The injectivity variation prediction model for water flooding oilfields sustainable development

Waterflooding is the most commonly used oilfields development method, and the injectivity is the most critical factor for determining injectors count. Injectivity is usually based on actual on-field test, but lack of theoretical research. An analytical model was proposed to evaluate the water injectivity and predict the variation law. The decisive factor of the injectivity variation law was revealed through further mathematical analysis, and...
