Reservoir Pressure Transmission Experimental Device

Reservoir Pressure Transmission Experimental Device

"Unable to inject, unable to produce" is a typical challenge encountered in unconventional reservoir development. Its intrinsic mechanism involves the pressure transmission speed and the seepage velocity controlled by the pressure field; the interaction between these two determines the oil well productivity and water well injection capacity. A 100cm long core has been established, capable of studying pressure transmission during water injection, gas injection, and elastic development processes. It also features an 8cm long core holder that allows pressure transmission testing using sealed coring. Equipped with a pulse-start pressure gradient inversion algorithm, it can calculate the relationship between different pressure gradients and flow rates, as well as the starting pressure gradient, through a set of experiments. It can accurately measure pressure transmission and fluid transport laws in tight cores under conditions up to 70.0MPa and 150°C, thereby providing strong technical support for the development of tight oil and gas reservoirs.
