Reservoir sensitivity flow evaluator is a kind of precision experimental equipment used to evaluate the permeability damage of oil and gas reservoirs due to changes in physical and chemical conditions during the exploitation process. Its core functions include: sensitivity evaluation experiment: by simulating formation pressure (up to 110MPa) and temperature (normal temperature to 180°C), speed sensitive, water sensitive, salt sensitive, acid sensitive, alkali sensitive and stress sensitive experiments are carried out to quantitatively analyze the permeability changes of reservoir rocks under the action of different fluids. Damage assessment: to determine the degree of contamination of the reservoir by external fluids such as drilling fluids and completion fluids, for example, to evaluate the loss of gas phase permeability through the water lock effect experiment (the comparison accuracy before and after pollution is 0.1%F· S）。 Multi-functional analysis: support core gas/liquid permeability determination, inlet fluid reverse injection, gas-liquid separation and other operations, in line with the industry standard SY/T5358-2010.
