With developing rapidly for China's economy, the demand of petroleum resources is growing, and the difficulty of petroleum exploration and development
It is increasing；The main force oil field of China, such as grand celebration, Shengli Oil Field comes into height/super-high water-cut stage, but still
There is substantial amounts of crude oil to reside in stratum, recovery ratio is relatively low；Therefore, the oil recovery factor of developed field how is further improved
It is increasingly important.
During water flooding, due to oil reservoir plane and longitudinal direction anisotropism, the difference of profit viscosity and
The injection-production relation of flooding pattern is uneven, produce water injection well to producing well tonguing and along high permeability formation advance by leaps and bounds the problem of, cause injection
The low effective circulation of water, and hyposmosis band in oil reservoir, the hyposmosis area with floor are not involved, still suffer from substantial amounts of remaining oil.
Therefore, it is the important method for improving oil recovery factor to improve injection water swept volume；Wherein, water injection well transfer drive technology
As a kind of effect is good, low cost technology is widely applied, preferable decreasing water cut and increasing oil effect is achieved, it has also become improve
Water flooding effect, the cost-effective means for realizing old filed stable yields.
In order to evaluate the transfer drive performance of various water injection well profile control agents, it usually needs according to the heterogeneous conditions of oil reservoir, build
Nonhomogeneous soil layers；Traditional heterogeneous artificial cores model is compressed together by the rock core of different permeabilities, manufacture craft
Extremely complex, common lab condition can not make, and cost is higher.
At present, conventional nonhomogeneous soil layers are heterogeneous parallel double tube models；Because the modelling is simple, metering
It is convenient, play very important effect in terms of the plugging characteristics and bifurcated characteristic of evaluating the profile control agents such as gel, foam；But
