the top connection, it under the slide-valve valve seat, the slip valve seat is on valve seat, and the valve seat bottom is sleeved on outside the lower contact top, and linked hole is arranged in the lower contact, sealing shroud is sleeved on outside the lower contact, sealing shroud covers the linked hole in the lower contact, and in lower contact, the valve seat lower seat is on sealing shroud by dowel fixes for sealing shroud, lock ring is sleeved in the lower contact, and the valve seat lower inner wall has the lock ring groove.
The valve base inner wall upper diameter is greater than lower diameter, and making between valve seat and the lower contact has cavity.
Water nozzle is arranged on the fuse.
The beneficial effects of the utility model are: during to the water injection string pressure testing, slide-valve, valve seat are motionless, the water injection hole in sealing on the pipe, make water injection string be in air-tight state, can realize the pressure testing to water injection string, not needing to drag for the throwing fuse just can be to water injection string pressure testing and water filling, therefore, use this novel, operation is few, and workload is little, engineering time is short, do not need to drop into fuse, normally water filling of water injection well has remarkable economic efficiency.
Four, description of drawings
Accompanying drawing is a structure assembling drawing of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Form by top connection 1, spring 2, interior pipe 3, slide-valve 4, valve seat 5, fuse 6, lock ring 7, pin 8, sealing shroud 9, top connection 10.Top connection 1 connects with interior pipe 3 tops, fuse 6 is in interior pipe 3, interior pipe 3 bottoms connect with lower contact 10, spring 2, manage outside 3 in slide-valve 4 is sleeved on, slide-valve 4 is under the spring 2, spring 2 is under the top connection 10, is valve seat 5 under the slide-valve 4, and 4 of slide-valves are on valve seat 5, valve seat 5 bottoms are sleeved on outside lower contact 10 tops, linked hole 12 is arranged in the lower contact 10, and sealing shroud 9 is sleeved on outside the lower contact 10, the linked hole 12 that sealing shroud 9 covers in the lower contact 10, sealing shroud 9 is fixed in the lower contact 10 by pin 8, valve seat 5 lower seat are on sealing shroud 9, and lock ring 7 is sleeved in the lower contact 10, and valve seat 5 lower inner wall have lock ring groove 11.Valve seat 5 upper inside wall diameters are greater than lower diameter, and making between valve seat 5 and the lower contact 10 has cavity 13.Water nozzle 14 is arranged on the fuse 6.
During to the water injection string pressure testing, slide-valve 4, valve seat 5 is motionless, water injection hole in sealing on the pipe 3, make water injection string be in air-tight state, can realize pressure testing to water injection string, not needing to drag for throwing fuse 6 just can be to water injection string pressure testing and water filling, and meanwhile, pressure imports into through linked hole 12, promote the sealing shroud 9 descending pins 8 of cutting off, discharge lock ring 7, after pressure testing finishes, pressure balance, slide-valve 4, valve seat 5 is descending under the effect of spring 2, the lock ring groove 11 of valve seat 5 lower inner wall hangs on the lock ring 7, makes the valve seat 5 can not be up, and the sealed cover in valve seat 5 bottoms 9 is spacing, therefore, valve seat 5 is in stationary state, and pressure reduction makes slide-valve 4 open water filling during formal water filling, and sealing shroud 9 continues to seal the linked hole 12 in the lower contact 10.
