AUTONOMOUS BLOWOUT PREVENTER

摘要

An autonomous BOP system is provided for stopping an uncontrolled flow of formation hydrocarbons comprising two or more sensors distributed along a length of a subsea blowout preventer to monitor a drill pipe inside a blowout preventer and measure critical parameters. A subsea computer using predictive-software monitors a blowout preventer along with material critical parameters and calculates a blowout preventer configuration and sequence to arrest a well blowout. Blowout preventer components are fine-tuned and operational modes are added to aid an arrest of a well blowout under realistic conditions.

1. A well monitoring system for a subsea BOP, said subsea BOP defining a wellbore through said wellbore, said subsea BOP comprising at least two BOP rams, said at least two BOP rams comprising a shear ram, said at least two BOP rams further comprises at least two pistons which further comprise a shear ram piston, at least one accumulator to stroke said shear ram piston associated with said shear ram, a string of pipe moveable within said wellbore, said string of pipe comprising a plurality of pipe connectors and a plurality of pipe bodies between said pipe connectors, said well monitoring system comprising:
at least one subsea computer, said at least one subsea computer being operatively connected to said at least two BOP rams and said at least one accumulator and said at least one subsea computer; and software operable on said at least one subsea computer to control an activation timing of said at least two BOP rams to control said subsea BOP.
