摘要： A carrier assembly having at least one sealing cup, a fluid bypass and adjustable wash nozzles, as well as a spear assembly having a central through bore, are attached to the distal end of a length of continuous tubing and inserted in to the flow bore of a pipeline. Fluid is pumped through the annular space between the carrier assembly and the pipeline, providing motive force for advancing the carrier assembly within the pipeline. Fluid can bypass the carrier assembly, enter the central bore of the spear assembly, and return to the surface through the central bore of the continuous tubing. A stuck pig or other obstruction is speared, and thereafter retrieved from the pipeline on the continuous tubing.

摘要： A wireline deployed fluid blasting tool for removing obstructions from oil and gas wellbore tubing is disclosed. The tool has an inner tubular mandrel retaining a releasable outer sleeve creating an annular fluid passage in communication with fluid ejection ports. Resilient seals seal the annulus between the tool and the wellbore tubing allowing fluid pressure above the tool to advance the tool through the tubing. Fluid enters the annular fluid passage through fluid perforations in the outer sleeve to exit the fluid ejection ports to create a fluid blast to remove obstructions. The outer sleeve shifts along the inner mandrel by fluid pressure to open fluid inlet passages into the inner mandrel allowing fluid to enter and exit through the mandrel while bypassing the annular fluid passage and fluid ejection ports to facilitate pulling the tool from the tubing.
摘要翻译：公开了一种用于从油气井管中除去障碍物的有线部署的流体喷射工具。该工具具有保持可释放的外部套筒的内部管状心轴，其产生与流体喷射口连通的环形流体通道。弹性密封件密封工具和井筒管之间的环形空间，允许工具上方的流体压力将工具推进通过管道。流体通过外套管中的流体穿孔进入环形流体通道以离开流体喷射口以产生流体鼓风以去除障碍物。外套筒通过流体压力沿着内心轴移动，以将流体入口通道打开到内心轴中，允许流体通过心轴进入和离开，同时绕过环形流体通道和流体喷射口以便于从管道拉动工具。

摘要： A method of cleaning a tubular with a cleaning tool that includes the steps of disposing the cleaning tool in the tubular, the cleaning tool having a main body with a first end, a second end, an inlet, an outlet, and a propulsion relief assembly disposed proximate to the second end. The method further includes the steps of sufficiently pressurizing fluid behind the tubular to propel the cleaning tool along the tubular, and increasing the pressure of the fluid to actuate the propulsion relief assembly, whereby fluid is jetted out the outlet and out of the propulsion relief assembly.
摘要翻译：一种用清洁工具清洗管状物的方法，包括将清洁工具设置在管状物中的步骤，清洁工具具有主体，其具有第一端，第二端，入口，出口和推进卸载组件靠近第二端设置。该方法还包括以下步骤：对管道后面的流体进行充分加压，以沿着管状物推进清洁工具，并且增加流体的压力以致启动推进释放组件，由此将流体从出口喷射出推进释放组件。
