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 reservoiror 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 differentialpressure for autonomously adjusting the flow of thefluid in order to ensure a substantially constant volume rate from theinjector (24) to the reservoir or formation along an injectorlength.
