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, inwhich the fluid flows into the reservoir or formation through a plurality of autonomousvalves 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 the fluid in order to ensure asubstantially constant volume rate from the injector (24) to the reservoir orformation along an injector length.
