摘　　要：以大庆油田萨北开发区北2-20-P60井组为实例,解剖分析了该井组4口井水力探测曲线的形态、大孔道识别结果和剩余油分布状况。通过对该井组精细地质研究及井组注水开采动态变化的对比分析,认为该方法对于加深层状砂岩油田地质认识、研究储层大孔道和剩余油分布状况以及探索治理挖潜的有效途径具有实用价值。预计扩大应用范围后,将对高含水后期控制注入水的低效和无效循环,降低开采成本,改善开发效果产生积极影响。This paper introduces the method to study high permeability channel and remaining oil distribution by using hydraulic detection. Regarding B2-20-P60 pattern as the instance in Sabei developing zone of Daqing oilfield, it analyses the form of the curve in hydraulic detection. The result discerns the high permeability channel and remaining oil distribution of four wells in this pattern. Basing on fine geologic study, pattern performance and change a-nalysis, it shows that this method has practical value to intensify the geologic recognition of multi-sandstone reservoir, study high permeability channel and the remaining oil distribution, and choose an effective way to manage and tap the latent potential. It is necessary to continue carrying on field test study as a new method. After expanding and popularize the range of application, it is significant to control poor efficiency and invalid circulation of waterflooding during the latter period of high water cut, reduce the cost of production and improve the result of developing.
