摘要： A fluid cutting tool and method for perforating or severing tubular members from inside. The tool is especially suited for use with a rotational drive system, such as a downhole motor, to separate downhole structures, such as stuck production tubing. The cutting tool preferably takes the form of an elongate metal body with an open first end connectable to the end of a downhole motor. The downhole end of the tool may be conical. A fluid conduit within the body of the tool communicates with the fluid channel in the downhole motor. Ports in the sides of the tool body direct jets of cutting fluid out the side of the tool. The tool attached to the motor is fed downhole until the tool is at the desired location in the well. Then the motor is operated to rotate the tool while cutting fluid is pumped through it. This causes the jets of fluid to be directed at the inner surface of the production tubing (or other tubular structure). This process is continued until the tubing is perforated or severed, as needed.
摘要翻译：一种用于从内部穿孔或切断管状构件的流体切割工具和方法。该工具特别适用于诸如井下电动机的旋转驱动系统以分离井下结构，例如卡住的生产管道。切割工具优选采用细长金属体的形式，其具有可连接到井下电动机的端部的敞开的第一端。工具的井下端可以是圆锥形的。工具主体内的流体导管与井下电机中的流体通道连通。工具主体侧面的端口将切削液直接喷出工具的侧面。连接到电机的工具进入井下，直到工具位于井中所需的位置。然后在切割流体被泵送过程中，马达被操作以旋转工具。这导致流体射流被引导到生产管道（或其他管状结构）的内表面。根据需要，连续进行管道穿孔或切断。

摘要： A rotary device, such as a downhole motor, with a rotary wave seal assembly. The seal assembly is formed by a sinuous or non-linear circumferential gland or groove and an annular seal member, such as an O-ring, supported in the groove. The device further includes at least one thrust bearing assembly for transmitting axial pressure from the bearing housing to the drive shaft. Each thrust bearing comprises a self-lubricating thrust washer as the bearing element. Still further, where the rotary device comprises two coaxial tubular structures that are not to rotate relative to each other, an anti-rotation means is provided. The anti-rotation means includes a cylindrical pin received in mating longitudinal, radiused grooves in the outer wall of the innermost elongate member and the inner wall of the outermost tubular member. The anti-rotation means includes a cylindrical pin received in the mating longitudinal grooves. This configuration allows axial, sliding movement of one tubular member relative to the other, but prevents rotational movement therebetween. Where the rotary device is a downhole motor, it further comprises a radial bearing sleeve positioned between the coaxial downhole ends of the universal housing and the connecting rod, above the bearing section of the motor. This sleeve acts as a barrier to prevent debris in the drilling fluid from moving into the bearing assemblies.

摘要： A tubing conveyed tool for use in perforating a well bore utilizing abrasive perforating techniques. The perforating tool is particularly useful in non-vertical wells. The perforating tool is designed to permit running and setting a bridge plug, and then perforating the well bore without requiring the removal of the tool string. An eccentric weight bar can also be used to allow for directional perforating in non-vertical wells. The eccentric weight bar uses gravity to cause the bar to rotate to a predetermined position.

摘要： A bottom hole assembly comprising a hydraulic setting tool, a frac plug, and usually also an adapter for connecting the frac plug to the setting tool. The setting tool, adapter, and frac plug, all include continuous flow passages that allow fluid to be circulated in the well ahead of the plug as the bottom hole assembly is advanced. This removes debris present in the well and prevents the frac plug from becoming lodged in the well in other than the desired location. The setting tool includes a bypass feature that signals reliably when the plug has been successfully deployed. The bypass assembly comprises sliding members with bypass ports that can become aligned only when the collar on the frac plug has advanced far enough to ensure complete deployment of the frac plug.
摘要翻译：底孔组件，其包括液压设置工具，压裂塞，并且通常还具有用于将压裂塞连接到固定工具的适配器。设置工具，适配器和压裂塞都包括连续流动通道，当底部孔组件前进时，允许流体在塞子前部的孔中循环。这消除了存在于井中的碎屑，并且防止压裂塞从储存在井中而不是期望的位置。设置工具包括一个旁路功能，当插头已经成功部署时可以可靠地发出信号。旁路组件包括具有旁路端口的滑动构件，只有当压裂塞上的套环已经前进得足够远以确保压裂塞的完全展开时才能对准。
