摘　　要：出砂预测方法的发展经历了一个从简单到复杂、从定性到定量的曲折发展过程。目前,随着稠油冷采和出砂管理新技术理论的提出,油气井开采过程中出砂量的预测更是成为迫切需要解决的问题。对弱胶结砂岩油藏出砂机理和出砂量预测技术的研究进展进行了综合论述。将油气井出砂预测模型分为:现场工程法、应力—应变分析模型、蚯蚓洞模型和流固耦合模型,指出了不同模型的适用范围及其相互联系,并针对各种预测方法的不足之处提出了研究方向。Prediction technique has experienced a process from simple to complex and from qualification to quantification. At present, with the proposing of new techniques of cold production of heavy oil and sand production management , prediction of sand production amount in oil and gas well production process becomes an important problem. This paper illustrates the development of technique of sand production mechanism and prediction of sand production amount in weak cementation sand stone reservoir. It divides sand production prediction models of oil and gas wells into field engineering method, stress-strain analysis model, earthworm hole model and flow and solid coupling model. It gives the application range of different models and relationship among them, and proposes study direction aiming at disadvantages of each model.
