Recognize the Low-efficiency Water Passage in Multilayer Non-uniform Reservoir with Fuzzy Evaluation

摘要：

For multilayer sandstone reservoir 1, high permeability water passage would be formed between oil well and water well at the later stage of water drive. This caused the injected water circulation with no or low efficiency and thus decreased the production of oil wells. In order to improve the effect of water drive, measures of profile control and/or water shutoff must be taken. The key problem is to recognize the wells and layers having ineffective or low-efficiency water passage. In this paper, the identifying indexes have been determined and corresponding mathematical model has been constructed with fuzzy theory.
