摘要: A sealing element (22) that swells on exposure to well fluids present or added the wellbore is assembled mandrel (24) in a manner induce circumferential stresses proximately inside diameter of so as resist tendency grow during swelling process. vacuum and pressure method are described. Leak paths between minimized eliminated result.
