The Research of Liquid Producing Capacity Variation Law in Water Controlled Reservoir

Abstract

Through relative permeability, we can calculate core water cut ratio, dimensionless fluid productivity index and production index curve. And according to the data provided by the site, we can calculate actual water-cut, dimensionless fluid productivity index and production index curve in demonstration zone. Then we compare with the theoretical curves. By using combination reservoir engineering theory and dynamic production data method, we study the variation law of reservoir liquid producing capacity.
