High-pressure-resistant visible automatic compaction model

Abstract

The invention relates to a high-pressure-resistant visible automatic compaction model. The model comprises a high pressure cavity, a rotary mobile mechanism, a control box, a safety valve system, an observation device and a visible model. The high pressure cavity is connected on the rotary mobile mechanism. The control box is arranged on the rotary mobile mechanism. The observation device is arranged at the upper part of the high pressure cavity. The visible model is arranged in the high pressure cavity. The high pressure cavity comprises a cavity and an end cap. The cavity and the end cap are connected via bolts. The visible model comprises a model body, a pressing plate, high pressure glass and a sealing member. The pressing plate is connected at the upper part of the model body. High pressure glass is arranged between the pressing plate and the model body. A test sample is arranged on the model body. A piston pressing plate is arranged at the lower part of the test sample. The flow state and distribution of fluid in the model under the high temperature and high pressure state are directly observed via image acquisition, and various fluid proportions, recovery efficiency and phase change are tested so that the compaction effect is great.

Description

technical field [0001] The invention relates to a high-pressure-resistant visible automatic compaction model. Background technique [0002] The high-pressure-resistant visual models in such fields are generally small in size, while the larger-volume visual models can only withstand low pressure, generally only 0.5-1MPa pressure; with the improvement of experimental simulation requirements, visual visualization and intuitive The experimental results can be seen clearly, but the previous models cannot be visualized; the experiment is generally filled with experimental samples such as fluid or sand, and the filled sand cannot be completely compacted under high pressure, and there are often phenomena such as cross flow, which affects the The entire experimental effect and results, the existing models need to be improved in the above aspects. Contents of the invention [0003] The purpose of the present invention is to provide a method of directly observing the flow state and ...
