发明名称 RESISTOR ACTUATOR RELEASE SYSTEM AND METHODOLOGY
摘要 A technique facilitates actuation of a tool via shifting of a first portion with respect to a second portion. A release mechanism initially is engaged between the first portion and the second portion to hold the second portion relative to the first portion in a first operational position. The release mechanism is secured in this initial position by an electrical resistor. By selectively applying sufficient electrical power to the electrical resistor, the electrical resistor disintegrates and allows release of the release mechanism. As a result, the first portion and the second portion may be shifted to a second operational position.

主权项 1. A system for use in a well, comprising: a well string having a well tool actuatable between a first position and a second position, the well tool being initially held in the first position by a release mechanism, the release mechanism comprising: a mechanical release mounted to a first portion and having a catch member releasably engaged with a second portion; a carbon composition resistor positioned to physically hold the catch member in engagement with the second portion until sufficient electrical power is applied to the carbon composition resistor to disintegrate the carbon composition resistor, thus releasing the catch member from the second portion to enable relative movement between the first portion and the second portion which, in turn, shifts the well tool between the first position and the second position.
