Abstract:

Whether high rate non-Darcy flowcan take place in lowpermeability reservoirs, the answer isyes if the Reynolds number is high enough. Whether high rate non-Darcy flowis easier to take place in lowpermeability reservoirs or in high permeability reservoirs, the answer is that it is easier to take place in high permeability reservoirs
because the smaller pores in lowpermeability reservoirs tend to confine fluids flow. However measurements in lab show the non-Darcy coefficients of lowpermeability cores are higher than those of high permeability cores, which implies that high rate non-Darcy flowis easier to take place in lowpermeability reservoirs than in high permeability reservoirs. This is a false appearance in experiment. The measurements in lab are seldom applied to field analysis, while well test data are the best choice for engineers to research the gas flow in reservoirs. All the deliverability equations of gas wells contain a term of high rate non-Darcy flowregardless of high permeability reservoirs or lowpermeability reservoirs. All the equations have the same form, but the equations coefficients take different values.
