High-precision three-dimensional modeling method and device for oil reservoir and storage medium

The invention discloses a high-precision three-dimensional modeling method and device for an oil reservoir and a storage medium. The method comprises the following steps: acquiring internal lateral lamination data of a meandering river; characterizing the lateral build-up layer; and according to the lateral build-up, establishing an internal lateral build-up model of the meandering river point dam. According to the oil reservoir high-precision three-dimensional modeling method and device and the storage medium, nine-level configuration distribution in a meandering river point dam is represented in a three-dimensional space by editing the fault plane, the modeling process is improved, a lateral build-up development mode is represented by using the fault plane style, and the modeling efficiency is improved. In the numerical simulation process, the shielding effect of the lateral lamination on the fluid is simulated by setting the conductivity of the fault, so that potential tapping of the remaining oil in the e
