| description | The invention provides a method for determining oil-water spatial distribution of a heavy oil reservoir by using a heavy oil fluid potential. The method comprises the following steps: step 1, calculating a starting pressure gradient of the heavy oil reservoir; step 2, calculating the thick oil fluid potential considering the starting pressure gradient; 3, establishing a thickened oil fluid potential three-dimensional model; 4, determining a thick oil fluid potential value of the oil-water interface; and 5, determining the oil-water spatial distribution of the heavy oil reservoir. According to the method for determining the oil-water spatial distribution of the heavy oil reservoir by using the fluid potential of the heavy oil reservoir, the influence of the starting pressure gradient in non-Darcy seepage oil reservoirs such as the heavy oil reservoir on the fluid potential is considered, a fluid potential calculation method for the non-Darcy seepage oil reservoirs such as the heavy oil reservoir is established |
