摘要:
Systems and methods for guiding a seal assembly associated with a string of production tubing, or a tubular member generally, into a receptacle within a wellbore. The muleshoe of a seal assembly is provided with an auto entry guide device in the form of a guide member or kickover lug that is radially moveable with respect to the muleshoe. The kickover lug is collapsible radially inwardly and biased radially outwardly. The auto entry guide device may also include a centralizer bowspring that is mounted upon the muleshoe. Additionally, the muleshoe is mounted for rotational movement with respect to the seal assembly.
