Embodiment Construction
[0030] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.
[0031] Such as figure 1 as shown, figure 1 It is a flow chart of the numerical simulation method considering nitrogen injection in the present invention.
[0032] Step 1: Define a two-phase three-component model in the model. The three phases and three components are three components of oil, water and nitrogen and three phases of oil, water and gas.
[0033] Step 2: collect the experimental data of the viscosity of the three components changing with temperature. The crude oil viscosity data in this data is the surface degassed crude oil viscosity. Collect the dissolved oil-gas ratio of the target block. The formula is used to correct the viscosity data of crude oil and convert it into the change data of underground crude oil viscosity with t...
