Reference Standard SY/T5358-2010 Reservoir Sensitivity Flow Test Evaluation Method
1. Overview
The nature of the change of reservoir pore structure and permeability due to various physical or chemical interactions between oil and gas reservoirs and foreign fluids is called reservoir sensitivity. The intelligent reservoir sensitivity evaluation device developed by our company can carry out the following research under the condition of simulating formation pressure:
1, reservoir damage sensitivity evaluation experiment: including speed sensitivity, water sensitivity, acid sensitivity, alkali sensitivity, salt sensitivity and other experiments;
2, can also realize the core liquid permeability measurement, into the well fluid reverse injection damage rate measurement, fluid compatibility and anti-swelling agent stability;
