The invention discloses a preparation method of a three-dimensional oil reservoir water-displacement simulation model and a real-time dynamic monitoring visualization device, and relates to the fieldof oilfield water-injection development experiments. According to the digital research result of an oil reservoir and the actual demand, a 3D printing technology is utilized to print a sand-filling model frame, an oil reservoir bottom face and an oil reservoir fault frame, sand with different grain sizes are used for filling, impermeable plastic films are used for replacing a partition layer and interlayer, plastic pipes are used for simulating oil production wells and water injection wells, thus a constructed three-dimensional real oil reservoir miniature model is used for a displacement experiment, and the oil and water motion states in the water injection experiment process under different well network conditions are simulated; and then resistivity measuring instruments are buried intothe three-dimensional oil reservoir water-displacement simulation model, oil and water dynamic visualization is achieved through resistivity values at different positions and in different time, the residual oil distribution law is determined, and the basis is provided for programming of a development scheme, potential tapping of residual oil and implementing of yield-increasing measures.

Description

technical field [0001] The invention relates to the field of water injection development experiments in oil fields, in particular to a method for preparing a three-dimensional oil reservoir water flooding simulation model and a dynamic monitoring and visualization device. Background technique [0002] Due to the three-dimensional heterogeneity of oil layers in water flooding development oilfields, the phenomenon of water injection will appear in the process of water flooding development. Reservoir displacement experiments are very important basic experiments for oilfield development planning, development planning, and subsequent remaining oil research. They can provide basis for oilfield well pattern deployment, implementation of production stimulation measures, remaining oil research and potential tapping. [0003] At present, there are two main forms of reservoir displacement experiments: one is using core displacement; the second is 3D reservoir displacement simulation. ...

AI Technical Summary

Problems solved by technology

This is actually one-dimensional displacement, ignoring the heterogeneity of the reservoir in three-dimensional space, it cannot fully reflect the actual situation of water flooding in the reservoir, and it cannot monitor the dynamic changes of the water flooding front in the core in real time

The 3D reservoir displacement simulation experiment is to study the water flooding effect from the 3D space, but the existing 3D reservoir water flooding experiments cannot monitor the dynamic changes of the water flooding front in real time, and cannot quantitatively monitor the change of oil saturation inside the reservoir. It affects the effect of the experiment and reduces the guiding role of the experiment on oilfield development
