SUBTERRANEAN WELL TOOL INCLUDING A LOCKING SEAL HEALING SYSTEM

摘要

An apparatus for maintaining a compression force on an elastomeric member of a downhole tool, comprising: a piston head and a translating driver defining a chamber wherein the chamber defines a region of relatively low pressure: wherein the piston head and the translating driver are moved apart upon setting the tool downhole: and wherein a well pressure acts on the translating driver to urge it towards the piston head, thereby maintaining a compression force on the elastomeric member. 2012960v2 |6 32F---- 4|o --- 4 420- 42b-- -- - 2 470- 44- ~ 45- 3 48--~ - 4g Fig. 1 A
