| 摘要 |
In the invention a thermal hydrocarbon recovery apparatus comprises a plurality of steam injector tubes each provided with a plurality of injector autonomous inflow control devices, AICDs, spaced apart from each other along the length of each steam injector tube; a plurality of production tubes each provided with a plurality of production autonomous inflow control devices, AICDs, spaced apart from each other along the length of each production tube; wherein said injector AICDs are arranged to inject steam into a geological formation so as to reduce the viscosity of hydrocarbons in the formation; and wherein said production AICDs are arranged to permit the flow of heated hydrocarbons into said production tubes for movement to the surface. |
