摘　　要：在室内进行了简易防砂模拟实验,观察和模拟了控制环境条件下渤海常规稠油油藏的出砂行为,对出砂机理及各类生产工艺与参数对出砂的影响进行了分析。根据出砂试验结果论证了理论模型,并与现场生产状况相结合预测了出砂规律。模拟实验结果对于论证理论模型及确保适合本油区的“适度出砂,高产稳产”科学化管理措施提供了定量依据。A series of laboratory experiments on sand production behaviors of heavy oil reservoir in Bohai area were performed under different test conditions. The theoretical models were verified by the tested result of sand production. Real time changes of flow rate and sand production rate were measured under different injection pressure. The dynamic change of permeability was calculated using Darcy's law. The influences of pressure fluctuation on sand production and wormhole formation were analyzed. The experimental results can provide a quantitative base for the determination of proper sand control measures in field.
