Use of autonomous (self-adjusting) valves 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.
