The device comprises an injection unit, a model body, an edge-bottom water temperature control unit, an edge-bottom water pressure control unit, a model insulation unit, a yield metering unit, a data acquisition and image processing unit and the like. The device is used for exploring the edge-bottom water oil reservoir steam driving mechanism, understanding the influence of edge-bottom water of oil reservoirs upon steam flooding effect and the development features and production features of a temperature field of edge-bottom water heavy oil reservoir steam driving, and guiding the development of edge-bottom water heavy oil reservoir steam driving.

Description

technical field [0001] The invention belongs to the field of geophysical exploration, and relates to numerical processing and simulation technology of physical exploration, in particular to a two-dimensional proportional physical simulation device for steam flooding in heavy oil reservoirs with edge and bottom water and a method for using the same. Background technique [0002] A commonly used method in heavy oil recovery is steam injection thermal recovery, in which steam huff and puff is an important method in steam injection thermal recovery. Steam huff and puff is to continuously inject a certain amount of steam into a production well in a short period of time, shut down the well for several days, and then start the well for production. Due to the short steam injection time, quick effect and good economic benefits, steam huff and puff is often used as a mining method before steam flooding at home and abroad. Another method of thermal recovery with steam injection is ste...

Problems solved by technology

[0005] (1) There is no simulation unit for edge water, bottom water or edge-bottom water, so it is impossible to carry out physical simulation experiments of steam flooding in reservoirs with edge-bottom water. The influence of edge-bottom water on steam flooding Development of oil recovery technology for water reservoirs;

[0006] (2) The pressure of the low-pressure model is only 0.1 MPa, which is quite different from the conditions of steam flooding reservoirs, and cannot fully reflect the production characteristics of steam flooding in heavy oil reservoirs;

[0007] (3) The pressure of the high-pressure model can reach tens of MPa, but the model must be placed in a high-pressure chamber, the operation is complicated, and the test period is long, which limits the progress of physical simulation research and requires a lot of manpower and material resources
