Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of water blanket power ejector, comprise hollow ejector body 1, oil pipe connect buckle 2, sliding sleeve fuse 3, multiple nozzle assembly 4 and multiple shear pin 5 and sealing ring 6.Wherein, oil pipe connects and buckles the two ends that 2 are arranged on hollow ejector body 1; Multiple nozzle assembly 4 is arranged in the sidewall of hollow ejector body 1; Sliding sleeve fuse 3 is arranged on the inwall of hollow ejector body 1 by shear pin 5 and sealing ring 6 sealing, and slidably coordinates with hollow ejector body 1, for shutoff or de-plugging nozzle assembly 4.As shown in Figure 2, nozzle assembly 4 comprises nozzle 41 and nozzle gland 42, and nozzle gland 42 mounts cover on the outer face of nozzle 41 by buckle connected mode.
The water blanket power ejector that the utility model embodiment provides; by the mode connected with buckle on the outer face of nozzle 41, nozzle gland 42 is set; to protect nozzle 41; can prevent fluid impact from damaging nozzle 41 in pressing crack construction process; and ensure that nozzle 41 can not come off; make the jet effect of this water blanket power ejector more stable, be convenient to large-scale promotion application.
Be understandable that, in the water blanket power ejector that the utility model embodiment provides, the oil pipe being arranged on hollow ejector body 1 two ends connects to be buckled 2 and is used for this hydraulic ejector is connected with oil pipe.In addition, entering well, anti-flushing well to prevent the utility model ejector and adding in sand process at oil jacket, sand in well enters in the gap between sliding sleeve fuse 3 and hollow ejector body 1 by nozzle assembly 4, thus affecting the sealing performance of sliding sleeve fuse 3, sliding sleeve fuse 3 can be arranged on the inwall of hollow ejector body 1 by sealing ring 6 sealing by the utility model embodiment.And this sliding sleeve fuse 3 is fixed by shear pin 5 and hollow ejector body 1, thus realize and being slidably matched of hollow ejector body 1, so that under specific circumstances, shutoff or de-plugging are carried out to nozzle 41.Wherein, the sealing ring 6 used can be elastomeric rubber seal.
Further as shown in Figure 2, nozzle 41 with nozzle gland 42 is provided with the flowing hole 43 be connected, as preferably, nozzle 41 and nozzle gland 42 are provided with one heart with the flowing hole 43 in footpath, so that fluid controls and the test of fluid flow parameters.
