Abstract

The invention provides a rock core model and a visualized totally-closed real manufacturing method thereof. The manufacturing method comprises the following steps: step 1, placing an upper glass sheet (11), a real rock core slice (12) and a lower glass sheet (13) which are arranged in a laminated manner on a loading bearing plate (14); step 2, placing the upper glass sheet (11), the real rock core slice (12), the lower glass sheet (13) and the loading bearing plate (14) in a heating device for heating to enable the upper glass sheet (11) and the lower glass sheet (13) to be melted; step 3, cooling. The rock core model manufactured by the visualized totally-closed real rock core model manufacturing method can ensure sealing under a high temperature, high pressure and petroleum reservoir condition, is free from leakage and breakage, and has excellent light permeability.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development experiments, in particular to a method for manufacturing a visualized fully enclosed real rock core model, and it is also a rock core model. Background technique [0002] Microscopic seepage experiment is an important experimental technique for mechanism research in the field of oil and gas field development, and its core content is to observe the seepage process of fluid in the microscopic model. [0003] In order to simulate the seepage conditions of high-temperature and high-pressure reservoirs, microscopic models are divided into internal models and external models. The inner model is the observation medium, and the most commonly used one is the glass model; the outer model provides a high-temperature and high-pressure environment for the inner model, and has a heating system and a pressure-resistant design. [0004] At present, the internal model is mainly a glass etchi...
