Abstract

The invention provides a three-dimensional visible bottom water oil reservoir physical simulation device. The three-dimensional visible bottom water oil reservoir physical simulation device comprisesa frame body, a visible panel, a seepage partition plate and a pressing cover, the pressing cover is arranged at the top end of the frame body, and the frame body, the visible panel and the pressing cover constitute a sealed cube. The seepage partition plate is located in the frame body, and the frame body is divided into upper and lower layers. Granular porous mediums are laid on the upper part of the seepage partition plate, and a plurality of pipe strings for simulating a shaft are arranged in the granular porous mediums. According to the three-dimensional visible bottom water oil reservoirphysical simulation device, accurate visual physical simulation experiments can be carried out on a bottom oil water reservoir with different oil reservoir thicknesses, different well patterns and well types and different displacement modes so as to help researchers to study the law of oil and water seepage in the bottom water oil reservoir more accurately and guide the development of the bottomwater oil reservoir.

Description

technical field [0001] The invention relates to a physical simulation experiment device for bottom water reservoirs, in particular to a physical simulation device for three-dimensional visible bottom water reservoirs. Background technique [0002] During the development of bottom water reservoirs, the bottom water gradually pushes into the oil layer, forming the phenomenon of bottom water coning, which leads to premature water breakthrough in oil wells, a sharp drop in oil production and a rapid rise in water cut, seriously affecting the normal production of oil wells, and causing Increased water treatment costs and higher development costs. Therefore, it is particularly important to study the law of oil-water seepage in bottom water reservoirs during the production process. [0003] At present, the research methods for bottom water reservoirs are mainly realized by using professional reservoir numerical simulation software, and there are few studies on physical simulation ...
