摘　　要：出砂预测是制定油气田开发方案的重要一环,科学地进行出砂预测可以为油气田完井方式选择提供决策依据。该文综合考虑国内外油气田常用的声波时差法、组合模量法、出砂指数法等多种出砂预测方法及含水率、原油黏度等因素对出砂的影响,通过评分法建立了出砂风险评估方法。利用该方法进行了实例分析,结果显示与油气田实际开发情况符合度较高。该方法考虑的因素更加全面、合理,在出砂预测分析研究上具有一定的推广应用价值。Sand production prediction is an important link in formulating oil and gas field development plans.Scientific sand production prediction can provide decision-making basis for the selection of oil and gas field completion methods.In this paper,considering various sand production prediction methods,which are commonly used in oil and gas fields at home and abroad,such as acoustic travel time method,combined modulus method and sand production index method,as well as the influence of water content,crude oil viscosity and other factors on sand production,a sand production risk assessment method is established by scoring method.The method is applied to the case analysis,and the results show that it is highly consistent with the actual development of oil and gas fields.The factors considered by this method are more comprehensive and reasonable,which has certain popularization and application value in sand production prediction and analysis.
