摘　　要：分析了造成地层污染的原因、机理及诊断方法;提出了酸化选井的原则及酸化选井的经验法和模糊综合评判法,提出了用动态参数计算地层静态参数及酸化效果预测的数学模型,通过实例验证,预测日注入量与实测日注入量的平均相对误差为5.6%.The analyses of cause, mechanism and diagnosis method arising from formation pollution were made. The principle, empirical method and fuzzy comprehensive identification method for selecting acidizing well were proposed. A mathematical model for calculating formation statics parametersand predicting acidizing effect with performance parameter was developed. Practical example proved that there is an average relative error of 5.6% between predicted and actual daily injection rate.
