摘要： Laterally directed deformation force is applied to structure at a selected location in a longitudinal bore hole, through use of a tool that comprises a pressure responsive actuator having a laterally displaceable plunger, and means to control fluid pressure application to the actuator. The tool is displaced lengthwise of the bore hole to selected location by running of a pipe string carrying the tool, and fluid pressure is transmitted within the string and its application to the actuator is controlled to effect lateral displacement of the plunger toward the structure outwardly of the tool, with resultant deformation of the structure. Flow beans may be selectively placed in the structure, as for example punched through well casing, by operation of the tool; and other deformation operations may be performed at selected locations in a well.
