摘　　要：对于长期注水开发过程中形成的优势渗流通道,主要采用可动凝胶调驱来进行治理,而调驱剂用量设计是治理效果好坏的主控因素。锦16块二元驱试验区进行整体调驱时,应用示踪剂资料对常用调剖剂用量设计公式中的调驱半径和方向系数进行了必要的修正,考虑了注水推进速度在各井组间的差异和各向异性。实例证明,该方法适合明显存在优势渗流通道情况下注聚合物前的整体调剖设计。The predominant flow path formed during long-term water flooding process has been mainly treated with movable gel to conduct profile control,and the dosage of the profile control agent is decisive to treatment result.In Jin 16 block,tracer data has been used to correct the radius and direction coefficient in the traditional dosage equation of profile control agent.The differences of water advance speed between well groups and anisotropy are taken into account.It has been proved by practice that this method is suitable for integral profile control design before polymer injection under the condition that there exists obvious predominant flow path.
