The Methods of Development Index Prediction Applicable to Low Permeability Reservoir

Combining the features of low permeability reservoir water flood development and supposing that the formation was homogeneous and is opachous while the fluid was incompressible and gradually formed without considering the difference between densities of water and oil, this paper applies to Streamline Integration Method and Unit Analysis Principle on the basis of Low-Speed Non-Darcy Flow Formula obtained from in-house laboratory investigation, and finally derives the Index Prediction Mathematical Model considering the starting pressure gradient, which is reasonable and applicable to the development index prediction calculation of low permeability reservoir with the validation of oil field development actual data.
