Investigation of effective drive theory on Non-Darcy with low permeability in Fuyu oil reservoirs

According to the experiment and non-linear pore flow theory with extra-low permeability,the mathematics models with kickoff pressure gradient for all process are found.The new forecast method of effective drive pressure considering well pattern construction is set up.The effective drive theory on Non-Darcy with low permeability is given out.The effective drive radius and optimization distance of water well with oil well for some pattern construction are simulated.The test is very well in Block 33 of Fuyu oil field.The optimization injection and production pressure are given out.The simulation results and practice data is identical.The numerical simulation results show that the models and o method are good and an application of theory models has substantiated.
