METHOD FOR SELF-ADJUSTING (AUTONOMOUSLY ADJUSTING) THE FLOW OF A FLUID THROUGH A VALVE OR FLOW CONTROL DEVICE IN INJECTORS IN OIL PRODUCTION

摘要

A METHOD FOR INJECTING A FLUID INTO AN OIL AND OR GAS RESERVOIR OR FORMATION, IN WHICH THE FLUID FLOWS INTO THE RESERVOIR OR FORMATION THROUGH A PLURALITY OF AUTONOMOUS VALVES OR FLOW CONTROL DEVICES (2) PROVIDED ALONG AN INJECTOR (24), THE VALVES (2) HAVING A SUBSTANTIALLY CONSTANT FLOW-THROUGH VOLUME ABOVE A GIVEN DIFFERENTIAL PRESSURE FOR AUTONOMOUSLY ADJUSTING THE FLOW OF THE FLUID IN ORDER TO ENSURE A SUBSTANTIALLY CONSTANT VOLUME RATE FROM THE INJECTOR (24) TO THE RESERVOIR OR FORMATION ALONG AN INJECTOR LENGTH.
