Description

technical field [0001] The invention relates to a microscopic visual displacement simulation system and a using method thereof, belonging to the technical field of oil and gas field development. Background technique [0002] At present, in the research of oil and gas field development process, the development from macro to micro has become an irresistible trend. A large number of microscopic models have appeared and are used in microscopic simulation experiments of oil and gas production. There are many types of microscopic models, and the glass microscopic model stands out in the application of many microscopic models. Making glass models is inseparable from the development of photolithography technology, the essence of which is photoresist technology. The microscopic oil displacement system is a scientific research project that has been studied more in oil and gas field development experiments in recent years. By observing the visualized microscopic oil displacement mode...

The Chinese patent application number 201510236593.6 "A Microscopic Displacement Experimental System and Microscopic Displacement Experimental Method Based on CT Digital Core" adopts CT scanning technology to reproduce the change of fluid distribution in pores, which is costly and expensive. The speed is slow, and secondary deviations are prone to occur during image regeneration; the Chinese patent "Heavy Oil Thermal Recovery Micro-displacement Experimental System" with application number 201410642984.3 cannot achieve the continuous and constant pressure required for the experiment during displacement; application number The Chinese patent of 201410500078.X "A Two-dimensional Microscopic Visible Displacement Simulation Experimental System for Heavy Oil and Its Application Method" uses a high-definition camera as the observation system, and the resolution of the camera system is often insufficient in the experimental environment. The situation of the microscopic model can be clearly observed; the Chinese patent "High Temperature and High Pressure Microscopic Experiment Holder" with the application number of 200820123024.6, the model used has only one intermediate container, which cannot realize multiple displacements, and the intermediate container does not have insulation effect and affect the experimental test results; although the current microscopic physical displacement model can simulate the distribution of oil and water during the displacement process, due to the limitations of the device, it cannot restore the displacement conditions well, and it cannot reach the essence of the experimental simulation. , the existing technology is mostly connected to the six-way valve through multiple intermediate containers, and the communication with different intermediate containers is realized by changing the channel of the six-way valve. Due to the artificial time interval of the six-way valve switching switch, there will be a The fluid returned to the six-way valve under the existing injection pressure, resulting in experimental errors; and controlled by pneumatic control components, the switch can be reversed in an instant, which can reduce the influence of backflow and make the experiment more accurate
