摘要： A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with a removable insert which contains one or more magnets. The insert is formed such that both the north and south magnetic poles of the one or more magnets are able to attract metallic debris.

摘要： Downhole valves comprise a housing having a bore, a port, upper and lower recesses disposed in an inner wall surface of the bore, the upper recess disposed above the port and the lower recess disposed below the port, and upper and lower pistons disposed in the bore. The upper and lower pistons each comprise a bore with a port in communication with housing bore. During run-in, the housing port is blocked by the lower piston. Actuation of the lower piston unblocks the housing port and aligns the lower piston port with the lower recess. Actuation of the upper piston closes the housing port and aligns the upper piston port with the upper recess. Alignment of the ports of the pistons with their respective recesses permits fluid flow through the tool both when the valve is opened by the lower piston and closed by the upper piston.

摘要： A fluid bypass tool that can be incorporated into a fishing arrangement between a fluid-operated latching tool and a fluid-operated jarring tool. The latching tool is actuated with fluid from the surface to be latched to and unlatched from a stuck tool in the wellbore. The bypass tool permits fluid flow to the latching tool to be interrupted so that the jarring tool may be operated without risk of inadvertently causing the latching tool to unlatch from the stuck tool.
摘要翻译： 流体旁路工具，其可以结合到流体操作的闭锁工具和流体操作的冲击工具之间的钓鱼装置中。 锁定工具由来自表面的流体致动，以被锁定并从井眼中的卡住的工具解锁。 旁路工具允许流体流向闭锁工具以被中断，使得可以操作刺耳工具，而不会有意图无意地导致闩锁工具从卡住的工具松开。
