Artificial barrier morphology distribution mechanism and the EOR factors of he heavy oil reservoir with bottom water is be researched, Through numerical calculation and numerical simulation method. The model for calculating the height of the artificial-interlayer with curvilinear side surface is established. This model quantitatively describes the relationship between the artificial-interlayer height and oil yield, reservoir thickness, radial distance from well axis, reservoir permeability and crude oil viscosity. Maximum artificial-interlayer height and radius, the artificial-interlayer heights at different radial distances can be obtained according to this model. Through the case, the characteristics of artificial-interlayer form are analyzed, and rules of artificial-interlayer conformation are obtained when artificial-interlayer liquid with different volume, viscosity and race are injected. The further research are carried out through numerical simulation method, and the theoretical results are be Compared and verified which deepen the study of artificial-interlayer shape influence factor. Results show that: the volume and position of injected gel have more influence on development effect is obviously, the interlayer is designed 3M over the oil-water interface and thickness perforated is 6m is better, which provides a reference for the development of bottom-water reservoir.
