Abstract

Abstract: Based on the model of the experimental well group Wa 60-H25 in Block Wa-59 of Liaohe oilfield, a 3D model is designed for the experiment based on the similarity theory and a high-temperature and high-pressure resistant core model which is in accordance with the corresponding permeabilities is made according to geological conditions, and the corresponding experimental procedure and condition are designed, too. The transient liquid yield, transient oil production and the variations of watercut with time during the displacement are obtained from the experiment. The production process can be classified into 4 phases and the production performance of each phase is accurately described. The experimental method, model and results can be used for reference in future experiments of heavy oil gravity flooding and have important guiding significance for heavy oil development by gravity water-drainage assisted steam flooding
