Identifying Study on the Channeling Severity of Injection and Production in Fractur Fractured Reservoirs of BD Oilfield

In view of the channeling between injection and production wells in fracturing reservoirs during the oilfield development,the static geology characteristic indicators chosen and dynamic characteristic indicators chosen that can reflect water channeling are dimensionlessly processed by using mathematical methods,thus obtaining the evaluating indicator set for oil and water wells and the weighted indicators.The comprehensive evaluation indicators of the evaluated targets are calculated by using weighted coefficients,the evaluating criteria are raised for the channeling-well region of injection and production and the channeling severity is identified based on the comprehensive indicators of oil and water wells.The application in BD Oilfield proves that the method is feasible and prospective for its future application.
