Title:
DOWNHOLE ELECTRONIC TRIGGERING AND ACTUATION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/241806
Kind Code:
A3
Abstract:
A triggering mechanism for downhole equipment includes a housing for inserting downhole in an oilfield wellbore and associating downhole with a computer processor, a clock, at least one sensor circuit, and an electrical power source. The computer processor includes computer processing circuitry and a computer readable memory circuit. The sensor circuit senses at least a pressure parameter associated with the pressure within the oilfield wellbore downhole environment. A valve control circuit controls a valve and controls flow of control fluid to a hydromechanical device operating in association with the downhole tool within the oilfield wellbore. The valve control commands derive from real-time sampling of the downhole physical parameters to form ratio-based derivative values relating to physical parameter differences over a predetermined time span. In response to the ratio-based derivative values, the triggering mechanism generates triggering commands for flowing the control fluid to the associated hydromechanical device.
