摘要： In one aspect, a method of estimating fluid flow contribution from each producing zone of multi-zone production well is provided, which method may include: defining a wellhead pressure; determining a first inflow performance relation (IPR1) between pressure and fluid inflow rate at a first producing zone and a second inflow performance relation (IPR2) between pressure and fluid inflow rate at a second producing zone; determining a combined performance relation (IPRc) between pressure and fluid inflow rate at a commingle point; defining an initial fluid flow rate into the well from the first zone and an initial fluid flow rate from the second zone; generating a first fluid lift performance relation (TPR1) between pressure and total fluid flow corresponding to the commingle point using the initial fluid flow rates from the first and second production zones and at least one fluid property; and determining contribution of the fluid from the first zone and the second zone at the commingle point using IPRc and TPR1.

摘要： A system and method for controlling inflow of fluid into a production string. In aspects, the invention provides a downhole sand screen and inflow control device with a gas or water shut-off feature that can be operated mechanically or hydraulically from the surface of the well. The device also preferably includes a bypass feature that allows the inflow control device to be closed or bypassed via shifting of a sleeve. In embodiments, the flow control device can be adaptive to changes in wellbore conditions such as chemical make-up, fluid density and temperature. Exemplary adaptive inflow control devices include devices configured to control flow in response to changes in gas/oil ratio, water/oil ratio, fluid density and/or the operating temperature of the inflow control device. In other aspects of the present invention, inflow control devices are utilized to control the flow of commingled fluids drained via two or more wellbores.
