A method of and device for flow testing multiple zones in a wellbore

摘要

The tool string 1500c straddles and tests multiple zones individually. The packers 1505a, b may be inflated adjacent one of the zones to straddle the zone. The electronic shut-in tool ESIT 1505a port opens to allow production fluid into a bypass path in fluid communication with the production logging tester PLT. The production fluid travels along the bypass path to the PLT 1510a, b which measures the flow rate of the fluid. The data may be stored in an internal memory unit or transmitted. The packers may then be deflated. The tool string 1500c may then be moved to the next zone of interest and the sequence repeated. The tool string 1500c provides for collection of the flow test data in the wellbore 15 instead of at the surface. The perforation gun may be included to further perforate zones or create a new zone in the same trip.
