摘要： A wellbore servicing system comprising a work string and a valve tool defining an flowbore, wherein the valve tool is transitionable from a first mode to a second mode, from the second mode to a third mode, and from the third mode to a fourth mode, wherein the valve tool transitions from the first mode to the second mode upon an application of pressure to the flowbore of at least a threshold pressure, wherein the valve tool transitions from the second mode to the third mode upon a dissipation of pressure from the flowbore to not more than the threshold pressure, wherein, in the first mode, the valve tool allows fluid communication via the flowbore in a first direction and disallows fluid communication in a second direction, and wherein, in the second, and third modes, the valve tool allows fluid communication in both the first and second directions.

摘要： Provided is a method for connecting coiled tubing strings, as well as a flexible stabbing snake. In one aspect, the method for connecting coiled tubing strings includes lowering a downhole end of a first coiled tubing string within a wellbore, and coupling an uphole end of the first coiled tubing string to a downhole end of a second coiled tubing string at a location between a coiled tubing injector and the wellbore to form a combined coiled tubing string. In at least one aspect, the method further includes lowering the combined coiled tubing string within the wellbore.

摘要： Actuatable valve tool including a tubular housing forming an axial flowbore. A slidable flow tube disposed within the housing and a shear sleeve disposed around at least a portion of the slidable flow tube. One or more valves disposed within the housing, each having an open position and a closed position. In the open position the one or more valves permit fluid flow within the axial flowbore, and in the closed position the one or more valves block fluid flow therethrough. The slidable flow tube moveable within the housing to transition the one or more valves between the closed position and the open position.
摘要翻译：可操作的阀工具包括形成轴向流动孔的管状壳体。设置在壳体内的可滑动流管和围绕可滑动流管的至少一部分设置的剪切套筒。设置在壳体内的一个或多个阀门，每个阀门具有打开位置和关闭位置。在打开位置，一个或多个阀允许流体在轴向流动孔内流动，并且在关闭位置，一个或多个阀阻止流体流过。可滑动的流量管在壳体内可移动，以在关闭位置和打开位置之间转换一个或多个阀。
