摘 要：

A method of controlling fluid flow into a heavy oil production pipe is disclosed. The method involves reducing inflow into a production pipe locally from hot spots using inflow control devices comprising a movable body provided within a housing. The movable body is arranged to adjust the flow of fluid through the inflow control devices autonomously by exploiting the Bernoulli principle. Inflow into the production pipe remote from said hot spots may be increased using the inflow control devices to increase inflow locally, and draw down in said production pipe may be increased by using an injector to inject a gaseous medium at or downstream of said inflow control devices. 主权项：
