One Trip Interventionless Liner Hanger and Packer Setting Apparatus and Method

摘要

A liner hanger and packer are set at different times in a single trip without intervention. The running tool has a ball seat that accepts a ball for pressuring; up which results in movement of a mandrel with a magnet mounted to it past a valve triggered by the magnetic field. Potential energy is released to set the liner hanger. Further mandrel movement then releases the running tool once the liner is supported by the hanger. After a cement job that starts with confirmation of release of the running tool, the same magnet is moved past another valve adjacent the liner top packer. Another valve is triggered open to release potential energy and move parts that set the packer. The running tool is removed from the liner and brought to the surface.

主权项

1. A method of operating multiple tools with actuators therefor at a subterranean location, comprising:
running in, to a predetermined subterranean location, a tubular string on a running tool, said running tool connected adjacent a lower end of a running string; mounting the multiple tools and actuators therefor exterior to said tubular string for said running in; mounting a triggering device on said running tool for said running in; sequentially setting said multiple tools with said triggering device with movement of said running tool relative to the tubular string triggering at least one of said multiple tools to set; releasing from said tubular string and removing said running tool and running string from the subterranean location.
