Simulate five-spot network micro carve visualization model and apply method

Abstract

The application discloses simulate five-spot network micro carve visualization model and apply method, wherein comprising light focus cover, base seat, base seat seal wax film, carve glass film, observe glass film, light focus cover seal wax film, screw bolt; base seat and light focus cover aligns, joins by screw bolt, the middle chamber of observe seat and visualization hold seat overlays from bottom to top in sequence placement base seat seal wax film, carve glass film, observe glass film, light focus cover seal wax film. Micro carve visualization model carve glass film and observe glass film does not burn stick together, carve glass film is reusable after washing; model accords to actual oil deposit condition, simulates out path direction current by placing longitude pipe section, reflects truthfully out oil deposit mining fluid flowing pass well hole seeping status; the application model sets stepwise hole on light focus cover, places screw bolt head in stepwise hole, results unlikely convex shapes on light focus cover surface, facilitates placement and observation.

Description

technical field [0001] The invention relates to a five-point well pattern microscopic etching visualization model for simulating underground fluid flow and a use method thereof, belonging to the technical field of oil and gas field development. Background technique [0002] In order to study the contact relationship between fluids in rock pores and the mechanism of foreign fluids displacing crude oil in reservoirs, microscopic oil displacement physical simulation technology has become an important means for people to study microscopic oil displacement mechanisms. The visual physical model of the core or simulated core is connected to the flooding process, which requires a connection device, which is the function of the model holder. [0003] Since underground oil reservoirs are in a state of high temperature and high pressure, in order to more accurately simulate underground oil reservoirs and reflect the exploitation status of underground oil reservoirs, it is necessary to ...

The utility model patent application number 201510868706.4 discloses a preparation method of a microscopic oil displacement glass model. This method etches the base glass slide, and finally sinters the cover glass and the etched glass slide together to form a microscopic displacement glass model. However, the above-mentioned models all have certain defects in terms of repeated use. Although the current glass model can simulate the distribution of oil and water during the displacement process, due to the lack of manufacturing methods, it cannot completely clean the remaining fluid during the experiment, thus As a result, the model cannot be reused, and a new model needs to be purchased and processed every time, resulting in a huge waste of cost

The invention patent with the authorized announcement number CN103558135B discloses a reusable glass chip model, but this model does not set any structure that can directly observe the internal flow field, and can only draw conclusions by analyzing the pressure value, and cannot directly Observing the flow field, its accuracy is greatly reduced
