Abstract
This paper mainly studied the influence of starting pressure gradient in CO2flooding. The capillary pressure of low permeability reservoir is much larger than the ordinary reservoir, so that the influence of starting pressure gradient can not be ignored. Since CO2flooding will be widely used in the development of low permeability reservoirs, it is necessary to study the influence of starting pressure gradient. This paper mainly used Runge Kutta Fehlberg Method and Adams Fourth-order Predictor-Corrector to solve the black oil model, which was founded to study the process of CO2flooding. These two methods considered the starting pressure gradient during the CO2flooding, and the influence of reservoir permeability and crude oil density were studied by founding black oil model and use these two methods to solve the model. We have compared the production rate with staring pressure gradient and without starting pressure gradient.
