Abstract: A downhole hydraulic tool employing multiple nozzles in a selectable fashion from an oilfield surface. At least one of the nozzles of the tool is equipped with a burst disk such that fluid pressure directed from the surface may be utilized in activating the nozzle. The pressure may be driven to exceed a predetermined level for sake of the activating by way of sealing off access to other nozzle(s) therebelow, for example, by way of standard ball drop techniques. Thus, nozzle selectivity may be taken advantage of when a first nozzle wears out without requiring time consuming removal of the tool from the well for sake of remedial repairs or replacement.

Abstract translation: 井下液压工具，从油田表面以可选择的方式采用多个喷嘴。 工具的至少一个喷嘴配备有爆破盘，使得从表面引导的流体压力可用于启动喷嘴。 例如通过标准的球滴技术，压力可以被驱动超过预定水平，以通过密封对其下方的其它喷嘴的接近进行激活。 因此，为了补救维修或更换，喷嘴选择性可以利用当第一喷嘴磨损而不需要耗时地从井中移除工具时。
