Non-linear Flow in Low Permeability Deformation Reservoir
The practical oil field development and experiment study shown that the mechaniCS of fluidsflow is not consisting with Darcy formula in low permeability reservoirs．According to the experimentand pervious studies,the non linear flow model with two parameters was presented in this paper. On thebasis of the model,the non linear flow model with deformation characteristics of the low permeabilitywas established. The difierence among Darcy model．Darcy model with deformation and non linearmodel with deformation were discussed by analysis and calculation of Daqing oil field examples. Theresults showed that draw down of non linear model with deformation were bigger than others．Wellproductivity decreased with increasing of the non-linear degree and deformation coefticient. The growthof PI slowed down with the increasing of drawdown．So．smaller well distance and higherinjection／production pressure difierence were needed for effectively developing low permeabilitydeformation reservoirs.
