Circulating water bath high-temperature micro etching visualization clamping model and use method thereof

Abstract

The invention discloses a circulating water bath high-temperature micro etching visualization clamping model and a use method thereof. The model comprises a light condensing cover, a water bath base, a water bath base seal film, an etching glass sheet, an observation glass sheet, a light condensing cover seal film, a bolt, a gland and a nut; the water bath base and the light condensing cover are aligned and are connected through the bolt; the water bath base seal film, the etching glass sheet, the observation glass sheet and the light condensing cover seal film are sequentially placed in a cavity formed between the light condensing cover and the water bath base from bottom to top in an overlaid manner; the gland is mounted below the water bath base through the nut. Through integrated observation and heating functions, the etching glass sheet truly simulates the true seepage dynamic state of the underground oil deposit, and a water bath cavity of a base also can truly simulate various micro experiments at the temperature below 100 DEG C; the water bath cavity can carry out real-time circulation, through the water bath, the whole metal is heated, the metal can make face contact with the etching glass sheet for heating, heating is more uniform and stable, and the simulated site environment temperature is more true.

Description

technical field [0001] The invention relates to a microscopic etching visualization model for simulating underground fluid flow heated by a circulating water bath and an application 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] Many people have done research on the design of high-temperature microscopic models. Among them, in 2006, Ma Tonghai et al. "High-temperature and high-pressure glass microscopic model holder", application number 2006...

Problems solved by technology

However, these high-temperature microscopic grippers either do not have a heating module, or their heating model adopts linear contact, and the direct heating area is small, resulting in poor heating effect and uneven heating, which cannot simulate the formation temperature conditions well. the accuracy of the
