Movable sealed type sliding sleeve opening tool

The invention provides a movable sealed type sliding sleeve opening tool. The tool comprises a body and an extrusion part, wherein the body is connected with an underground sliding sleeve and provided with a rubber barrel capable of being attached to the underground sliding sleeve after being extruded to expand; the extrusion part is movably arranged on the body and used for extruding the rubber barrel. After being extruded, the rubber barrel can be attached to the underground sliding sleeve, and therefore sealing between the sliding sleeve opening tool and the underground sliding sleeve is achieved, and the possibility that perforation liquid leaks to well sections under the sliding sleeve opening tool is reduced. Besides, the movable sealed type sliding sleeve opening tool is simple in structure, convenient to process and mount and low in cost. 本发明的活动密封式开滑套工具，包括：本体，与井下滑套连接，并设有能在挤压膨胀后与井下滑套贴合的胶筒；以及挤压件，可移动地设置在本体上，用于挤压胶筒。在胶筒被挤压后能够与井下滑套贴合，从而实现开滑套工具和井下滑套之间的密封，进而减少射孔液渗漏到开滑套工具以下的井段的可能性。而且该开滑套工具的结构简单，加工和安装方便，成本低。
