In this paper, the influence factors of forming high capacity channel and its development characters have been analyzed, and the judging indices of low efficiency circulation well have been determined. Low efficiency wells have been elementary selected by using the method of fuzzy judgment. By the contrast of static data of each layer and sedimentary facies, and the contrast of correlativity between oil wells and water wells, layers with low efficiency circle have been made out ultimately. Using the compiled software based on this method, data of North-Sandong dong block in Daqing Oilfield have been studied. The coincidence rate of results between the software and artificial choice was 81.7%. This method is feasible, and it can improve the work efficiency and veracity.
