发明名称 ISOLATING MULE SHOE
摘要 Systems and methods are disclosed that include providing an isolating mule shoe having an integrated axial isolator coupled to a landing sleeve of a drill string at an upper end of the axial isolator. The axial isolator includes an elastomeric component that is coupled between a first component and a second component. The first component and the second component are configured to displace axially with respect to one another as a result of a force imparted upon the landing sleeve to provide vibration control.
