METHOD AND AN ARRANGEMENT FOR CONTROLLING FLUID FLOW INTO A PRODUCTION PIPE

摘要

A method of controlling fluid flow into a heavy oil production pipe includes reducing inflow into the production pipe locally from hot spots using inflow control devices including a movable body provided within a housing, the movable body being arranged to adjust the flow of fluid through the inflow control devices autonomously by exploiting the Bernoulli principle; increasing inflow into the production pipe remote from the hot spots using the inflow control devices to increase inflow locally; and increasing draw down in the production pipe by using an injector to inject a gaseous medium at or downstream of the inflow control devices.
