Embodiment 2
[0155] Example 2 With the help of reservoir numerical simulation technology, a positive-rhythm oil reservoir with high permeability zones with grid division of 21×21×2 was constructed. The grid size is DX=DY=20m, DZ=10m, and there are 9 wells in the reservoir 5 injection and 4 production, separate injection and combined production, the permeability field distribution is as follows Figure 5a , Figure 5b As shown, the initial reservoir saturation is 0.2, and the oil-water viscosities are 1.0 and 20.0 mPa·s, respectively. The production dynamic simulation calculation of the reservoir was carried out by using mature digital simulation software. The simulated production time was 900 days, the overall injection-production balance of the reservoir was achieved, and the water cut of the final block reached 82.0%.
[0156] Using inter-well connectivity of multi-layer reservoirs to simulate the production performance in the first 900 days, it takes 0.22 seconds for one calculation, w...
Embodiment 3
[0160] Example 3 involves an overseas multi-layer water flooding oil field. 12 wells in an experimental area have 6 injections and 6 productions. Simulation calculations are carried out. The reservoir is divided into three layers in total, with separate injection and production. Through automatic history matching, the previous 2011 days, Invert model parameters, output information such as water injection splitting and oil displacement efficiency at the last moment, and then adjust the reservoir development plan.
[0161] The historical fitting of cumulative oil production and water cut production dynamics in the block is as follows: Figure 13a , Figure 13b As shown, the figure shows that the oil-water dynamics of the reservoir have been well fitted, and the fitting correlation coefficient has reached more than 95%. At the same time, according to the parameter field results after inversion, the simulation outputs the water injection splitting information of each layer at the...
