Abstract
For controlling a hydrocarbons production installation, comprising at least one hydrocarbons production string activated by a gas injection using a gas injection choke, and a production choke on the string, a method comprises a production phase during which the position of at least one of the chokes is adjusted by cascaded control loops. The loops are driven according to continuously or sequentially developing setpoint parameters. The installation can be controlled more accurately and quickly than in the prior art, as a cascade control loop architecture makes it possible to simplify each of the loops in order to increase the speed of implementation, while still taking account of a greater number of setpoint parameters.
