The existing quantitative measurement mode is omitted, and the device is high in precision and high in experimental defect and is convincing.

Description

technical field [0001] The invention relates to the technical field of oil and gas migration, in particular to the field of quantitative physical simulation of oil and gas migration paths, in particular to a real-time on-line quantitative physical simulation of oil and gas migration paths and a method. Background technique [0002] Oil and gas migration has always been a difficult problem that the oil and gas exploration industry urgently needs to solve. Before the 1990s, the focus of oil and gas migration research was the primary migration dynamics, phase state, process and its geochemical effects. Since the 1990s, the migration behavior of oil and gas in the transport layer has received more attention, because the secondary migration of hydrocarbon fluids in the lake basin is an extremely heterogeneous process, even in a uniform In porous media, the migration of hydrocarbon fluids also occurs only along limited paths within the channel (Showalter, 1979; Demibicki et al., ...

AI Technical Summary

Problems solved by technology

[0010] 1) The existing physical simulation of oil and gas migration paths is through image tracking during the simulation process or product detection and analysis before and after the simulation, which are mainly qualitative physical simulations, and have not realized the real-time online quantitative detection function during the simulation process, so Failure to meet the requirements of modern science and technology for experimental quantitative techniques;

[0011] 2) The existing physical simulation methods of oil and gas migration paths either do not consider the influence of charging pressure on the simulated path, or only consider the influence of inlet pressure on the simulation experiment. Since the actual underground oil and gas migration is dominated by the migration force, Formation pressure is one of the important driving forces for migration, and the oil and gas migration process is affected by inlet pressure and outlet pressure at the same time, that is, confining pressure and pressure relief conditions in the actual geological process. simulation experiment technology;

[0012] 3) The current existing technology does not solve the above two problems at the same time
