| Abstract: | The axisymmertyical hyperbola function mathematical formulation of pressure fall-off curves is given by analysing the pattern of the generous pressure fall-off curves of the injection wells. The field tests prove that the fundamental and deduction formulation could select the type of the profile modificators, evaluate the effect of the profile modifiction/water blockage, guide the waterflood and oil production management. |
