Manufacturer of core sensitivity flow experimental device, equipment for core sensitivity flow experimental device

1、 Instrument functions

The instrument can conduct the following research under simulated formation pressure and temperature conditions

1. Determination of liquid permeability

At a certain flow rate, the liquid is passed through the core. By measuring the pressure difference between the inlet and outlet of the core and the flow rate of the liquid flowing through the core, combined with other parameters, the permeability of the core liquid is calculated according to Darcy's law.

2. Evaluation of formation sensitivity (formation damage), studying the damage caused by foreign substances to the formation during drilling, completion, water injection, production enhancement measures, and well repair operations, and methods to avoid or mitigate such damage.

3. Research on oil extraction technology, such as acidification, fracturing, water plugging, adjusting injection production profiles, and other experiments.

4. Research on improving oil recovery, secondary and tertiary oil recovery experiments.
