Unconventional Reservoir Protection Instrument

Unconventional Reservoir Protection Instrument

The unconventional reservoir protection instrument can conduct reservoir damage evaluation experiments under simulated formation pressure and temperature conditions, especially simulating high temperature (180°C), high pressure (70MPa), and ultra-low permeability reservoirs (0.00001×10^-3 μm²). It can also perform experiments under strong acid and strong alkali conditions, including: (1) gas and liquid permeability measurement experiments; (2) reservoir damage evaluation experiments, studying the interaction between working fluids such as drilling fluid, completion fluid, and fracturing fluid with the reservoir during wellbore circulation, and the damage caused to the reservoir. It can simulate the shear of working fluids in the wellbore and measure fluid loss, studying the depth of damage. The following parameters can be measured: fluid loss, initial permeability, restored permeability, permeability damage rate, etc.; (3) sensitivity evaluation experiments including rapid sensitivity, water sensitivity, acid sensitivity, alkali sensitivity, salt sensitivity, stress sensitivity, and temperature sensitivity tests; (4) fracture plugging simulation experiments.
