摘　　要：针对裂缝性油藏开发过程中出现的注采井间的窜流问题,应用模糊综合评判法,根据油田开发实践,选出油田地质静态特征指标和反映油田发生水窜的动态特征指标,用数学方法进行无量纲化处理,得到针对油水井的评价指标集,确定各评价指标的权重,利用权重系数法计算出评价对象的综合评价指数,提出注采窜流井区评价标准,最后根据目标油水井的综合指数来判别其窜流程度。通过在BD油田的实际应用,证明该方法的可行性,具有一定的应用前景。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.
