A Combined Solution Model for Predicting Development Performance of Low Permeability Reservoirs

Abstract

Production prediction model and waterflooding characteristic equation considering threshold pressure were deduced. Based on them, a combined solution model was established, which can predict development indexes in low permeability reservoirs. The development indexes of a typical low permeability block YS2 were forecast using the combined solution model. Forecast results and actual production data fit well, which confirms the practicability and validity of the combined solution model. It has important practical significance to guide low permeability oilfield development.
