Numerical simulation in Tuoshi low permeability reservoir

A geologic model for the south fault block of Tuo 11 fault nose is established. On the basis stated, a simulation study is performed by using a numerical reservoir simulating software of non-Darcy percolation of a self-developed dynamic geologic model. The following conclusion is achieved: the geologic model for the south fault block of Tuo 11 fault nose is a dynamic one, percolation in Tuo 11 low permeability reservoir is a low permeable non-Darcy flow with low oil saturation centering at injector line and with high oil saturation at both sides, injected water advances along fractures, oil saturation is low around fractures, remaining oil saturation is distributed in continuous sheet approximately. A rational development-adjustment scheme is proposed.
