technical field [0001] The invention relates to a simulation device, in particular to a multifunctional three-dimensional flow simulation closure device. Background technique [0002] In the process of petroleum exploration, development and production, indoor rubber sleeve flow experiments are required to solve many problems, and indoor rubber sleeve displacement experiments are mostly carried out with displacement experimental devices. [0003] At present, commonly used displacement devices can conduct experiments under one-dimensional and two-dimensional conditions for the study of microscopic characteristics; while experimental devices under three-dimensional conditions mostly use sand-packing model experimental devices, which can perform physical simulations under low-pressure conditions . The above-mentioned experimental devices cannot simultaneously realize the research on the flow field between injection-production wells and injection-production well groups and oil d...

AI Technical Summary

Problems solved by technology

The above-mentioned experimental devices cannot simultaneously realize the research on the flow field between injection-production wells and injection-production well groups and oil displacement efficiency under high temperature and high pressure conditions.

[0004] The existing three-dimensional large-scale physical simulation experimental devices cannot effectively simulate formation conditions, and cannot apply confining pressure and back pressure at the same time; most of the models used are sand-fill models or flat-plate models spliced ​​together, which have a large gap with the actual reservoir; Simultaneous testing of pressure field and saturation field cannot be realized; simultaneous measurement and collection of multi-well flow rates cannot be realized
