| Abstract: | Production decline of water flooding in low permeability reservoir has been in use in the law of the high permeability reservoir analysis.This method is suitable for the low permeability reservoirs,which needs further verification.In view of this question,the paper conducts the deep research of the production decline in low permeability reservoir on the basis of the theory of low-speed non-Darcy flow,and then provides the relationship between production decline rate of oilfield and productive time and outpu... |
