摘要
Integrated horizontal selective testing of production flow from individual perforations or individual lateral branches of a highly deviated or horizontal multilateral branch well is accomplished by a downhole flow rate testing tool which is selectively positioned within the wellbore by a coiled tubing deployment system for multiple downhole production flow rate tests to indicate the production flow rates of individual lateral branches or perforated zones. Logging tools are on-board the downhole flow rate testing tool for accuracy of tool location and for conducting downhole production flow rate tests. A multi-phase flowmeter at the surface measures the total production flow rate of fluid flowing in the flowline of the well. Real-time downhole flow measurements are correlated to provide a production flow rate profile. The well operator may take remedial action using on-site equipment if the tests show excessive water or gas from any lateral branch.
