Abstract

The invention discloses a physical simulation visualization experimental device and a forming method thereof. The experimental device comprises a cubic box body, a water injection well and a horizontal production well, wherein in the top of the box body is provided with a top cover, and the box body is filled with porous media; one end of the water injection well is arranged in the box body, the other end of the water injection well extends out of the box body to be exposed; the horizontal production well is horizontally arranged and comprises a main shaft, the tail end of the main shaft is connected with a connecting shaft, the side edge of the main shaft is provided with at least one branch shaft located on a horizontal plane of the main shaft, both the main shaft and the branch shaft are located in the box body, the connecting shaft is located on the outside of the box body, and the main shaft and the branch shaft are both evenly provided with a plurality of ejecting holes. The physical simulation visualization experimental device and the forming method of the physical simulation visualization experimental device can simultaneously simulate the horizontal production well and the water injection well in a three-dimensional simulation mode and can approximately simulate production trend of oil deposit.

Description

technical field [0001] The invention relates to a physical simulation visualization experiment device and a forming method thereof. Background technique [0002] The three-dimensional visualization physical simulation test system can intuitively and truly reflect the shape and rising speed of the water cone of the horizontal production well under different water content and production pressure difference during the development of the bottom water reservoir, and can reflect the water content of the horizontal production well. Flood dynamics and patterns. On the premise that the flow of fluid in the model device complies with Darcy's law of seepage, and the physical model experiment is comparable to the real reservoir, the three-dimensional visualization physical simulation test equipment is used to effectively simulate the use of horizontal production wells to exploit homogeneous bottom water. The formation and development process of bottom water ridges in reservoirs, as wel...

AI Technical Summary

Problems solved by technology

[0008] (3) There are large errors in the measurement system

However, in the actual wellbore, there is a certain wellbore resistance, and the impact of this resistance on the productivity of the reservoir cannot be ignored, so the plexiglass tube cannot objectively reflect the real situation of the wellbore in the reservoir

[0010] (5) This 3D visualization model is difficult to simulate thin reservoirs

For oil layers with thin reservoir thickness, this model cannot achieve

If this model is used to simulate reservoirs with thin oil layers, it is difficult to realize reservoir pressure, etc.
