The imperbition experimental device in tight oil chamber is a special equipment used to simulate the physical and chemical process of displacing crude oil by capillary force of fluids (such as fracturing fluid, formation water, etc.) in tight reservoirs under formation conditions. Its core objectives are to study the imbibition mechanism, optimize the fracturing fluid formulation, determine the simmering time and other parameters to improve the recovery factor of tight reservoirs. This type of device is especially suitable for reservoirs with permeability less than 0.1mD, which can solve the problem of formation energy decline caused by the difficulty of fluid flow in the development of low-permeability reservoirs.

1. Core size: Φ25×50mm ~ Φ38×80mm Support standard plunger or full diameter core
2. Maximum confining pressure: 35MPa
3. Temperature resistance: 0-120°C
4. Corrosion-resistant materials: intermediate containers and pipelines are made of Hastelloy or 316L stainless steel, which are resistant to acidic/alkaline imbination.
